Thermoelectric Effect in Mott Variable-Range Hopping
Takahiro Yamamoto, Masao Ogata, Hidetoshi Fukuyama
On the basis of the Kubo-Luttinger linear response theory combined with the scaling theory of Anderson localization predicting the energy dependence of localization length near the…
Nodal-line semimetal HMTSF-TCNQ: Anomalous orbital diamagnetism and charge density wave
S. Ozaki, I. Tateishi, H. Matsuura +2
This study investigates the electronic states and physical quantities of an organic charge-transfer complex HMTSF-TCNQ, which undergoes a charge-density-wave (CDW) phase transition…
Magnetic Switching by Oxygen Adsorption in Metal-Organic Framework Systems
Masaki Kato, Kunio Tokushuku, Hiroyasu Matsuura +2
In this letter, we address magnetization switching by oxygen adsorption in porous metal-organic framework systems. To this end, we construct a simple localized spin model combined…
Theory of Phason Drag Effect on Thermoelectricity
Hidetoshi Fukuyama, Masao Ogata
Lee, Rice and Anderson, in their monumental paper, have proved the existence of a collective mode describing the coupled motion of electron density and phonons in one-dimensional i…
Electric Transport of Nodal Line Semimetal in Single-Component Molecular Conductor
Yoshikazu Suzumura, Reizo Kato, Masao Ogata
We examine an effect of acoustic phonon scattering on an electric conductivity of single-component molecular conductor [Pd(dddt)] (dddt = 5,6-dihydro-1,4-dithiin-2,3-dithiolate…
Energy Landscape of Charge Excitations in Boundary Region between Dimer-Mott and Charge Order State in Molecular Solids
Hidetoshi Fukuyama, Jun-ichiro Kishine, Masao Ogata
A possible theoretical scheme is proposed for the unified description of charge excitations with orders of magnitude difference in energy [from optical(eV) down to…
