Bragg spectroscopy of a cigar shaped Bose condensate in optical lattices
Tarun Kanti Ghosh, Kazushige Machida
We study properties of excited states of an array of weakly coupled quasi-two-dimensional Bose condensates by using the hydrodynamic theory. We calculate multibranch Bogoliubov-Blo…
Vortex Core Structure in Neutral Fermion Superfluids with Population Imbalance
M. Takahashi, T. Mizushima, M. Ichioka +1
Quantized vortex core structure is theoretically investigated in Fermion superfluids with population imbalance for two atom species of neutral atom clouds near a Feshbach resonance…
Ubiquitous V-shape density of states in mixed state of clean limit type II superconductors; STM experiment and theory
N. Nakai, P. Miranovic, M. Ichioka +6
It is demonstrated theoretically and experimentally that the low energy density of states is described by a singular V-shape form for all clean sup…
Surface and vortex structures in noncentrosymmetric superconductors under applied magnetic fields
Masatosi Oka, Masanori Ichioka, Kazushige Machida
We investigate how the macroscopic spatial structure of broken inversion symmetry manifests in noncentrosymmetric superconductors, by the microscopic broken inversion symmetry of t…
Specific heat and low-lying excitations in the mixed state for a type II superconductor
N. Nakai, P. Miranovic, M. Ichioka +1
Low temperature behavior of the electronic specific heat in the mixed state is by the self-consistent calculation of the Eilenberger theory. In addition to -term ( is…
Cyclic phase in F=2 spinor condensate: Long-range order, kinks, and roughening transition
W. V. Pogosov, K. Machida
We study the effect of thermal fluctuations on homogeneous infinite Bose-Einstein condensate with spin F=2 in the cyclic state, when atoms occupy three hyperfine states with $m_{F}…
