Dual-Circular Raman Optical Activity of Axial Multipolar Order

Anonymous, Rikuto Oiwa, Hitoshi Mori, Ryotaro Arita

Multipolar order, such as octupolar order, is a key concept in condensed matter physics, particularly in light of elusive hidden orders. However, its experimental identification remains challenging due to the absence of direct coupling to conventional external stimuli. In this Letter, we …

Valley-dependent electron-phonon scattering in thermoelectric semimetal Ta 2 PdSe 6

Masayuki Ochi, Hitoshi Mori, Akitoshi Nakano

Quasi-one-dimensional transition-metal chalcogenide Ta$_2$PdSe$_6$ is a promising thermoelectric semimetal due to the strong electron-hole asymmetry in the carrier lifetime. However, the microscopic origin of such a strong asymmetry remains unclear. In this study, we theoretically investigate electron-phonon scattering in Ta$_2$PdSe$_6$. There is …

Electric toroidal octupolar symmetry in pyrite FeS$_2$ probed by Raman optical activity

Yuki Suganuma, Gakuto Kusuno, Hikaru Watanabe, Rikuto Oiwa et autres

We report Raman optical activity in pyrite FeS$_2$, which hosts an electric toroidal octupolar symmetry. A clear and reproducible sign reversal of the circular intensity difference is observed between neighboring $\{111\}$ faces under cross-circular polarization. The signal appears only for the doubly …

Electron–phonon vertex correction effect in superconducting H3S

Shashi Bhusan Mishra, Hitoshi Mori, Elena R. Margine

The Migdal–Eliashberg (ME) formalism provides a reliable framework for describing phonon-mediated superconductivity in the adiabatic regime, where the Fermi energy exceeds the characteristic phonon energy. Here, we extend this framework by incorporating first-order vertex corrections to the electron–phonon (e–ph) interaction and evaluating …

IsoME: Streamlining high-precision Eliashberg calculations

Eva Kogler, Dominik Spath, Roman Lucrezi, Hitoshi Mori et autres

This paper introduces the Julia package IsoME , an easy-to-use yet accurate and robust computational tool designed to calculate superconducting properties. Multiple levels of approximation are supported, ranging from the basic McMillan-Allen-Dynes formula and its machine learning-enhanced variant to Eliashberg theory, including …

Efficient anisotropic Migdal-Eliashberg calculations with an intermediate representation basis and Wannier interpolation

Hitoshi Mori, Takuya Nomoto, Ryotaro Arita, Elena R. Margine

In this study, we combine the ab initio Migdal-Eliashberg approach with the intermediate representation of the Green's function, enabling accurate and efficient calculations of the momentum-dependent superconducting gap function while fully considering the effect of the Coulomb retardation. Unlike the conventional scheme …

1999 年伊豆大島における人工地震探査 : 観測および初動走時データによる3 次元地震波速度構造

Hidefumi Watanabe, Tsuneomi Kagiyama, Shikou Sakashita, Jun Oikawa et autres

Seismic exploration at Izu-Oshima volcano was conducted from the end of October to the beginning of November, 1999. We deployed 256 temporary seismic stations and fired six artificial sources with dynamite. We carefully picked the first motions from the seismograms to obtain …
