Phase-Space Methods for Simulating the Dissipative Many-Body Dynamics of Collective Spin Systems
Julian Huber, Peter Kirton, Peter Rabl
We describe an efficient numerical method for simulating the dynamics and steady states of collective spin systems in the presence of dephasing and decay. The method is based on th…
Emergence of PT-symmetry breaking in open quantum systems
Julian Huber, Peter Kirton, Stefan Rotter +1
The effect of PT-symmetry breaking in coupled systems with balanced gain and loss has recently attracted considerable attention and has been demonstrated in various photonic, elect…
Non-equilibrium magnetic phases in spin lattices with gain and loss
Julian Huber, Peter Kirton, Peter Rabl
We study the magnetic phases of a non-equilibrium spin chain, where coherent interactions between neighboring lattice sites compete with alternating gain and loss processes. This c…
Active energy transport and the role of symmetry breaking in microscopic power grid
Julian Huber, Peter Rabl
We study the transfer of energy through a network of coupled oscillators, which represents a minimalmicroscopic power grid connecting multiple active quantum machines. We evaluate…
