Pauli Paramagnetic Effects on Vortices in Superconducting TmNi2B2C
L. DeBeer-Schmitt, M. R. Eskildsen, M. Ichioka +6
The magnetic field distribution around the vortices in TmNi2B2C in the paramagnetic phase was studied experimentally as well as theoretically. The vortex form factor, measured by s…
Vortex states in superconductors with strong Pauli-paramagnetic effect
Masanori Ichioka, Kazushige Machida
Using the quasiclassical theory, we analyze the vortex structure of strong-paramagnetic superconductors.There, induced paramagnetic moments are accumulated exclusively around the v…
Is Sr2RuO4 a triplet superconductor?
K. Machida, M. Ichioka
The field dependence of the specific heat γ(H) at lower temperatures in Sr2RuO4 is analyzed by solving microscopic Eilenberger equation numerically. We find that systematic γ(H) be…
Imbalanced Superfluid Phase of a Trapped Fermi Gas in the BCS-BEC Crossover Regime
T. Mizushima, M. Ichioka, K. Machida
We theoretically investigate the ground state of trapped neutral fermions with population imbalance in the BCS-BEC crossover regime. On the basis of the single-channel Hamiltonian,…
Vortex state in a Fulde-Ferrell-Larkin-Ovchinnikov superconductor based on the quasiclassical theory
Masanori Ichioka, Hiroto Adachi, Takeshi Mizushima +1
We investigate the vortex state with Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) modulations suggested for a high field phase of CeCoIn_5. On the basis of the quasiclassical Eilenberge…
Quasi-Classical Calculation of the Mixed-State Thermal Conductivity in s-Wave and d-Wave Superconductors
Hiroto Adachi, Predrag Miranovic, Masanori Ichioka +1
To see how superconducting gap structures affect the longitudinal component of mixed-state thermal conductivity kappa_{xx}(B), the magnetic-field dependences of kappa_{xx}(B) in s-…
