Quantum kinetic Ising models
R. Augusiak, F. M. Cucchietti, F. Haake +1
We introduce a quantum generalization of classical kinetic Ising models, described by a certain class of quantum many body master equations. Similarly to kinetic Ising models with…
Decoherence bypass of macroscopic superpositions in quantum measurement
D. Spehner, F. Haake
We study a class of quantum measurement models. A microscopic object is entangled with a macroscopic pointer such that a distinct pointer position is tied to each eigenvalue of the…
Photocount statistics of chaotic lasers
G. Hackenbroich, C. Viviescas, B. Elattari +1
We derive the photocount statistics of the radiation emitted from a chaotic laser resonator in the regime of single-mode lasing. Random spatial variations of the resonator eigenfun…
Frobenius-Perron Resonances for Maps with a Mixed Phase Space
Joachim Weber, Fritz Haake, Petr Seba
Resonances of the time evolution (Frobenius-Perron) operator P for phase space densities have recently been shown to play a key role for the interrelations of classical, semiclassi…
Superradiant Laser: First-Order Phase Transition and Non-stationary Regime
Christian Wiele, Fritz Haake, Kazimierz Rzazewski
We solve the superradiant laser model in two limiting cases. First the stationary low-pumping regime is considered where a first-order phase transition in the semiclassical solutio…
Semiclassics for a Dissipative Quantum Map
Daniel Braun, Petr A. Braun, Fritz Haake
We present a semiclassical analysis for a dissipative quantum map with an area-nonpreserving classical limit. We show that in the limit of Planck's constant to 0 the trace of an ar…
