Europe/Rome Biosketch: Prof. Liliana Arrachea from the International Center for Advanced Studies, Universidad Nacional de San Martín in Argentina obtained her PhD from Universidad Nacional de La Plata, Argentina in 1995. Following this, her research positions have included Alexander von Humboldt fellow at FU-Berlin and Max-Planck Institut, Germany, Postdoctoral researcher at SISSA, Trieste, and Ramón y Cajal Researcher at University of Zaragoza. She has been a Researcher of CONICET Argentina since 1999, an Associate Professor from University of Buenos Aires since 2007 (on leave since 2016), and Full Professor at University of San Martín, Argentina since 2016. In addition, Prof. Arrachea was appointed Guggenheim Fellow 2010, and Simons Associate at ICTP-Trieste since 2015, and Georg-Forster Alexander-von-Humboldt Research Award 2016. Prof. Arrachea spends periods comprising several months at a time as Invited Professor at PUC-Rio de Janeiro, Université Paris 7, and Boston University. Abstract: Boosting the efficiency for the conversion of electrical and thermal energy at finite power is motivating an intense research activity, not only in the areas of material science and applied physics but also in experimental and theoretical areas of statistical mechanics and condensed matter physics. Efforts are concentrated in developing new materials and devices as well as on analyzing different operational conditions. In the latter direction, taking advantage of the quantum effects is one of the most interesting avenues. Nanoscale devices and topological materials provide an excellent scenario to explore these properties. In this talk, I will present a general overview on the field. I will also present some examples and discuss some fundamental theoretical aspects. The talk will take place on 28 August 2019 at 16.30 in the Euler Lecture Hall @ ICTP. Light refreshments will be provided. All are welcome to attend. ICTP ICTP pio@ictp.it

ICTP CMSP Colloquium on Heat to Work Conversion in the Quantum Regime

Address: Strada Costiera 11 34151 Trieste Italy

Room: Leonardo Building - Euler Lecture Hall

Speaker(s): Prof. Liliana Arrachea, Universidad Nacional de San Martín, Argentina

Colloquium Start Time: 16:30

Europe/Rome Timothy Beers is the Grace-Rupley Professor of Physics at the University of Notre Dame, and a co-PI in the Physics Frontier Center JINA-CEE (Joint Institute for Nuclear Astrophysics – Center for the Evolution of the Elements), funded by the US National Science Foundation. He is a former director of the US Kitt Peak National Observatory, and spent 25 years working as a Professor in Physics & Astronomy at Michigan State University. Beers is interested in the origin and evolution of the elements in the Universe, and the assembly of large spiral galaxies such as the Milky Way, a field now referred to as Galactic Archaeology. For decades, Professor Beers has designed and executed large-scale surveys of stars in the Milky Way, efficiently sifting through literally millions of individual stars in order to find those objects that have recorded the chemical history of the Universe in their atmospheres. His work has led to the identification of a subset of the so-called carbon-enhanced metal-poor (CEMP) stars that exhibit a characteristic light-element signature (enhanced C, N, O, Na, Si, Mg), now recognized to be due to nucleosynthesis processes associated with the very first stars born in the Universe. Presently he is conducting a survey for so-called r-process-enhanced stars, which are metal-poor stars that exhibit over-abundances of elements produced by the rapid neutron-capture process, and place strong constraints on the origin of over half of the elements beyond iron in the Periodic Table. Abstract: In this, the 150th Anniversary year of Mendeleyev’s Periodic Table, astronomers have pieced together plausible origin stories for most of the elements formed in nature. From the breakthrough observations of Paul Merrill (1952), which first demonstrated that essentially all elements beyond H and He were formed in stars, to the discovery of the astrophysical origin of the rapid neutron-capture elements in binary neutron star mergers (2017), I present a summary of our modern understanding of this fascinating history. I also highlight a number of remaining questions, and how astronomers and physicists are working to fill in our gaps in knowledge. The talk will be livestreamed from the ICTP website. Light refreshments will follow the event. ICTP ICTP pio@ictp.it

ICTP Colloquium by Christopher Jarzynski

Address: Strada Costiera 11 34152 Trieste Italy

Room: Leonardo Building - Budinich Lecture Hall

Speaker(s): Professor Christopher Jarzynski, University of Maryland, USA

Colloquium Start Time: 16:30

Europe/Rome Petra Rudolf was born in Munich, Germany. She studied Physics at the La Sapienza, University of Rome, where she specialized in Solid State Physics. In 1987 she joined the National Surface Science laboratory TASC INFM in Trieste for the following five years, interrupted by two extended periods in 1989 and 1990/1991 at Bell Labs in the USA, where she started to work on the newly discovered fullerenes. In 1993 she moved to the University of Namur, Belgium where she received her PhD in 1995 and then quickly moved from postdoctoral researcher to lecturer and senior lecturer before taking up the Chair in Experimental Solid State Physics at the University in Groningen in 2003. Her principal research interests lie in the areas of condensed matter physics and surface science, particularly molecular motors, 2D solids, organic thin films and inorganic-organic hybrids. Dr. Rudolf is the President of the European Physical Society; she was the President of the Belgian Physical Society in 2000/2001 and was elected member of the German Academy of Science and Engineering,honorary member of the Italian Physical Society, Fellow of the Institute of Physics, "Lid van verdienst" of the Dutch Physical Society and Fellow of the American Physical Society. For her work on molecular motors she received the 2007 Descartes Prize of the European Commission. In 2013 she was appointed Officer of the Order of Orange Nassau by H.M. Queen Beatrix of the Netherlands. Abstract: Nano-engines and molecular motors form the basis of nearly every important biological process. In contrast to this solution chosen by Nature for achieving complex tasks, all of mankind's present day technologies function exclusively through their static or equilibrium properties. One can therefore easily anticipate that the controlled movement of molecules or parts of molecules offers unprecedented technological possibilities for the future. In this presentation I shall illustrate how introducing new concepts like incorporating a ratchet mechanism, allows for the creation of molecular engines that transcend simple switches. I shall discuss how to build molecular engines that allow movements at the molecular level to be coupled to the macroscopic world, e.g., to transport macroscopic objects like drops of liquid over a surface. Another example are molecular systems that can be triggered to form spontaneously functional structures with a well-defined position on surfaces. I shall discuss molecular switches, which can be addressed with light and charge transfer and show that such systems can be employed for “read and write” functions. The talk will be livestreamed from the ICTP website. Light refreshments will follow the event. The event is open to all those interested. ICTP ICTP pio@ictp.it
