New Physics Gateway

A number of atomic, molecular, and optical science (AMOS) research groups around the world have banded together to create the Atomic, Molecular, and Optical Science (AMOS) Gateway project with help from XSEDE. This gateway makes a subset of their codes available in a form that enables the larger AMOS community to use them for their own purposes. 

PI Dr. Barry Schneider of NIST sought XSEDE as a “natural avenue” for developing the gateway. Through XSEDE allocations, including computational resources and ECSS support to create and deploy the gateway, the AMOS gateway now makes 11 (and counting) codes available for use by the larger AMOS community.

These codes are employed to help model problems in physics, and chemistry that have applications to fusion, astrophysics, quantum simulators, the etching of computer chips, and real-world devices that we all depend upon, such as fluorescent light bulbs. The gateway is also being utilized to teach atomic physics to students, which provides them with basic knowledge of AMOS and an invaluable hands-on learning experience. 

This work has been presented at PEARC19PEARC20, and is available on the arXiv. More info: https://www.xsede.org/-/xsede-helps-develop-new-physics-gateway

Tracking electron motion in molecules is the key to understanding and controlling chemical transformations. Contemporary techniques in attosecond science are able to generate and trace the consequences of this motion in real time, but not in real space. Scanning tunnelling microscopy, on the other hand, can locally probe the valence electron density in molecules, but cannot alone provide dynamical information at this ultrafast timescale. Here we show that, by combining scanning tunnelling microscopy and attosecond technologies, quantum electronic coherences induced in molecules by <6-fs-long carrier-envelope-phase-stable near-infrared laser pulses can be directly visualized at ångström-scale spatial and subfemtosecond temporal resolutions. We demonstrate concurrent real-space and -time imaging of coherences involving the valence orbitals of perylenetetracarboxylic dianhydride molecules, and full control over the population of the involved orbitals. This approach opens the way to the unambiguous observation and manipulation of electron dynamics in complex molecular systems.

TOMATTO project awarded with an ERC Synergy Grant

Today, 5 November 2020, the European Research Council (ERC) has announced that the project TOMATTO – “The ultimate time scale in organic molecular opto-electronics, the attosecond”, led by Fernando Martín (IMDEA Nanoscience and Universidad Autonoma de Madrid), Mauro Nisoli (Politecnico di Milano) and Nazario Martín (Universidad Complutense de Madrid) has been awarded a Synergy Grant that amounts to almost 12 million euros for the next 6 years.

The ultra-fast motion of electrons induced by the interaction with light is the basis of the conversion of solar energy into electrical energy and plays a crucial role in fundamental processes in Nature such as photosynthesis, the transport of signals in biological molecules, the mechanisms of DNA damage, and many others. The common denominator in all these processes is the absorption of light and the generation of microscopic electric currents. What happens inside the individual molecules immediately after the interaction with light is still a mystery, because light initiates events that evolve on extremely short time scales, of the order of attoseconds (i.e. of a few billionths of billionths of a second).

TOMATTO, which will be developed by a team of experts in laser technologies, the synthesis of new organic materials and computational methods, aims at filming the motion of electrons induced by light in molecules, with an unprecedented temporal resolution, with the aim of designing molecular materials with improved opto-electronic properties. To do this, a new attosecond laboratory at the forefront of the international arena will be built at the Attosecond Research Center (www.attosecond.fisi.polimi.it) of the Politecnico di Milano, a new supercomputer incorporating the latest advancements in hardware and software developments will be installed at the Computer Center of the Universidad Autónoma de Madrid, and new opto-electronic organic materials, with still unforeseen capabilities, will be synthesized at Complutense University.The project synergistically combines the development of innovative laser technologies and new measurement methods with extreme time resolution, with the most advanced methods of organic synthesis and computational modeling. “Understanding how light interacts with matter on the attosecond time scale – says Fernando Martín- and how the ultra-rapid motion of electrons depends on the molecular structure, are in themselves extremely important scientific objectives. The ability to understand and control these processes on the time scale of attoseconds offers the possibility of opening up new research fields beyond the scope of the project. In particular, we foresee important applications to the study of light-guided processes in a variety of both natural and artificial structures, ranging from systems of biological interest, to advanced materials with new functionalities. TOMATTO has the potential to lead to important and not easily predictable discoveries and advances: a typical example of high-risk high-gain research ”.

Polypeptide formation in clusters of β-alanine amino acids by single ion impact

The formation of peptide bonds by energetic processing of amino acids is an important step towards the formation of biologically relevant molecules. As amino acids are present in space, scenarios have been developed to identify the roots of life on Earth, either by processes occurring in outer space or on Earth itself. We study the formation of peptide bonds in single collisions of low-energy He2+ ions (α-particles) with loosely bound clusters of β-alanine molecules at impact energies typical for solar wind. Experimental fragmentation mass spectra produced by collisions are compared with results of molecular dynamics simulations and an exhaustive exploration of potential energy surfaces. We show that peptide bonds are efficiently formed by water molecule emission, leading to the formation of up to tetrapeptide. The present results show that a plausible route to polypeptides formation in space is the collision of energetic ions with small clusters of amino acids.See full text here:

IDEAS project is awarded with an ERC Advanced Grant

The UAM professor Fernando Martín, from the Department of Chemistry of the Faculty of Sciences has obtained funding from the European Research Council to develop the IDEAS project (Imaging, Decoherence and AttoSecond probing of ionization-induced charge migration in molecules)

The European Research Council (ERC) has selected the “Imaging, Decoherence and AttoSecond probing of ionization-induced charge migration in molecules” (IDEAS) project, led by the Professor of Physical Chemistry at the Autonomous University of Madrid ( UAM), Fernando Martín, to be financed by the ERC Advanced Grant program. It is the second time that the CampuS group receives one of these grants.

This project is one of the 82 projects in the category of Physical Sciences and Engineering that the ERC is going to finance this year 2020. According to the leading researcher its objective is to understand, and eventually predict, the first stages of charge migration processes in complex molecules, occurring in the time range of attoseconds (10-18 seconds). To do this, the team will have to develop and validate the theoretical methodology necessary to describe the effects that such migration produces experimentally, with the additional complication that existing techniques for simple atoms and simple molecules are not trivially extensible for complex ones.

The computational codes to be developed within the IDEAS project will provide a description of ionization and charge migration in relatively complex molecules, with a level of detail unprecedented to date. This is an essential step for the establishment and consolidation of attosecond science as a discipline that, beyond revolutionizing our basic knowledge of the electronic processes that occur in matter, allows addressing problems of practical interest in physics and chemistry.

Obtaining this ERC grant will boost the research that we have been developing in our group in recent years and, in particular, will allow us to continue advancing in the development of new attosecond experiments aimed at understanding and controlling chemical processes in a time scale inaccessible to date. This could allow us to generate more efficient charge transfer processes than those currently used in, for example, optoelectronic and photovoltaic devices. In addition, the project will reinforce the investigations carried out within the framework of the European CA18222 Action (AttoChem) that we coordinate from the Autonomous University of Madrid ”, explained Professor Martín.

FERNANDO MARTÍN GARCÍA graduated in Chemical Sciences (Quantum Chemistry specialty) in 1984 and in Physical Sciences (Theoretical Physics specialty) in 1986 at the Autonomous University of Madrid. He obtained his doctorate at that university in 1986 and obtained the extraordinary doctorate award. Subsequently, he completed postdoctoral stays at the Université de Bordeaux I (1988), the Université de Paris VI (1989-1990) and the University of Chicago (1995-1996). He has been Full Professor at the Autonomous University of Madrid from 1993 to 2005 and, since then, Professor of the same in the area of ​​Physical Chemistry.
His research work has focused mainly on the theoretical and computational modeling of photoexcitation and photoionization processes in atomic and molecular systems induced by synchrotron radiation and ultrashort laser pulses with femto- and atosecond durations, as well as in the theoretical study and prediction of properties of materials and nano-objects, of complex molecular systems, aggregates and fullerenes, isolated or deposited on metallic and non-metallic surfaces. All of this, in close collaboration with prestigious Spanish and European experimental groups.
He has directed 24 doctoral theses, is co-author of several scientific codes (XChem, FullFun, M3C), and has published nearly 500 articles, among which several stand out in the journals Science, Nature, Chemical Reviews, Nature Chemistry, Nature Physics, Nature Photonics, Nature Communications, Proceedings of the National Academy of Science, Physical Review Letters, Angewandte Chemie, Journal of the American Chemical Society, ACS Nano, Advanced Materials, Small, Nano Letters, as well as various reviews and book chapters.
He has also received numerous awards, including the Rey Juan Carlos I National Research Prize (2000); the prize from the Royal Spanish Society of Chemistry in Physical Chemistry (2010), the Advanced Grant XCHEM from the European Research Council (2011), and the Rey Jamie I Prize in Basic Research (2017). He has been the coordinator of two COST Actions for European cooperation, the first between 2008 and 2012 (CUPSFEL, CM0702) and the second, mentioned above, in attosecond chemistry, from 2019 to 2023 (AttoChem, CA18222).

The European Research Council (ERC) is the main European funding organization for excellent frontier research and is part of the Horizon 2020 research and innovation program. Each year, it selects and funds the best creative researchers of any nationality and age to execute projects carried out in Europe. In this year’s call, researchers and teachers from 26 nationalities have been selected. Germany, the United Kingdom and France are the countries with the highest number of projects in a classification in which Spain ranks sixth, with 14 selected. In total, 450 million euros will be allocated to finance the 185 researchers who have won some of the grants from this call.

As explained in a statement by the promoters of this European initiative, these research projects will not only help to strengthen the European knowledge base, but will also allow the creation of 1,800 new jobs for postdoctoral researchers, doctoral students and other related jobs.

Article: published in Nature Communications by Sergio Díaz-Tendero and Fernando Martín, IFIMAC researchers, in collaboration with the group of Nora Berrah, Univ. Connecticut, USA.

Being the lightest, most mobile atom that exists, hydrogen plays an important role in the chemistry of hydrocarbons, proteins and peptides and most biomolecules. Hydrogen can undergo transfer, exchange and migration processes, having considerable impact on the chemical behavior of these molecules. Although much has been learned about reaction dynamics involving one hydrogen atom, less is known about those processes where two or more hydrogen atoms participate. Here we show that single and double hydrogen migrations occurring in ethanol cations and dications take place within a few hundred fs to ps, using a 3D imaging and laser pump-probe technique. For double hydrogen migration, the hydrogens are not correlated, with the second hydrogen migration promoting the breakup of the C–O bond. The probability of double hydrogen migration is quite significant, suggesting that double hydrogen migration plays a more important role than generally assumed. The conclusions are supported by state-of-the-art molecular dynamics calculations.
