Quasi-Nambu-Goldstone Modes in Bose-Einstein Condensates

Shun Uchino, Michikazu Kobayashi, Muneto Nitta +1

We show that quasi-Nambu-Goldstone (NG) modes, which play prominent roles in high energy physics but have been elusive experimentally, can be realized with atomic Bose-Einstein con…

Superfluid density of states and pseudogap phenomenon in the BCS-BEC crossover regime of a superfluid Fermi gas

Ryota Watanabe, Shunji Tsuchiya, Yoji Ohashi

We investigate single-particle excitations and strong-coupling effects in the BCS-BEC crossover regime of a superfluid Fermi gas. Including phase and amplitude fluctuations of the…

Topological Excitations in Spinor Bose-Einstein Condensates

Yuki Kawaguchi, Michikazu Kobayashi, Muneto Nitta +1

A rich variety of order parameter manifolds of multicomponent Bose-Einstein condensates (BECs) admit various kinds of topological excitations, such as fractional vortices, monopole…

Superfluid/ferromagnet/superfluid junction and -phase in a superfluid Fermi gas

Takashi Kashimura, Shunji Tsuchiya, Yoji Ohashi

We investigate the possibility of superfluid/ferromagnet/superfluid (SFS)-junction in a superfluid Fermi gas. To examine this possibility in a simple manner, we consider an attract…

Analogues of D-branes in Bose-Einstein condensates

Kenichi Kasamatsu, Hiromitsu Takeuchi, Muneto Nitta +1

We demonstrate theoretically that analogues of D-branes in string theory can be realized in rotating, phase-separated, two-component Bose-Einstein condensates and that they are obs…

Photoemission spectrum and effect of inhomogeneous pairing fluctuations in the BCS-BEC crossover regime of an ultracold Fermi gas

Shunji Tsuchiya, Ryota Watanabe, Yoji Ohashi

We investigate the photoemission-type spectrum in a cold Fermi gas which was recently measured by JILA group [J. T. Stewart {\it et al}., Nature \textbf{454}, 744 (2008)]. This qua…
