Process Tensor Approaches to Non-Markovian Quantum Dynamics
Jonathan Keeling, E. Miles Stoudenmire, Mari-Carmen Bañuls +1
The paradigm of considering open quantum systems -- i.e. focusing only on the system of interest, and treating the rest of the world as an effective environment -- has proven to be…
Theory of dynamical superradiance in organic materials
Lukas Freter, Piper Fowler-Wright, Javier Cuerda +3
We develop the theory of dynamical superradiance -- the collective exchange of energy between an ensemble of initially excited emitters and a single-mode cavity -- for organic mate…
Measurement-Induced Dynamical Quantum Thermalization
Marvin Lenk, Sayak Biswas, Anna Posazhennikova +1
One of the fundamental problems of quantum statistical physics is how an ideally isolated quantum system can ever reach thermal equilibrium behavior despite the unitary time evolut…
A multimode cavity QED Ising spin glass
Brendan P. Marsh, David Atri Schuller, Yunpeng Ji +5
We realize a driven-dissipative Ising spin glass using cavity QED in a novel ``4/7" multimode geometry. Gases of ultracold atoms trapped within the cavity by optical tweezers serve…
Phase Transitions in Nonreciprocal Driven-Dissipative Condensates
Ron Belyansky, Cheyne Weis, Ryo Hanai +2
We investigate the influence of boundaries and spatial nonreciprocity on nonequilibrium driven-dissipative phase transitions. We focus on a one-dimensional lattice of nonlinear bos…
Many-Body Open Quantum Systems
Rosario Fazio, Jonathan Keeling, Leonardo Mazza +1
These Lecture Notes discuss the recent theoretical advances in the understanding of open quantum many-body physics in platforms where both dissipative and coherent processes can be…
