Dual-circular Raman optical activity of axial multipolar order
Hikaru Watanabe, Rikuto Oiwa, Hitoshi Mori +1
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 re…
Electric toroidal octupolar symmetry in pyrite FeS probed by Raman optical activity
Yuki Suganuma, Gakuto Kusuno, Hikaru Watanabe +4
We report Raman optical activity in pyrite FeS, which hosts an electric toroidal octupolar symmetry. A clear and reproducible sign reversal of the circular intensity difference…
Electron-phonon vertex correction effect in superconducting H3S
Shashi B. 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 electronic Fermi energy excee…
IsoME: Streamlining High-Precision Eliashberg Calculations
Eva Kogler, Dominik Spath, Roman Lucrezi +5
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 approx…
