Ambient-Pressure Organic Dirac Electron State in -(BETS)AuCl
Takuya Kobayashi, Kazuyoshi Yoshimi, Aoto Nishimoto +2
We report an ambient-pressure Dirac electron (DE) state in a new organic conductor, -(BETS)AuCl (BETS = bis(ethylenedithio)tetraselenafulvalene). This salt exhibits char…
Pressure-induced topological changes in Fermi surface of two-dimensional molecular conductor
T. Kobayashi, K. Yoshimi, H. Ma +5
We demonstrated X-ray structural analysis of the pressure-induced superconductor, -ETICl under extremely high-pressure conditions, where ET denotes bis(ethylenedithio)t…
Surface structure of the 3x3-Si phase on Al(111), studied by the multiple usages of positron diffraction and core-level photoemission spectroscopy
Yusuke Sato, Yuki Fukaya, Akito Nakano +13
The structure of an Al(111)3x3-Si surface was examined by combining data from positron diffraction and core-level photoemission spectroscopy. Analysis of the diffraction rocking cu…
Pressure-induced nearly perfect rectangular lattice and superconductivity in an organic molecular crystal (DMET-TTF)AuBr
Taiga Kato, Hanming Ma, Kazuyoshi Yoshimi +13
External pressure and associated changes in lattice structures are key to realizing exotic quantum phases such as high- superconductivity. While applying external pressu…
Sub-photon accuracy noise reduction of single shot coherent diffraction pattern with atomic model trained autoencoder
Takuto Ishikawa, Yoko Takeo, Kai Sakurai +8
Single-shot imaging with femtosecond X-ray lasers is a powerful measurement technique that can achieve both high spatial and temporal resolution. However, its accuracy has been sev…
Combined X-ray diffraction, electrical resistivity, and study of (TMTTF)PF under pressure: implications to the unified phase diagram
Miho Itoi, Kazuyoshi Yoshimi, Hanming Ma +7
We present a combined experimental and theoretical study on the quasi-one-dimensional organic conductor (TMTTF)PF, and elucidate the variation of its physical properties un…
Compressed Sensing of Compton Profiles for Fermi Surface Reconstruction: Concept and Implementation
J. Otsuki, K. Yoshimi, Y. Nakanishi-Ohno +3
Compton scattering is a well-established technique that can provide detailed information about electronic states in solids. Making use of the principle of tomography, it is possibl…
Multipolar ordering from dynamical mean field theory with application to CeB6
J. Otsuki, K. Yoshimi, H. Shinaoka +1
Magnetic and multipolar ordering in f electron systems takes place at low temperatures of order 1--10 Kelvin. Combinations of first-principles with many-body calculations for such…
