Unusual Low-Energy Collective Charge Excitations in High- Cuprate Superconductors
Vyacheslav M. Silkin, Stefan-Ludwig Drechsler, Dmitry V. Efremov
Despite decades of intensive experimental and theoretical efforts, the physics of cuprate high-temperature superconductors in general, and, in particular, their normal state, is st…
Peculiarities of electron transport and resistive switching in point contacts on TiSe2, TiSeS and CuxTiSe2
D. L. Bashlakov, O. E. Kvitnitskaya, S. Aswartham +5
TiSe2 has received much attention among the transition metals chalcogenides because of its thrilling physical properties concerning atypical resistivity behavior, emerging of charg…
Crystal growth, characterization and electronic band structure of TiSeS
Y. Shemerliuk, A. Kuibarov, O. Feia +8
Layered semimetallic van der Waals materials TiSe2 has attracted a lot of attention because of interplay of a charge density wave (CDW) state and superconductivity. Its sister comp…
Electron-phonon interaction and point contact enhanced superconductivity in trigonal PtBi2
D. L. Bashlakov, O. E. Kvitnitskaya, G. Shipunov +5
PtBi2 is a Weyl semimetal, which demonstrates superconductivity with low critical temperature Tc ~ 0.6 K in the bulk. Here, we report our study of electron-phonon interaction (EPI)…
Phase tunable second-order topological superconductor
S. Franca, D. V. Efremov, I. C. Fulga
Two-dimensional second-order topological superconductors (SOTSCs) have gapped bulk and edge states, with zero-energy Majorana bound states localized at corners. Motivated by recent…
Multicritical Fermi surface topological transitions
Dmitry V. Efremov, Alex Shtyk, Andreas W. Rost +3
A wide variety of complex phases in quantum materials are driven by electron-electron interactions, which are enhanced through density of states peaks. A well known example occurs…
