Join us today with Dr. Pedram Roushan from Google Research as we dive deep into the world of quantum many-body systems. We'll explore the fascinating phenomena of dynamical phases and the concept of discrete time crystals (DTC), revealing the wonders of out-of-equilibrium quantum systems.

Nature's Non-equilibrium State:

Quantum many-body systems have rich phase structures in low-temperature equilibrium states.

However, nature often exists out-of-equilibrium, leading to intriguing dynamical phases not seen in equilibrium.

The Novelty of Dynamical Phases:

Recent predictions suggest dynamical phases might exist that are forbidden by conventional equilibrium thermodynamics.

A prime example is the discrete time crystal (DTC).

Understanding Eigenstate Order:

Dynamical phases in periodically driven many-bo ...
