Stability of the density-wave state of a dipolar condensate in a pancake trap
O. Dutta, R. Kanamoto, P. Meystre
We study a dipolar boson-fermion mixture in a pancake geometry at absolute zero temperature, generalizing our previous work on the stability of polar condensates and the formation…
Fermionic stabilization and density-wave ground state of a polar condensate
O. Dutta R. Kanamoto, P. Meystre
We examine the stability of a trapped dipolar condensate mixed with a single-component fermion gas at T=0. Whereas pure dipolar condensates with small s-wave interaction are unstab…
Topological Winding and Unwinding in Metastable Bose-Einstein Condensates
Rina Kanamoto, Lincoln D. Carr, Masahito Ueda
Topological winding and unwinding in a quasi-one-dimensional metastable Bose-Einstein condensate are shown to be manipulated by changing the strength of interaction or the frequenc…
Quantum dynamics of Raman-coupled Bose-Einstein condensates using Laguerre-Gaussian beams
Rina Kanamoto, Ewan M. Wright, Pierre Meystre
We investigate the quantum dynamics of Raman-coupled Bose-Einstein condensates driven by laser beams that carry orbital angular momentum. By adiabatically eliminating the excited a…
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…
Critical fluctuations in a soliton formation of attractive Bose-Einstein condensates
Rina Kanamoto, Hiroki Saito, Masahito Ueda
We employ mean-field, Bogoliubov, and many-body theories to study critical fluctuations in position and momentum of a Bose-Einstein condensate whose translation symmetry is spontan…
