Hyperbolic Spin Waves in Magnetic Polar Metals
Abhishek Kumar, Premala Chandra, Pavel A. Volkov
We demonstrate the emergence of collective spin modes with hyperbolic dispersion in three-dimensional spin-orbit coupled polar metals magnetized by intrinsic ordering or applied fi…
Observation of an electronic microemulsion phase emerging from a quantum crystal-to-liquid transition
Jiho Sung, Jue Wang, Ilya Esterlis +14
Strongly interacting electronic systems possess rich phase diagrams resulting from the competition between different quantum ground states. A general mechanism that relieves this f…
Topological Superconductivity in Twisted Flakes of Nodal Superconductors
Kevin P. Lucht, J. H. Pixley, Pavel A. Volkov
Twisted bilayers of nodal superconductors have been recently demonstrated to be a potential platform to realize two-dimensional topological superconductivity. Here we study the top…
"Quantum bipolaron" superconductivity from quadratic electron-phonon coupling
Zhaoyu Han, Steven A. Kivelson, Pavel A. Volkov
When the electron-phonon coupling is quadratic in the phonon coordinates, electrons can pair to form bipolarons due to phonon zero-point fluctuations, a purely quantum effect. We s…
Josephson diode effects in twisted nodal superconductors
Pavel A. Volkov, Étienne Lantagne-Hurtubise, Tarun Tummuru +3
Recent Josephson tunneling experiments on twisted flakes of high- cuprate superconductor BiSrCaCuO revealed a non-reciprocal behavior of the critical inter…
Phonon-Induced Collective Modes in Spin-Orbit Coupled Polar Metals
Abhishek Kumar, Premala Chandra, Pavel A. Volkov
We study the interplay between collective electronic and lattice modes in polar metals in an applied magnetic field aligned with the polar axis. Static spin-orbit coupling leads to…
