Emergent phenomena in non-equilibrium quantum systems
Abstract
One of the pillars of modern condensed matter physics is the concept of emergence: at large scales and low energies, new symmetries and properties can emerge in a universal way that is largely independent of microscopic details. In contrast, the dynamics of many-body quantum systems in non-equilibrium settings can appear intricate: highly excited eigenstates are involved in generic time evolution, seemingly leaving very little room for interesting emergent phenomena. On the other hand, the field of non-equilibrium many-body quantum physics remains largely uncharted territory; and works from recent years have revealed the existence of remarkable dynamical phenomena such as many-body localization, anomalous transport or many-body quantum scars. The study of many-body quantum systems in non-equilibrium settings opens the door to new and exciting questions about dynamics, thermalization, and emergence beyond traditional condensed matter paradigms. These questions are strongly motivated by the advent of ultra-cold atomic, molecular, and trapped ion systems that offer promising experimental platforms to investigate the dynamics of closed quantum systems. Recent experimental advances in ultrafast optics and pump-probe spectroscopy, solid-state qubits, ultra-cold gases or quantum nanostructures have opened up exciting avenues for non-equilibrium quantum physics including the discovery of novel dynamical phases of matter with no equilibrium counterparts, and the emergence of non-equilibrium universality classes.
