Field Dependence of Electronic Specific Heat in Two-Band Superconductors
Noriyuki Nakai, Masanori Ichioka, Kazushige Machida
The vortex structure is studied in light of MgB theoretically based on a two-band superconducting model by means of Bogoliubov-de Gennes framework. The field dependence of the…
Phonon anomalies due to stripe collective modes in high T_c cuprates
Eiji Kaneshita, Masanori Ichioka, Kazushige Machida
Phonon anomalies observed in various high cuprates by neutron experiments are analyzed theoretically in terms of the stripe concept. The phonon self-energy correction is eval…
Vortex structure in chiral p-wave superconductors
Mitsuaki Takigawa, Masanori Ichioka, Kazushige Machida +1
We investigate the vortex structure in chiral p-wave superconductors by the Bogoliubov-de Gennes theory on a tight-binding model. We calculate the spatial structure of the pair pot…
Vortex phase diagram in trapped Bose-Einstein condensation
Takeshi Mizushima, Tomoya Isoshima, Kazushige Machida
The vortex phase diagram in the external rotation frequency versus temperature is calculated for dilute Bose-Einstein condensed gases. It is determined within the Bogoliubov-Popov…
