Correlation-driven organic 3D topological insulator with relativistic fermions
Tetsuya Nomoto, Shusaku Imajo, Hiroki Akutsu +2
Exploring new topological phenomena and functionalities induced by strong electron correlation has been a central issue in modern condensed-matter physics. One example is a topolog…
Novel quantum phase of the chromium spinel oxide HgCrO in high magnetic fields
Shojiro Kimura, Shusaku Imajo, Masaki Gen +4
In this study, we have performed the magnetocaloric effect and the specific heat measurements of chromium spinel oxide HgCrO, wherein the magnetic Cr ions form a hig…
Persistence of fermionic spin excitations through a genuine Mott transition in -type organics
Shusaku Imajo, Naoko Kato, Robert J. Marckwardt +3
We investigate the continuous variation of electronic states from a Fermi liquid to a quantum spin liquid induced by chemical substitution in the organic dimer-Mott system of -[…
Magnetically hidden state on the ground floor of the magnetic Devil's staircase
Shusaku Imajo, Naofumi Matsuyama, Toshihiro Nomura +10
We investigated the low-temperature and high-field thermodynamic and ultrasonic properties of SrCu2(BO3)2, which exhibits various plateaux in its magnetization curve above 27~T, ca…
Enhanced superconducting pairing strength near a nonmagnetic nematic quantum critical point
K. Mukasa, K. Ishida, S. Imajo +14
The quest for high-temperature superconductivity at ambient pressure is a central issue in physics. In this regard, the relationship between unconventional superconductivity and th…
