TÍTULO: The Ising model at 100 – alive and quantum

ORADOR y FILIACIÓN: Felix von Oppen, FU-Berlin

RESUMEN:

This year marks the centennial of the publication in which Ernst Ising introduced the model that carries his name. Its quantum version, the transverse field (or quantum) Ising model, is not only important for solving the classical Ising model. It is also pervading large swaths of modern quantum condensed matter physics, quantum information theory, and beyond. It is the drosophila for symmetry-breaking quantum phase transitions in its spin incarnation, for topological quantum phase transitions and Majorana zero modes in its fermionic form, for lattice gauge theory and topological quantum error correction in its dual formulation, and for Majorana pi modes and discrete time crystals as a Floquet model. In this talk, I will review some of these connections and developments, guided by our analysis of a recent experiment on the random-field Floquet quantum Ising model using a superconducting quantum information processor.

MINI-BIO DEL ORADOR:
Felix von Oppen is a theoretical condensed matter physicist and professor at Freie Universität Berlin. His research interests are in topological states of matter and their application to topological quantum computation as well as in strongly correlated and nanoscale electron systems. Felix von Oppen obtained his PhD from the University of Washington, held postdoctoral and temporary researcher positions at the Max-Planck-Institute for Nuclear Physics in Heidelberg, the Weizmann Institute of Science in Israel, and the University of Cologne before joining Freie Universität Berlin in the year 2000.
