Superfluidity of charged Bose gas and bipolar mechanism of superconductivity

We show that a composite-field (diatom) Goldstone state is expected in a dilute Bose gas for temperatures between the Bose gas critical temperature where the atom Bose-Einstein condensate appears and the temperature where superfluidity sets in. The presence of superfluidity is tied to the existence of a U(1) charge-two diatom condensate in the system. By promoting the global U(1) symmetry of the theory to a gauge symmetry, we find that the mass of the gauge particle generated through the Anderson-Higgs mechanism is related to the superfluid density via the Meissner effect, and the superfluid density is related to the square of the anomalous density in the Bose system.We show that a composite-field (diatom) Goldstone state is expected in a dilute Bose gas for temperatures between the Bose gas critical temperature where the atom Bose-Einstein condensate appears and the temperature where superfluidity sets in.

Phase Diagram of a Charged Bose Gas

J. P. Hansen, B. Jancovici, Daniel Schiff

The phase diagram of a charged Bose gas is drawn. We discuss the domains of existence of the solid, fluid, and superfluid phases. It is predicted that superdense helium can be superfluid at densities higher than ${10}^{6}$ ${\mathrm{g}/\mathrm{c}\mathrm{m}}^{3}$ .The phase diagram of a charged Bose gas is drawn.

Bose-Einstein Condensation in a Dilute Atomic Vapor

David R. Lide

This chapter describes the National Bureau of Standards’ (NBS) Bose-Einstein Condensation (BEC) in a Dilute Atomic Vapor , relating the context in which the publication appeared, its impact on science, technology, and the general public, and brief details about the lives and work of the author. The first successful creation of dilute-gas BEC, announced in the NIST publication Observation of Bose-Einstein Condensation in a Dilute Atomic Vapor , was both a natural continuation of a 75-year tradition of NBS pre-eminence in spectroscopy and a striking confirmation that present-day NIST research is at the cutting edge of modern technology. The scientific motivation to create and study BEC in a gas stemmed from the long-held belief that the mechanism underlying BEC is the same mechanism responsible for the mysterious effects of superconductivity and superfluidity. Much of the standards and metrology work that NIST is charged with performing relies on precise spectroscopy of various internal resonances in atoms.This chapter describes the National Bureau of Standards’ (NBS) Bose-Einstein Condensation (BEC) in a Dilute Atomic Vapor , relating the context in which the publication appeared, its impact on science, technology, and the general public, and brief details about the lives and work of the author.
