Phonon-induced collective modes in spin-orbit coupled polar metals
Source abstract
Abstract
In spin-orbit coupled metals, polar phonons couple to the spin of electrons by inducing a dynamical Rashba-type spin splitting. Here, the authors study the consequences of such coupling in polar metals, where one of the polar phonons has undergone a symmetry-breaking transition. They show that application of magnetic field reveals a spectrum of collective modes that can change their character (electronic vs. lattice) and energy as a function of field strength. Optical spectroscopy experiments are shown to have the capability to probe these modes.
