Hydrodynamic stabilization of self-organized criticality in a driven Rydberg gas
K. Klocke, T. M. Wintermantel, G. Lochead +2
Signatures of self-organized criticality (SOC) have recently been observed in an ultracold atomic gas under continuous laser excitation to strongly-interacting Rydberg states [S. H…
Controlling excitation avalanches in driven Rydberg gases
Kai Klocke, Michael Buchhold
Recent experiments with strongly interacting, driven Rydberg ensembles have introduced a promising setup for the study of self-organized criticality (SOC) in cold atom systems. Bas…
Thermalization Dynamics of Two Correlated Bosonic Quantum Wires After a Split
Sebastian Huber, Michael Buchhold, Jörg Schmiedmayer +1
Coherently splitting a one-dimensional Bose gas provides an attractive, experimentally estab- lished platform to investigate many-body quantum dynamics. At short enough times, the…
Dissipative Dicke Model with Collective Atomic Decay: Bistability, Noise-Driven Activation and Non-Thermal First Order Superradiance Transition
Jan Gelhausen, Michael Buchhold
The Dicke model describes the coherent interaction of a laser-driven ensemble of two level atoms with a quantized light field. It is realized within cavity QED experiments, which i…
Non-equilibrium effective field theory for absorbing state phase transitions in driven open quantum spin systems
Michael Buchhold, Benjamin Everest, Matteo Marcuzzi +2
Phase transitions to absorbing states are among the simplest examples of critical phenomena out of equilibrium. The characteristic feature of these models is the presence of a fluc…
Quantum-optical magnets with competing short- and long-range interactions: Rydberg-dressed spin lattice in an optical cavity
Jan Gelhausen, Michael Buchhold, Achim Rosch +1
The fields of quantum simulation with cold atoms [1] and quantum optics [2] are currently being merged. In a set of recent pathbreaking experiments with atoms in optical cavities […
Many-Body Quantum Optics with Decaying Atomic Spin States: (, ) Dicke model
Jan Gelhausen, Michael Buchhold, Philipp Strack
We provide a theory for quantum-optical realizations of the open Dicke model with internal, atomic spin states subject to spontaneous emission with rate . This introduces a seco…
Prethermalization and Thermalization of a Quenched Interacting Luttinger Liquid
Michael Buchhold, Markus Heyl, Sebastian Diehl
We study the relaxation dynamics of interacting, one-dimensional fermions with band curvature after a weak quench in the interaction parameter. After the quench, the system is desc…
Kinetic Theory for Interacting Luttinger Liquids
Michael Buchhold, Sebastian Diehl
We derive a closed set of equations for the kinetics and non-equilibrium dynamics of interacting Luttinger Liquids with cubic resonant interactions. In the presence of these intera…
Non-Equilibrium Universality in the Heating Dynamics of Interacting Luttinger Liquids
Michael Buchhold, Sebastian Diehl
We establish a new non-equilibrium scaling regime in the short time evolution of one-dimensional interacting open quantum systems subject to a generic heating mechanism. This dynam…
Quasi-Particle Theory for the Higgs Amplitude Mode
Ulf Bissbort, Michael Buchhold, Walter Hofstetter
We present a generalized quasi-particle theory for bosonic lattice systems, which naturally contains all relevant collective modes, including the Higgs amplitude in the strongly co…
Dicke Quantum Spin and Photon Glass in Optical Cavities: Non-equilibrium theory and experimental signatures
Michael Buchhold, Philipp Strack, Subir Sachdev +1
In the context of ultracold atoms in multimode optical cavities, the appearance of a quantum-critical glass phase of atomic spins has been predicted recently. Due to the long-range…
Correlated Topological Phases and Exotic Magnetism with Ultracold Fermions
Peter P. Orth, Daniel Cocks, Stephan Rachel +3
Motivated by the recent progress in engineering artificial non-Abelian gauge fields for ultracold fermions in optical lattices, we investigate the time-reversal-invariant Hofstadte…
Time-Reversal-Invariant Hofstadter-Hubbard Model with Ultracold Fermions
Daniel Cocks, Peter P. Orth, Stephan Rachel +3
We consider the time-reversal-invariant Hofstadter-Hubbard model which can be realized in cold atom experiments. In these experiments, an additional staggered potential and an arti…
