Can Spinor Dipolar Effects be Observed in Bose-Einstein Condensates?
Yuki Kawaguchi, Hiroki Saito, Masahito Ueda
Weak dipolar effects in atomic Bose-Einstein condensates (BECs) have recently been predicted to develop spin textures. However, observation of these effects requires magnetic field…
Topological defect formation in quenched ferromagnetic Bose-Einstein condensates
Hiroki Saito, Yuki Kawaguchi, Masahito Ueda
We study the dynamics of the quantum phase transition of a ferromagnetic spin-1 Bose-Einstein condensate from the polar phase to the broken-axisymmetry phase by changing magnetic f…
Symmetry Breaking in Bose-Einstein Condensates
Masahito Ueda, Yuki Kawaguchi, Hiroki Saito +2
A gaseous Bose-Einstein condensate (BEC) offers an ideal testing ground for studying symmetry breaking, because a trapped BEC system is in a mesoscopic regime, and situations exist…
Jarzynski Equality with Maxwell's Demon
Takahiro Sagawa, Masahito Ueda
We propose a new thermodynamic equality and several inequalities concerning the relationship between work and information for an isothermal process with Maxwell's demon. Our approa…
Broken axisymmetry phase of a spin-1 ferromagnetic Bose-Einstein condensate
Keiji Murata, Hiroki Saito, Masahito Ueda
A spin-1 ferromagnetic Bose-Einstein condensate subject to a certain magnetic field exhibits a broken-axisymmetry phase in which the magnetization tilts against the applied magneti…
Spontaneous Circulation in Ground-State Spinor Dipolar Bose-Einstein Condensates
Yuki Kawaguchi, Hiroki Saito, Masahito Ueda
We report on a study of the spin-1 ferromagnetic Bose-Einstein condensate with magnetic dipole-dipole interactions. By solving the non-local Gross-Pitaevskii equations for this sys…
