Chiral Gain-Induced Time-Reversal Symmetry Breaking in Quantum Systems
Mário G. Silveirinha, Daigo Oue
Structured light offers a powerful approach to tailor light-matter interactions in quantum systems with chiral properties. While chirality has been extensively studied in passive p…
Quantum Friction near the Instability Threshold
Daigo Oue, Boris Shapiro, Mário G. Silveirinha
In this work, we develop an analytical framework to understand quantum friction across distinct stability regimes, providing approximate expressions for frictional forces both in t…
Stable-to-unstable transition in quantum friction
Daigo Oue, J. B. Pendry, Mário G. Silveirinha
We investigate the frictional force arising from quantum fluctuations when two dissipative metallic plates are set in a shear motion. While early studies showed that the electromag…
Spontaneous Symmetry Breaking of Time-Reversal-Symmetry and Time-Crystal States in Chiral Atomic Systems
Mário G. Silveirinha, Hugo Terças, Mauro Antezza
We present a theoretical study of the interaction between an atom characterized by a degenerate ground state and a reciprocal environment, such as a semiconductor nanoparticle, wit…
Impact of Chiral-Transitions in Quantum Friction
Muzzamal I. Shaukat, Mario G. Silveirinha
We theoretically investigate the role of chiral-transitions in the quantum friction force that acts on a two-level atom that moves with relative velocity v parallel to a planar met…
Fluctuational electrodynamics in and out of equilibrium
Iver Brevik, Boris Shapiro, Mário Silveirinha
Dispersion forces between neutral material bodies are due to fluctuations of the polarization of the bodies. For bodies in equilibrium these forces are often referred to as Casimir…
