El coloquio del Instituto Balseiro del viernes 08 de marzo se titula: "Quantum time-crystals". El expositor es Rosario Fazio - Profesor Invitado del Programa Maldacena del International Centre for Theoretical Physics (ICTP), Trieste, Italy and NEST, Scuola Normale Superiore & Istituto Nanoscienze-CNR, Pisa, Italy
Se realizará a las 14.30 hs. 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.
Landau's idea of classifying phases of matter in terms of symmetry breaking is a cornerstone of modern physics. Can time-translation invariance be spontaneously broken? The possible existence of time-crystals was first addressed by Wilczek for quantum many-body systems launching an intense activity both theoretically and experimentally. Despite their conceptual simplicity and apparent similarity to ordinary crystals, they were experimentally observed only two years ago, eighty years after the Landau theory of symmetry breaking. I will review the field focusing in particular on the so called Floquet time-crystals arising in many-body systems that are periodically driven. I will also briefly address prospects to observe continuous time-crystals and their relation to quantum synchronisation.
Received his PhD in Physics in 1990 from the University of Catania (Italy) he was appointed Professor in Condensed Matter theory at International School for Advanced Studies (SISSA) in 2005. He is currently Head of the Condensed Matter and Statistical Physics Section at ICTP and Professor of Theoretical Condensed Matter (on leave) at Scuola Normale Superiore in Pisa. His research interests include various aspects of the theory of condensed matter systems with a particular focus on: Quantum simulators, Quantum Transport in Nanostructures, Quantum information & many-body systems.
