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…
A general method to construct mean field counter diabatic driving for a ground state search
Hiroshi Hayasaka, Takashi Imoto, Yuichiro Matsuzaki +1
The counter diabatic (CD) driving has attracted much attention for suppressing non-adiabatic transition in quantum annealing (QA). However, it can be intractable to construct the C…
Quantum annealing showing an exponentially small success probability despite a constant energy gap with polynomial energy
Hiroshi Hayasaka, Takashi Imoto, Yuichiro Matsuzaki +1
Quantum annealing (QA) is a method for solving combinatorial optimization problems. We can estimate the computational time for QA using the adiabatic condition. The adiabatic condi…
Weak anti-localization in spin-orbit coupled lattice systems: effect of non-adiabatic transitions and estimation of spin relaxation length
Hiroshi Hayasaka
This study investigates the quantum correction effect on electrical conductivity using a two-dimensional Wolff Hamiltonian, which is an effective model of the spin-orbit coupling (…
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…
