### On the pairing theory of the bose superfluid

- Physics
- 1969

SummaryIn analogy to the BCS theory of superconductivity, a self-consistent pairing theory of the Bose superfluid is developed along lines closely resembling the original Bose pairing model of…

### Thermodynamics of a trapped Bose-condensed gas

- Physics
- 1997

We investigate the thermodynamic behaviour of a Bose gas interacting with repulsive forces and confined in a harmonic anisotropic trap. We develop the formalism of mean field theory for non uniform…

### Excitation Spectrum and Thermodynamic Properties of Liquid He 4

- Physics
- 1969

Hohenberg and Martin (1) have pointed out that the theory of liquid helium has been developed on three different levels. We have already discussed two of these levels, the first being the…

### SPECIAL ISSUE: Bose-Einstein condensation in magnetic traps. Introduction to the theory

- Physics
- 1998

The recent realization of Bose–Einstein condensation in atomic gases opens new possibilities for the observation of macroscopic quantum phenomena. There are two important features of these systems —…

### On the microscopic derivation of the two-fluid thermohydrodynamic equations for4He II

- Physics
- 1972

The equivalence of the set of hydrodynamic equations for the macroscopic quantities associated with the4He II condensate and noncondensate—the natural parameters which occur in an O.D.L.R.O.-based…
