Dynamical symmetry approach and topological field theory for path integrals of quantum spin systems
Matous Ringel, Vladimir Gritsev
We develop a dynamical symmetry approach to path integrals for general interacting quantum spin systems. The time-ordered exponential obtained after the Hubbard-Stratonovich transf…
Full counting statistics of photons interacting with emitter
Mikhail Pletyukhov, Matouš Ringel, Vladimir Gritsev
A complete characterization of quantum fluctuations in many-body systems is accessible through the full counting statistics. We present an exact computation of statistical properti…
Liouville coherent states
Matouš Ringel, Vladimir Gritsev
For a certain class of open quantum systems there exists a dynamical symmetry which connects different time-evolved density matrices. We show how to use this symmetry for dynamics…
Replica-symmetry breaking: discrete and continuous schemes in the Sherrington-Kirkpatrick model
V Janis, A. Klic, M. Ringel
We study hierarchies of replica-symmetry-breaking solutions of the Sherrington-Kirkpatrick model. Stationarity equations for order parameters of solutions with an arbitrary number…
