Quantized Hall conductance in graphene by nonperturbative magnetic-field-containing relativistic tight-binding approximation method
Md. Abdur Rashid, Masahiko Higuchi, Katsuhiko Higuch
In this study, we conducted a numerical investigation on the Hall conductance () of graphene based on the magnetic energy band structure calculated using a nonperturbativ…
Theoretical description of the first-order phase transition of aluminum from a superconducting to normal state by the current-density functional theory for superconductors
Katsuhiko Higuchi, Masahiko Higuchi
We show that the current-density functional theory for superconductors (sc-CDFT) can describe the magnetic-field-induced first-order phase transition of aluminum from a superconduc…
Second-order phase transition of silicon from a band insulator to metal induced by strong magnetic fields
Katsuhiko Higuchi, Dipendra Bahadur Hamal, Masahiko Higuchi
We present the second-order phase transition from a band insulator to metal that is induced by a strong magnetic field. The magnetic-field dependences of the magnetization and ener…
Current-Density Functional Theory for the superconductor
Katsuhiko Higuchi, Masahiko Higuchi
We present the current-density functional theory for the superconductor immersed in the magnetic field. The order parameter of the superconducting state, transverse component of th…
