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…

Quantum order by disorder in Frustrated Spin Nanotubes

João C. Getelina, Zekun Zhuang, Premala Chandra +3

We investigate quantum order by disorder in a frustrated spin nanotube formed by wrapping a - Heisenberg model at 45 around a cylinder. Using Schwinger boson theo…

Dielectric relaxation by quantum critical magnons

Daniel Flavián, Pavel A. Volkov, Shohei Hayashida +4

We report the experimental observation of dielectric relaxation by quantum critical magnons. Complex capacitance measurements reveal a dissipative feature with a temperature-depend…

Light-Driven Transitions in Quantum Paraelectrics

Zekun Zhuang, Ahana Chakraborty, Premala Chandra +2

Motivated by recent experiments on pump-induced polar ordering in the quantum paraelectric SrTiO, we study a driven phonon system close to a second order phase transition. Anal…

Observation of a Critical Charge Mode in a Strange Metal

Hisao Kobayashi, Yui Sakaguchi, Hayato Kitagawa +12

Quantum electronic matter has long been understood in terms of two limiting behaviors of electrons: one of delocalized metallic states, and the other of localized magnetic states.…

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…
