Critical quasienergy states in driven many-body systems
Victor Manuel Bastidas, Georg Engelhardt, Pedro Perez-Fernandez +2
We discuss singularities in the spectrum of driven many-body spin systems. In contrast to undriven models, the driving allows us to control the geometry of the quasienergy landscap…
Quantum criticality and dynamical instability in the kicked top
V. M. Bastidas, P. Perez-Fernandez, M. Vogl +1
We investigate precursors of critical behavior in the quasienergy spectrum due to the dynamical instability in the kicked top. Using a semiclassical approach, we analytically obtai…
Equation of motion method for Full Counting Statistics: Steady state superradiance
Malte Vogl, Gernot Schaller, Eckehard Schöll +1
For the multi-mode Dicke model in a transport setting that exhibits collective boson transmissions, we construct the equation of motion for the cumulant generating function. Approx…
Counting statistics of collective photon transmissions
Malte Vogl, Gernot Schaller, Tobias Brandes
We theoretically study cooperative effects in the steady-state transmission of photons through a medium of radiators. Using methods from quantum transport, we find a cross-over…
The speed of Markovian relaxation towards the ground state
Malte Vogl, Gernot Schaller, Tobias Brandes
For sufficiently low reservoir temperatures, it is known that open quantum systems subject to decoherent interactions with the reservoir relax towards their ground state in the wea…
