Rotational Quantum Friction via Spontaneous Decay
Nicolas Schüler, O. J. Franca, Michael Vaz +2
A fascinating effect belonging to the field of vacuum forces and fluctuations is that of quantum friction. It refers to the prediction of a dissipative force acting on a moving obj…
Purcell effect in chiral environments
C. S. Rapp, Janine C. Franz, S. Y. Buhmann +1
The Purcell effect describes the modification of the spontaneous decay rate in the presence of electromagnetic media and bodies. In this work, we shed light on the dependencies and…
Spectroscopic footprints of quantum friction in nonreciprocal and chiral media
O. J. Franca, Fabian Spallek, Steffen M. Giesen +4
We investigate how the quantum friction experienced by a polarizable atom moving with constant velocity parallel to a planar interface is modified when the latter consists of chira…
Vavilov-Cherenkov radiation for parallel motion in three-dimensional topological insulators
O. J. Franca, Stefan Yoshi Buhmann
Our study delves into the modifications observed in Vavilov-Cherenkov radiation when its generating charged particle moves parallel to an interface formed by two generic magnetoele…
