An inequality for spinor Bose-Einstein condensates

Daisuke A. Takahashi

An inequality for spin- Bose-Einstein condensates (BECs) is reported, where , , and represent the density, singlet…

Hetero pairing and component-dependent pseudogap phenomena in an ultracold Fermi gas with mass imbalance

Ryo Hanai, Yoji Ohashi

We investigate the superfluid phase transition and single-particle excitations in the BCS (Bareen-Cooper-Schrieffer)-BEC (Bose-Einstein condensation) crossover regime of an ultraco…

Pseudogap phenomena in a two-dimensional ultracold Fermi gas near the Berezinskii-Kosterlitz-Thouless transition

M. Matsumoto, Y. Ohashi

We investigate single-particle excitations and strong-coupling effects in a two-dimensional Fermi gas. Including pairing fluctuations within a Gaussian fluctuation theory, we calcu…

Counting rule of Nambu-Goldstone modes for internal and spacetime symmetries: Bogoliubov theory approach

Daisuke A. Takahashi, Muneto Nitta

When continuous symmetry is spontaneously broken, there appear Nambu-Goldstone modes (NGMs) with linear and quadratic dispersion relations, which are called type-I and type-II, res…

Green's function formalism for a condensed Bose gas consistent with infrared-divergent longitudinal susceptibility and Nepomnyashchii-Nepomnyashchii identity

Shohei Watabe, Yoji Ohashi

We present a Green's function formalism for an interacting Bose-Einstein condensate (BEC) satisfying the two required conditions: (i) the infrared-divergent longitudinal susceptibi…
