Observation of classical to quantum crossover in electron glass
Hideaki Murase, Shunto Arai, Takuro Sato +4
Glass, a ubiquitous state of matter like a frozen liquid, is a seminal issue across fundamental and applied sciences and has long been investigated in the framework of classical me…
Charge and spin interplay in a molecular-dimer-based organic Mott insulator
Natalia Drichko, Shiori Sugiura, Minoru Yamashita +8
Triangular lattice quasi-two-dimensional Mott insulators based on BEDT-TTF molecule and its analogies present a possibility to produce exotic phases by coupling charge and spin deg…
Ferromagnetism out of charge fluctuation of strongly correlated electrons in -(BEDT-TTF)Hg(SCN)Br
Minoru Yamashita, Shiori Sugiura, Akira Ueda +10
We perform magnetic susceptibility and magnetic torque measurements on the organic -(BEDT-TTF)Hg(SCN)Br, which is recently suggested to host an exotic quantum dipole-liq…
Antiferromagnetic ordering in organic conductor -(BEDT-TTF)GaCl probed by C NMR
Yohei Saito, Shuhei Fukuoka, Takuya Kobayashi +2
The ground state of -(BEDT-TTF)GaCl, which has the same structure as the organic superconductor -(BETS)GaCl, was investigated by magnetic susceptibility and $…
Quantum-disordered state of magnetic and electric dipoles in a hydrogen-bonded Mott system
M. Shimozawa, K. Hashimoto, A. Ueda +12
Strongly enhanced quantum fluctuations often lead to a rich variety of quantum-disordered states. A representative case is liquid helium, in which zero-point vibrations of the heli…
Crystallization and vitrification of electrons in a glass-forming charge liquid
S. Sasaki, K. Hashimoto, R. Kobayashi +14
Charge ordering (CO) is a phenomenon in which electrons in solids crystallize into a periodic pattern of charge-rich and charge-poor sites owing to strong electron correlations. Th…
Optical Conductivity Measurement of a Dimer-Mott to Charge-Order Phase Transition in a Two-Dimensional Quarter-Filled Organic Salt Compound
Ryuji Okazaki, Yuka Ikemoto, Taro Moriwaki +7
We report a novel insulator-insulator transition arising from the internal charge degrees of freedom in the two-dimensional quarter-filled organic salt beta-(meso-DMBEDT-TTF)2PF6.…
Anisotropy of upper critical field in one-dimensional organic system, (TMTTF)PF under extremely high pressure
Mika Kano, Hatsumi Mori, Toshikazu Nakamura +6
We have measured the temperature dependent resistivity of (TMTTF)PF to 7 GPa using a turnbuckle DAC (diamond anvil cell) and in magnetic field up to 5 T. Unlike many other…
Superconductivity in the vicinity of charge ordered state in organic conductor beta-(meso-DMBEDT-TTF)_2PF_6
K. Yoshimi, M. Nakamura, H. Mori
We study theoretically competition between the charge ordering and the superconductivity in two-dimensional organic conductor beta-(meso-DMBEDT-TTF)_2PF_6. We analyze the extended…
Growth, structure analysis and anisotropic superconducting properties of MgB2 single crystals
S. Lee, H. Mori, T. Masui +3
Here we report the growth of sub-millimeter MgB2 single crystals of various shapes under high pressure in Mg-B-N system. Structure refinement using a single-crystal X-ray diffracti…
