Ultrafast creation of overlapping Rydberg electrons in an atomic BEC and Mott-insulator lattice
Michiteru Mizoguchi, Yichi Zhang, Masaya Kunimi +13
An array of ultracold atoms in an optical lattice (Mott insulator) excited to a state where single electron wave-functions spatially overlap would represent a new and ideal platfor…
Nonequilibrium steady states of Bose-Einstein condensates with a local particle loss in double potential barriers
Masaya Kunimi, Ippei Danshita
We investigate stability of non-equilibrium steady states of Bose-Einstein condensates with a local one-body loss in the presence of double potential barriers. We construct an exac…
Upper bound of one-magnon excitation and lower bound of effective mass for ferromagnetic spinor Bose and Fermi gases
Masaya Kunimi, Hiroki Saito
Using a variational method, we derive an exact upper bound for one-magnon excitation energy in ferromagnetic spinor gases, which limits the quantum corrections to the effective mas…
Energy shift of magnons in a ferromagnetic spinor-dipolar Bose-Einstein condensate
Hiroki Saito, Masaya Kunimi
Motivated by the recent experiment performed by the Berkeley group [G. E. Marti {\it et al.}, Phys. Rev. Lett. {\bf 113}, 155302 (2014)], we consider the dynamics of magnons in a s…
