El coloquio del Instituto Balseiro del viernes 14 de septiembre se titula: “Cold atomic gases and quantum simulators”. El orador será el Prof. Thierry Giamarchi, de la Université de Genève, Switzerland.
Se realizará como todos los viernes a las 14.30 hrs. en el Salón de Actos del Instituto Balseiro, en el Centro Atómico Bariloche (Av. Bustillo 9500). La entrada es gratuita y abierta a todo el público. Para ingresar, es necesario presentar el DNI en la entrada del CAB.
In the recent years tremendous progress have been made in the preparation, trapping and cooling ofatomic gases to abysmally low temperatures. This has allowed to realize with an unprecedented level ofcontrol systems of many quantum particles interacting with each other. The nature of the particles, thelattice in which they move and even their interactions can be controlled at will. This has allowed to createin the laboratory systems that are close realizations of phenomena ranging from the ones found in solids,to neutron stars, such as superconductivity. This transformed cold atomic gases as a quantumsimulators, namely experiments that reproduces so perfectly a phenomenon or a given model, thatmeasuring the experiment ``solves’’ the model. This has not only allowed to address some of the majorquestions that were present in quantum many body physics, but also opened new avenues to studyphenomena hard to tackle previously, in particular concerning non-equilibrium physics, disorder or verylarge magnetic fields. I will present in this talk some of the examples of this success story, as well assome of the concepts that emerged from this new field. I will also discuss how cold atomic gases andcondensed matter started to go hand in hand in addressing some of the major issues of the field, as wellas some of the challenges that put some spices in this otherwise idyllic love story.
Thierry Giamarchi graduated from Ecole Normale Superieure in Paris and received hisPhD from Paris XI University in 1987.He has been a permanent member of the french CNRS since 1986,and between 1990-1992 was a postdoc/visitor at Bell Laboratories. In 2002 he moved as a full professorto the Condensed Matter Department at the University of Geneva. Since 2013 he is a member of theFrench Academy of Sciences, and a fellow of the American Physical Society. His research work dealswith the effects of interactions in low dimensional quantum systems, such as Luttinger liquids, and on theeffects of disorder in classical and quantum systems with works showing the existence of noveldisordered phases such as the Bose glass and the Bragg glass.
