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…
Background Field Functional Renormalization Group for Absorbing State Phase Transitions
Michael Buchhold, Sebastian Diehl
We present a functional renormalization group approach for the active to inactive phase transition in directed percolation type systems, in which the transition is approached from…
Absorbing state phase transition with competing quantum and classical fluctuations
M. Marcuzzi, M. Buchhold, S. Diehl +1
Stochastic processes with absorbing states feature remarkable examples of non-equilibrium universal phenomena. While a broad understanding has been progressively established in the…
