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…
Quantum Phase Transition in Organic Massless Dirac Fermion System -(BEDT-TTF)I under pressure
Y. Unozawa, Y. Kawasugi, M. Suda +6
We investigate the effect of strong electronic correlation on the massless Dirac fermion system, -(BEDT-TTF)I, under pressure. In this organic salt, one can control the…
Universal Behavior of Magnetoresistance in Organic Dirac Electron Systems
Ryotaro Kobara, Shin Igarashi, Yoshitaka Kawasugi +7
In-plane magnetoresistance for organic massless Dirac electron system (OMDES) -(BEDT-TTF)I and -(BEDT-TTF)I in addition to possible candidates of the OMDES $α…
