Observations of Quantum Hall Effect and Inter-Band Effects of Magnetic fields on Hall Conductivity in Organic Massless Dirac Fermion System -(BETS)I under Pressure
K. Iwata, A. Koshiba, Y. Kawasugi +2
We investigated the magnetoresistance and the Hall effect in an organic massless Dirac fermion system -(BETS)I under pressure. The Fermi energy of this system is slightl…
Evidence for three-dimensional Dirac semimetal state in strongly correlated organic quasi-two-dimensional material
Naoya Tajima, Yoshitaka Kawasugi, Takao Morinari +3
The three-dimensional Dirac semimetal is distinct from its two-dimensional counterpart due to its dimensionality and symmetry. Here, we observe that molecule-based quasi-two-dimens…
Coherent interlayer coupling in quasi-two-dimensional Dirac fermions in -(BEDT-TTF)I
Naoya Tajima, Yoshitaka Kawasugi, Takao Morinari +3
Theoretical and experimental studies have supported that the electronic structure of -(BEDT-TTF)I under pressure is described by two-dimensional Dirac fermions. When the…
Chasing the spin gap through the phase diagram of a frustrated Mott insulator
A. Pustogow, Y. Kawasugi, H. Sakurakoji +1
The quest for entangled spin excitations has stimulated intense research on frustrated magnetic systems. For almost two decades, the triangular-lattice Mott insulator -(BEDT-TTF…
Narrow Zero Mode in Organic Massless Dirac Electron System -(BEDT-TTF)I
A. Mori, Y. Kawasugi, R. Doi +4
We investigated the interlayer magnetoresistance in an organic massless Dirac electron system -(BEDT-TTF)I under pressure. We experimentally demonstrate that the width o…
Pressure-induced phase switching of the Shubnikov de Haas oscillations in molecular Dirac fermion system (BETS)I
Yoshitaka Kawasugi, Hikaru Masuda, Masashi Uebe +4
We report on the Shubnikov de Haas (SdH) oscillations in the quasi two-dimensional molecular conductor (BETS)I [BETS: bis(ethylenedithio)tetraselenafulvalene] lamin…
