Thermodynamic Properties of the Mott Insulator-Metal Transition in a Triangular Lattice System Without Magnetic Order
Emre Yesil, Shusaku Imajo, Satoshi Yamashita +5
The organic system, -[(BEDT-TTF)(BEDT-STF)]Cu(CN), showing the Mott transition between a nonmagnetic Mott insulating (NMI) state and a Fermi liquid (FL),…
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…
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 -[…
Extraordinary -Electron Superconductivity Emerging from a Quantum Spin Liquid
Shusaku Imajo, Shiori Sugiura, Hiroki Akutsu +6
Quantum spin liquids (QSLs), in which spins are highly entangled, have been considered a groundwork for generating exotic superconductivity.Despite numerous efforts, superconductiv…
Anisotropic Fully-Gapped Superconductivity Possibly Mediated by Charge Fluctuations in a Nondimeric Organic Complex
Shusaku Imajo, Hiroki Akutsu, Ryosuke Kurihara +5
We investigate low-temperature electronic properties of the nondimeric organic superconductor -(BEDT-TTF)[(HO)Ga(CO)]PhNO. By examining ul…
Effects of Electron Correlations and Chemical Pressures on Superconductivity of -type Organic Compounds
S. Imajo, H. Akutsu, A. Akutsu-Sato +3
We investigate low-temperature electronic states of the series of organic conductors -(BEDT-TTF)[(HO)M(CO)]G, where BEDT-TTF is bis(ethylenedi…
Fermi-surface topology and the effects of intrinsic disorder in a class of charge-transfer salts containing magnetic ions, β''-(BEDT-TTF)_4[(H_3O)M(C_2O_4)_3]Y
A. I. Coldea, A. F. Bangura, J. Singleton +5
We report high-field magnetotransport measurements on β''-(BEDT-TTF)_4[(H_3O)M(C_2O_4)_3]Y, where M=Ga, Cr and Fe and Y=C_5H_5N. We observe similar Shubnikov-de Haas oscillations i…
