Quantum Monte Carlo study of superfluid density in quasi-one-dimensional hard-core bosons: Effect of suppression of phase slippage
A. Masaki-Kato, S. Yunoki, D. S. Hirashima
We study the superfluid density of hard-core bosons on quasi-one-dimensional lattices using the quantum Monte Carlo method. Because of phase slippage, the superfluid density drops…
Spin Hall effect in iron-based superconductors: A Dirac-point effect
Sudhakar Pandey, Hiroshi Kontani, Dai S. Hirashima +2
We have theoretically explored the intrinsic spin Hall effect (SHE) in the iron-based superconductor family with a variety of materials. The study is motivated by an observation th…
Intrinsic Spin Hall Effect in s-wave Superconducting State: Analysis of Rashba Model
H. Kontani, J. Goryo, D. S. Hirashima
A general expression for the spin Hall conductivity (SHC) in the s-wave superconducting state at finite temperatures is derived. Based on the expression, we study the SHC in a two-…
Giant Orbital Hall Effect in Transition Metals: Origin of Large Spin and Anomalous Hall Effects
H. Kontani, T. Tanaka, D. S. Hirashima +2
In transition metals and their compounds, the orbital degrees of freedom gives rise to an orbital current, in addition to the ordinary spin and charge currents. We reveal that cons…
Spin Hall effect in Sr2RuO4 and transition metals (Nb,Ta)
T. Tanaka, H. Kontani, M. Naito +3
We study the intrinsic spin Hall conductivity (SHC) and the -orbital Hall conductivity (OHC) in metallic -electron systems based on the multiorbital tight-binding model. The…
Study of Intrinsic Spin Hall Effect and Orbital Hall Effect in 4d- and 5d- Transition Metals
T. Tanaka, H. Kontani, M. Naito +4
We study the intrinsic spin Hall conductivity (SHC) in various -transition metals (Ta, W, Re, Os, Ir, Pt, and Au) and 4d-transition metals (Nb, Mo, Tc, Ru, Rh, Pd, and Ag) base…
