Gauge invariance, collective modes, and the justification of normal-state subtraction in Dirac superconductors
Hiroshi Hayasaka
In Dirac superconductors, the unbounded spectrum of low-energy Dirac models is known to give rise to unphysical interband contributions from deep-lying states to the electromagneti…

Weak anti-localization in spin-orbit coupled lattice systems
Hiroshi Hayasaka, Yuki Fuseya
The quantum correction to electrical conductivity is studied on the basis of two-dimensional Wolff Hamiltonian, which is an effective model for a spin-orbit coupled (SOC) lattice s…

Crystalline spin-orbit interaction and the Zeeman splitting in PbSnTe
Hiroshi Hayasaka, Yuki Fuseya
The ratio of the Zeeman splitting to the cyclotron energy (), which characterizes the relative strength of the spin-orbit interaction in crystals, is examined f…
