Comparison of analytical and numerical methods and the effect of bath coupling on the quantum decoherence
comparison analytical and numerical methods quantum decoherence
2010/11/8
The dynamics of a qubit in a structured environment is investigated theoretically. One point of view of the model is the spin-boson model with a Lorentz shaped spectral density. An alternative view is...
Analytical and numerical investigation of nonlinear internal gravity waves
Analytical and numerical investigation nonlinear internal gravity waves
2009/11/12
The propagation of long, weakly nonlinear internal waves in a stratified gas is studied. Hydrodynamic equations for an ideal fluid with the perfect gas law describe the atmospheric gas behaviour. If w...
Analytical and Numerical Study of a Barotropic Eddy on a Topographic Slope
Barotropic Eddy Topographic Slope Analytical and Numerical
2008/12/16
Using the nondivergent barotropic equation on an f plane, the evolution of an eddy placed on a topographic slope is studied. The theoretical analysis is in two pans. First, using the linearized equati...

Adomian decomposition Method；tanh -function Method；nonlinear Burgers' equation；analytical solution；accuracy
2008/11/10
In this paper, we present two methods for finding solutions to the one-dimensional nonlinear Burgers' equation. The first method is an analytical one, which is based on the tanh - function method. The...
Tidal Eulerian Residual Currents over a Slope: Analytical and Numerical Frictionless Models
Residual Currents Numerical Frictionless Models
2008/10/27
The Eulerian residual tidal currents generated over a continental slope are examined. Using the assumption of a Poincaré wave, the linear frictionless solution of a semidiurnal tidal wave propagating ...
