Condensed matter physics has been driven forward by significant experimental and
theoretical progress in the study and understanding of equilibrium phase transitions based …

Open many-body quantum systems have attracted renewed interest in the context of
quantum information science and quantum transport with biological clusters and ultracold …

Historically, noise in superconducting circuits has been considered an obstacle to be
removed. A large fraction of the research effort in designing superconducting circuits has …

In the present work we investigate the existence of multiple nonequilibrium steady states in a
coherently driven XY lattice of dissipative two-level systems. A commonly used mean-field …

Methods for modeling large driven-dissipative quantum systems are becoming increasingly
urgent due to recent experimental progress in a number of photonic platforms. We …

We realize tunable coupling between two superconducting transmission line resonators.
The coupling is mediated by a non-hysteretic rf SQUID acting as a flux-tunable mutual …

Lattice models of fermions, bosons, and spins have long served to elucidate the essential
physics of quantum phase transitions in a variety of systems. Generalizing such models to …

We propose a platform for quantum many body simulations of dipolar spin models using
current circuit QED technology. Our basic building blocks are 3D transmon qubits where we …

We investigate theoretically the Bose–Hubbard version of the celebrated Su-Schrieffer-
Heeger topological model, which essentially describes a one-dimensional dimerized array …

We investigate two coupled nonlinear cavities that are coherently driven in a dissipative
environment. We perform semiclassical, numerical, and analytical quantum studies of this …
