Simple model of the wave pattern in the atmosphere of a slow rotating planet due to surface irregularities
(Pergamon-Elsevier Science Ltd, 2020-05)
Recent observations show a persistent pattern on Venus surface, interpreted as a stationary wave due to the interaction of the prevailing winds with the orography of the planet. In this work we use an idealized model of ...
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 ...
Vortices in Bose-Einstein condensates with dominant dipolar interactions
(American Physical Society, 2009-06)
We present full three-dimensional numerical calculations of single vortex states in rotating dipolar condensates. We consider a Bose-Einstein condensate of C 52 r atoms with dipole-dipole and s -wave contact interactions ...
Dual constant-flux energy cascades to both large scales and small scales
(American Institute of Physics, 2017-11)
In this paper, we present an overview of concepts and data concerning inverse cascades of excitation towards scales larger than the forcing scale in a variety of contexts, from two-dimensional fluids and wave turbulence ...
Positronium ionization by short UV laser pulses: Splitting of the ATI peaks by Rabi oscillations
(Elsevier Science, 2006-12)
The interaction between positronium and a short laser pulse is studied in the case, where the photon energy is resonant with the 1s → 2p transition energy. Results from a full numerical solution of the time-dependent ...
Period-doubling and Hopf bifurcations in far-infrared driven quantum well intersubband transitions
(American Physical Society, 2003-07)
The behavior of n-δ-doped wide quantum well (QW) heterostructures in the presence of intense far-infrared (FIR) radiation is studied using the semiconductor Bloch equations, in the time-dependent Hartree version and without ...
On quadrupole and octupole gravitational radiation in the ANK formalism
(Springer/Plenum Publishers, 2017-04-23)
Following the approach of Adamo–Newman–Kozameh (ANK) we derive the equations of motion for the center of mass and intrinsic angular moment for isolated sources of gravitational waves in axially symmetric spacetimes. The ...
Jaynes-Cummings model under monochromatic driving
(American Physical Society, 2020-09)
We study analytically and numerically the properties of the Jaynes-Cummings model under monochromatic driving. The analytical results allow us to understand the regime of two branches of multiphoton excitation in the case ...
Optimization of X-ray tube voltage to improve the precision of two phase flow meters used in petroleum industry
