Spin-Phonon Resonances in Nearly Polar Metals with Spin-Orbit Coupling
Abhishek Kumar, Premala Chandra, Pavel A. Volkov
In metals in the vicinity of a polar transition, interactions between electrons and soft phonon modes remain to be determined. Here we explore the consequences of spin-orbit assist…
Josephson effects in twisted nodal superconductors
Pavel A. Volkov, Shu Yang Frank Zhao, Nicola Poccia +3
Motivated by the recent proposals for unconventional emergent physics in twisted bilayers of nodal superconductors, we study the peculiarities of the Josephson effect at the twiste…
Emergent Interfacial Superconductivity between Twisted Cuprate Superconductors
S. Y. Frank Zhao, Nicola Poccia, Xiaomeng Cui +11
Twisted interfaces between stacked van der Waals cuprate crystals enable tunable Josephson coupling between in-plane anisotropic superconducting order parameters. Employing a novel…
Superconductivity from energy fluctuations in dilute quantum critical polar metals
Pavel A. Volkov, Premala Chandra, Piers Coleman
Superconductivity in low carrier density metals challenges the conventional electron-phonon theory due to the absence of retardation required to overcome Coulomb repulsion. In quan…
Failed excitonic quantum phase transition in TaNi(SeS)
Pavel A. Volkov, Mai Ye, Himanshu Lohani +3
We study the electronic phase diagram of the excitonic insulator candidates TaNi(SeS) [x=0, ... ,1] using Raman spectroscopy. Critical excitonic fluctuations ar…
Lattice dynamics of the excitonic insulator TaNi(SeS)
Mai Ye, Pavel A. Volkov, Himanshu Lohani +4
Recently, we employed electronic polarization-resolved Raman spectroscopy to reveal the strongly correlated excitonic insulator (EI) nature of Ta2NiSe5, Volkov et al. [arXiv:2007.0…
