Ultrasonic Observation of Slowing Down of Multipole Fluctuations in SrRuO
Ryosuke Kurihara, Mitsuhiro Akatsu, Shunsuke Yaoita +5
We performed ultrasonic measurements on the unconventional superconductor SrRuO to investigate the dynamical properties of the electronic states near its superconducting tr…
Elastic Soft Mode and Electric Quadrupole Response in Excitonic Insulator Candidate (TaV)NiSe: Contribution of Electron-Phonon Interaction
Ryosuke Kurihara, Yusuke Hirose, Sumika Sano +4
We performed ultrasonic measurements on (TaV)NiSe to investigate the contribution of acoustic phonons at the zone center to structural and possible exci…
Critical Slowing Down of Quadrupole and Hexadecapole Orderings in Iron Pnictide Superconductor
Ryosuke Kurihara, Keisuke Mitsumoto, Mitsuhiro Akatsu +4
Ultrasonic measurements have been carried out to investigate the critical dynamics of structural and superconducting transitions due to degenerate orbital bands in iron pnictide co…
The role of hyperfine coupling in magnetic and quadrupolar ordering of Pr3Pd20Si6
Lucia Steinke, Keisuke Mitsumoto, Corneliu F. Miclea +8
We study the ternary clathrate Pr3Pd20Si6 in specific heat and AC-susceptibility measurements on a high-quality single crystal, distinguishing antiferromagnetic (AFM) and antiferro…
Cooperative Effect of Coulomb Interaction and Electron-Phonon Coupling on the Heavy Fermion State in the Two-Orbital Periodic Anderson Model
Keisuke Mitsumoto, Yoshiaki Ono
We investigate the two-orbital periodic Anderson model, where the local orbital fluctuations of f-electrons couple with a two-fold degenerate Jahn-Teller phonon, by using the dynam…
Phonon softening and double-well potential formation due to electron-phonon interaction in heavy-fermion systems
Keisuke Mitsumoto, Yoshiaki Ono
We investigate the periodic Anderson-Holstein model by using the dynamical mean-field theory combined with the exact diagonalization method. For the strong electron-phonon coupling…
