Solvable model for pair excitation in trapped Boson gas at zero temperature
Solvable model pair excitation trapped Boson gas zero temperature
2015/10/16
In Bose–Einstein condensation (BEC), particles occupy a single-particle quantum state, , macroscopically. At zero temperature, the wavefunction for is usually described via a nonlinear Schrodinger ...
A bound from below for the temperature in compressible Navier-Stokes equations
below for the temperature compressible Navier-Stokes equations
2015/10/15
We consider the full system of compressible Navier-Stokes equations for heat conducting fluid. We show that the temperature is uniformly positive for t ≥ t0 (for any t0 > 0) for any solutions with fin...
Dissipative dynamics in semiconductors at low temperature
Dissipative dynamics semiconductors low temperature Functional Analysis
2011/8/26
Abstract: A mathematical model is introduced which describes the dissipation of electrons in lightly doped semi-conductors. The dissipation operator is proved to be densely defined and positive and to...
Finite-temperature nonlinear dynamics in cavity QED: A Thermofield Dynamics Approach
cavity QED Finite-temperature nonlinear dynamics Thermofield Dynamics Approach
2011/7/7
Heath-bath effects in the dynamics of atom + cavity system are studied. The temperature effects are explored using thermofield dynamics formalism. It is found that the dynamics of the system is sensit...
Methods of exploring energy diffusion in lattices with finite temperature
lattices energy diffusion finite temperature
2011/7/7
We discuss two methods for exploring energy diffusion in lattices with finite temperature in this paper. The first one is the energy-kick (EK) method. To apply this method, one adds an external energy...
Towards a unified characterization of phenological phases: fluctuations and correlations with temperature
Biological Physics (physics.bio-ph) Adaptation and Self-Organizing Systems (nlin.AO) Data Analysis, Statistics and Probability (physics.data-an)
2010/11/11
Phenological timing -- i.e. the course of annually recurring development stages in nature -- is of particular interest since it can be understood as a proxy for the climate at a specific region; moreo...
Long-distance behavior of temperature correlation functions in the one-dimensional Bose gas

2010/11/19
We describe a Bethe ansatz based method to derive, starting from a multiple integral representation, the long-distance asymptotic behavior at finite temperature of the density-density correlation fun...
