Mottness and spin liquidity in a doped organic superconductor -(BEDT-TTF)HgBr
Hiroshi Oike, Hiromi Taniguchi, Kazuya Miyagawa +1
It has been more than 40 years since superconductivity was discovered in organic conductors, and the way scientists view organic superconductors has changed over time. At first, th…
Role of hydrogen bonding in charge-ordered organic conductor -(BEDT-TTF)I probed by I nuclear quadrupole resonance
T. Kobayashi, Y. Kato, H. Taniguchi +3
We present I nuclear quadrupole resonance spectra and nuclear relaxation of -(BEDT-TTF)I that undergoes a charge-ordering transition. Only one of the two I a…
Reduced superfluid density in a doped spin liquid candidate
K. Wakamatsu, Y. Ueno, K. Miyagawa +2
A quantum spin liquid (QSL) would be an exotic stage for superconductivity. A promising candidate for a doped QSL is the organic triangular-lattice system, kappa-(BEDT-TTF)4Hg2:89B…
Metal-insulator transition via control of spin liquidity in a doped Mott insulator
Hiroshi Oike, Kazuya Miyagawa, Hiromi Taniguchi +2
Quantum spin liquid states, in which spins are quantum-mechanically delocalized in direction, have been so far studied for charge-localized Mott insulators arising from strong repu…
Mott-driven BEC-BCS crossover in a doped spin liquid candidate, kappa-(BEDT-TTF)4Hg2.89Br8
Y. Suzuki, K. Wakamatsu, J. Ibuka +5
The pairing of interacting fermions leading to superfluidity has two limiting regimes: the Bardeen-Cooper-Schrieffer (BCS) scheme for weakly interacting degenerate fermions and the…
Antiferromagnetic ordering of organic Mott insulator -(BEDSe-TTF)GaCl
A. Ito, T. Kobayashi, D. P. Sari +6
The band structure and magnetic properties of organic charge-transfer salt -(BEDSe-TTF)GaCl (BEDSe-TTF: bis(ethylenediseleno)tetrathiafulvalene; abbreviated as -BEDSe…
