Inverse cascades and resonant triads in rotating and stratified turbulence
(American Institute of Physics, 2017-11)
Kraichnan’s seminal ideas on inverse cascades yielded new tools to study common phenomena in geophysical turbulent flows. In the atmosphere and the oceans, rotation and stratification result in a flow that can be approximated ...
Nonclassical effects in a highly nonlinear generalized homogeneous Dicke model
(Academic Press Inc Elsevier Science, 2011-09)
An intensity dependent nonlinear coupling model of N two-level atoms (generalized Dicke model) interacting dispersively with a bimodal cavity field via two-photon transitions is investigated in a scenario where the rotating ...
Thermal phase transition for some spin-boson models
(2013-09-01)
In this work we study two different spin-boson models. Such models are generalizations of the Dicke model, it means they describe systems of N identical two-level atoms coupled to a single-mode quantized bosonic field, ...

Quasi-exactly solvable approach to the Jaynes-Cummings model without rotation wave approximation
(2001)
The Jaynes-Cummings model (JCM) is studied in the frame of methods of quasi-exactly solvable problems. First, we apply these methods to the JCM under RWA and anti-RWA approximations and then, we analyze the possibility of ...

Inverse cascades in rotating stratified turbulence: Fast growth of large scales
(IOP Publishing, 2013-05)
We examine the inverse cascade of kinetic energy to large scales in rotating stratified turbulence as occurs in the oceans and in the atmosphere, while varying the relative frequency of gravity to inertial waves, N/f. Using ...
Global Magnetohydrodynamic Waves in Stably Stratified Rotating Layers
(University of Leeds UK, 2017-08-23)
The 2D shallow water approximation in magnetohydrodynamics is solved, numerically
and analytically, for a perfectly conducting fluid on a rotating sphere with a basic state
for the toroidal magnetic field: Bφ = B0 sin ...
Resonance expansion versus the rotating-wave approximation
(2003)
An effective Hamiltonian describing interaction between two subsystems beyond the standard RWA was found. This effective Hamiltonian has the form of a series of resonances. All the possible resonance transitions that can ...
