Strain as a tool to stabilize the isotropic triangular lattice in a geometrically frustrated organic quantum magnet
Francisco Lieberich, Yohei Saito, Yassine Agarmani +5
Geometric frustration is a key ingredient in the emergence of exotic states of matter, such as the quantum spin liquid in Mott insulators. While there has been intense interest in…
Dimer-Mott and charge-ordered insulating states in the quasi-one-dimensional organic conductors - and -(BPDT-TTF)ICl
R. Kobayashi, K. Hashimoto, N. Yoneyama +7
We investigated the electronic states of the quasi-one-dimensional organic conductors -(BPDT-TTF)ICl and -(BPDT-TTF)ICl, both of which are insulatin…
Collective excitation of a short-range charge ordering in -$\mbox{(BEDT-TTF)}_2\mbox{CsZn(SCN)}_4$
K. Hashimoto, S. C. Zhan, R. Kobayashi +5
We find a characteristic low-energy peak structure located in the range of 100-300 cm in the optical conductivity spectra of a quasi-two-dimensional organic compound with a…
Phonon-Spectrum Narrowing Induced by Ultrafast Charge Fluctuation in an Organic Dimer Mott Insulator
K. Itoh, H. Itoh, S. Saito +7
We have observed the characteristic temperature dependence of the intermolecular phonon spectrum in the organic dimer Mott insulator kappa-(ET)2Cu2(CN)3 exhibiting a dielectric ano…
Collective excitation of electric dipole on molecular dimer in organic dimer-Mott insulator
K. Itoh, H. Itoh, M. Naka +6
The terahertz (THz) response in 10-100 cm^-1 was investigated in an organic dimer-Mott (DM) insulator kappa-(ET)_2Cu_2(CN)_3 that exhibits a relaxor-like dielectric anomaly. 30 cm^…
Relaxor ferroelectricity induced by electron correlations in a molecular dimer Mott insulator
S. Iguchi, S. Sasaki, N. Yoneyama +3
We have investigated the dielectric response in an antiferromagnetic dimer-Mott insulator beta'-(BEDT-TTF)2ICl2 with square lattice, compared to a spin liquid candidate kappa-(BEDT…
Suppression of superconductivity by non-magnetic disorder in organic superconductor -(BEDT-TTF)Cu(NCS)
T. Sasaki, H. Oizumi, Y. Honda +2
The suppression of superconductivity by nonmagnetic disorder is investigated systematically in the organic superconductor -(BEDT-TTF)Cu(NCS). We introduce a nonmagnetic…
Electron localization near Mott transition in organic superconductor -(BEDT-TTF)Cu[N(CN)Br
K. Sano, T. Sasaki, N. Yoneyama +1
The effect of disorder on the electronic properties near the Mott transition is studied in an organic superconductor -(BEDT-TTF)Cu[N(CN)]Br, which is systematically…
