Beyond the rotating wave approximation. An intensity dependent nonlinear coupling model in two-level systems
(Elsevier Science, 2010-03)
An intensity dependent nonlinear coupling model of a two-level system interacting with a bimodal cavity field via two-photon transitions is investigated in a scenario where the rotating wave approximation is lifted. The ...
Quantum bits and superposition of displaced fock states of the cavity field

The breaking of transience inertio-gravity waves in a shear flow using the Gaussian beam approximation.
(Cambridge University Press, 2014-11)
The propagation of transient inertio-gravity waves in a shear flow is examined using the Gaussian beam formulation. This formulation assumes Gaussian wavepackets in the spectral space and uses a second-order Taylor expansion ...

Plasma Waves Around Massive Stars in (3+1)-General Relativistic Magnetohydrodynamics
(2022-06-01)
In this article, the propagation of plasma waves around rotating and non-rotating stars is studied in a TPM (Thorne-Price-Macdonald) (3+1)-general relativistic magnetohydrodynamics (GRMHD) formalism. For more simplicity, ...
Quantifying resonant and near-resonant interactions in rotating turbulence
(Cambridge University Press, 2016-11)
Nonlinear triadic interactions are at the heart of our understanding of turbulence. In flows where waves are present, modes must not only be in a triad to interact, but their frequencies must also satisfy an extra condition: ...
The Euler equations in the columnar and rotational approximation: A model equation for asymptotic short capillary-gravity waves
(2002-01-01)
From a columnar approximation of the Euler equations of an incompressible fluid with surface tension, we derive in the short-wave approximation a new classical 1+1 dimensional model equation for the motion of the surface. ...

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 ...
