Quantum information processing relies on the precise control of non-classical states in the
presence of many uncontrolled environmental degrees of freedom. The interactions …

In Floquet engineering, periodic driving is used to realize novel phases of matter that are
inaccessible in thermal equilibrium. For this purpose, the Floquet theory provides us a recipe …

A state of an open quantum system is described by a density matrix, whose dynamics is
governed by a Liouvillian superoperator. Within a general framework, we explore …

Photonic synthetic materials provide an opportunity to explore the role of microscopic
quantum phenomena in determining macroscopic material properties. There are, however …

The possibility to simulate the properties of many-body open quantum systems with a large
number of degrees of freedom (dof) is the premise to the solution of several outstanding …

We overview the concept of dynamical phase transitions (DPTs) in isolated quantum
systems quenched out of equilibrium. We focus on non-equilibrium transitions characterized …

We experimentally explore the dynamical optical hysteresis of a semiconductor microcavity
as a function of the sweep time. The hysteresis area exhibits a double power law decay due …

Understanding and characterizing phase transitions in driven-dissipative systems
constitutes a new frontier for many-body physics,,,,,,–. A generic feature of dissipative phase …

The theory of open quantum systems lays the foundation for a substantial part of modern
research in quantum science and engineering. Rooted in the dimensionality of their …

We study an array of coupled optical cavities in the presence of two-photon driving and
dissipation. The system displays a critical behavior similar to that of a quantum Ising model …
