Approach to equilbrium in nano-scale systems at finite temperatur
Approach to equilbrium nano-scale systems finite temperatur
2010/10/13
We study the time evolution of the reduced density matrix of a system of spin-1/2 particles interacting with an environment of spin-1/2 particles. The initial state of the composite system is taken to...
Effective Width and Expansion Energy of the Interacting Condensed 87Rb Bose Gas with Finite Size Effects
Interacting Bose gas Thermodynamical properties for BEC Semiclassical approach
2008/3/30
This work is devoted to study the temperature dependence of the effective width and expansion energy on the finite size and interaction effects (repulsive interactions). It is found that the effective...
Casimir energy of a dilute dielectric ball with uniform velocity of light at finite temperature
Casimir energy of a dilute dielectric ball uniform velocity of light finite temperature
2000/1/1
The Casimir energy, free energy and Casimir force are evaluated,at arbitrary finite temperature, for a dilute dielectric ball with uniform velocity of light inside the ball and in the surrounding medi...
Adiabatic Output Coupling of a Bose Gas at Finite Temperatures
Adiabatic Coupling Bose Gas Finite Temperatures
2000/1/1
We develop a general theory of adiabatic output coupling from trapped, weakly-interacting,
atomic Bose-Einstein Condensates at finite temperatures. For weak coupling, the output rate from the condens...
