Generalized Chern numbers based on open system Green's functions
M. Belén Farias, Solofo Groenendijk, Thomas L. Schmidt
We present an alternative approach to studying topology in open quantum systems, relying directly on Green's functions and avoiding the need to construct an effective non-Hermitian…
Kerr effect in tilted nodal loop semimetals
Johan Ekström, Eddwi H. Hasdeo, M. Belén Farias +1
We investigate the optical activity of tilted nodal loop semimetals. We calculate the full conductivity matrix for a band structure containing a nodal loop with possible tilt in th…
Quantum friction in the Hydrodynamic Model
Kunmin Wu, Thomas L. Schmidt, M. Belén Farias
We study the phenomenon of quantum friction in a system consisting of a polarizable atom moving at a constant speed parallel to a metallic plate. The metal is described using a cha…
Casimir force between Weyl semimetals in a chiral medium
M. Belén Farias, Alexander A. Zyuzin, Thomas L. Schmidt
We study the Casimir effect in a system composed of two Weyl semimetals (WSMs) separated by a gap filled with a chiral medium. We calculate the optical response of the material to…
Motion induced radiation and quantum friction for a moving atom
M. Belen Farias, C. D. Fosco, Fernando C. Lombardo +1
We study quantum dissipative effects that result from the non-relativistic motion of an atom, coupled to a quantum real scalar field, in the presence of a static imperfect mirror.…
Dissipation and decoherence effects on a moving particle in front of a dielectric plate
M. Belén Farias, Fernando C. Lombardo
On this work, we consider a particle moving in front of a dielectric plate, and study two of the most relevant effects of the vacuum field fluctuations: the dissipation, and the de…
