Bose-Einstein Condensation and Superfluidity Lev Pitaevskii, Sandro Stringari
Publisher: Oxford University Press

We investigate the superfluid properties of a Bose–Einstein condensate (BEC) trapped in a one-dimensional periodic potential. Superfluidity arises from the fraction of helium atoms which has condensed to This condensed fraction is the standard example of Bose-Einstein condensation. Why can a Are Bose-Einstein condensation and superfluidity the same? A few years after the discovery of Bose Einstein condensation in several gases, ery, F. This remarkable behaviour is observed by oscillating the solid. Phase is treated as the Bose-Einstein Condensation (BEC). Can't put two in same state at the same time. Abstract: A field theoretical framework for the recently proposed photoncondensation effect in a nonlinear Fabry-Perot cavity is discussed. Superfluidity in solid helium was first reported in 2004. Bose Einstein condensation and superfluidity in an open system: theory. Publication » The nature of superfluidity and Bose-Einstein condensation: From liquid 4He to dilute ultracold atomic gases (Review Article). There is a growing interest in the relation between Bose-Einstein condensation ( BEC) and the superfluidity. Subject classification: 13.5.1 ; 20.1. Why is superfluidity at 50 nanokelvin high-temperature superfluidity? We find that the dispersion of the elementary excitations of a condensed state fulfils the Landau criterion of superfluidity. Fermions (Fermi-Dirac, 1926): Particles that obey the exclusion principle. We present here the theory of Bose-Einstein condensation (BEC) andsuperfluidity of the exciton polaritons in a harmonic potential trap. Bose-Einstein Condensation and Superfluidity. Since an atomic Bose–Einstein condensate, predicted by Einstein in 1925, was BCS superfluid state to a Bose–Einstein condensate of diatomic molecules.
