Abstract CaFeAsF is an iron-based superconductor parent compound whose Fermi surface is quasi-two dimensional, composed of Dirac-electron and Schrödinger-hole cylinders elongated along the c axis. We measured the longitudinal and Hall resistivities

Theoretical and experimental studies have supported that the electronic structure of $\alpha$-(BEDT-TTF)$_2$I$_3$ under pressure is described by two-dimensional Dirac fermions. When the interlayer tunneling is coherent, the electronic structure of th

We investigate the effect of strong electronic correlation on the massless Dirac fermion system, $\alpha$-(BEDT-TTF)$_2$I$_3$, under pressure. In this organic salt, one can control the electronic correlation by changing pressure and access the quantu

The magnetic molecular conductor λ-(BETS)2FeCl4 shows metal–insulator (MI) transition and antiferromagnetic (AF) transition simultaneously at TMI ~ 8.3 K. In its metallic phase, two Fermi surfaces coexist, and the one has good nesting, and the oth

Motivated by the metal–insulator transition in layered organic compound λ-(BETS)2FeCl4, where naive theoretical calculations predict metallic phase after the antiferromagnetic transition, we propos...

In most Dirac semimetals, time-reversal and inversion symmetries are believed to play a crucial role in their stability. We demonstrate that these symmetries are broken in Dirac fermions in the organic conductor $\alpha$-(BEDT-TTF)$_2$I$_3$ due to th

We report the effect of Dirac cone tilting on interlayer magnetoresistance in \alpha-(BEDT-TTF)$_2$I$_3$, which is a Dirac semimetal under pressure. Fitting of the experimental data by the theoretical formula suggests that the system is close to a ty

The central issue in high-temperature cuprate superconductors is the pseudogap state appearing below the pseudogap temperature $T^*$, which is well above the superconducting transition temperature. In this study, we theoretically investigate the rapi
