Tight-Binding Model and Electronic Property of Dirac Nodal Line in Single-Component Molecular Conductor [Pt(dmdt)]
Taiki Kawamura, Daigo Ohki, Biao Zhou +2
Motivated by the recent discovery of Dirac nodal line in the single-component molecular conductor [Pt(dmdt)], we propose a three-orbital tight-binding model based on the Wann…
Possible Spin-Density Wave on Fermi Arc of Edge State in Single-Component Molecular Conductors [Pt(dmdt)] and [Ni(dmdt)]
Taiki Kawamura, Biao Zhou, Akiko Kobayashi +1
We construct three-orbital tight-binding models describing single-component molecular conductors [Pt(dmdt)] and [Ni(dmdt)] using first-principles calculations. We show that…
Impact of impurity scattering on odd-frequency spin-triplet pairing near the edge of the Kitaev chain
Sparsh Mishra, Shun Tamura, Akito Kobayashi +1
We study a Kitaev chain model, which is the simplest model of topological superconductors hosting Majorana fermion, appearing as a zero-energy state at the edge. We analytically ca…
Transport properties of organic Dirac electron system α-(BEDT-TSeF)I
Daigo Ohki, Kazuyoshi Yoshimi, Akito Kobayashi
Motivated by the insulating behavior of -(BEDT-TSeF)I at low temperatures ('s), we first performed first-principles calculations based on the crystal structural data…
Effect of Coulomb Interaction on Seebeck Coefficient of Organic Dirac Electron System -(BEDT-TTF)I
Daigo Ohki, Yukiko Omori, Akito Kobayashi
Motivated by the results of recent thermoelectric effect studies, we show the effects of Coulomb interactions on the Seebeck coefficient based on an extended Hubbard model that des…
