Nonequilibrium Casimir-Polder Force: Magnus-like Effect
Maria Vittoria Gurrieri, Kurt Busch, Francesco Intravaia
The motion of a particle in vacuum near macroscopic bodies gives rise to a Magnus-like contribution to the nonequilibrium Casimir-Polder force. This effect originates from the inte…
The Casimir-Polder interaction between atoms and hollow-core fibers
Bettina Beverungen, Daniel Reiche, Kurt Busch +1
The Casimir-Polder force acts on polarizable particles due to quantum fluctuations of the electromagnetic field that are modified by the presence of material bodies. We investigate…
Influence of random surface deformations on the resonance frequencies and quality factors of optical cavities and plasmonic nanoparticles
Philip Trøst Kristensen, Thomas Kiel, Kurt Busch +1
Surface deformations of optical cavities and plasmonic nanoparticles are inevitable in nanophotonics. The random morphology changes of different realizations modify the associated…
Numerical evaluation of Casimir forces using the discontinuous Galerkin time-domain method
Carles Martà Farrà s, Bettina Beverungen, Philip Trøst Kristensen +2
We present a time-domain scheme for computing Casimir forces within the Maxwell stress tensor formalism, together with a specific realization using the finite-element-based discont…
Nonequilibrium Casimir-Polder Force: Motion-induced Thermal-like Effect
D. Reiche, B. Beverungen, K. Busch +1
The Casimir-Polder force is analyzed when an atom is moving at a constant velocity relative to a collection of translationally invariant macroscopic bodies with generic shapes and…
The power-spectrum tensor in steady-state systems and its role in quantum friction
F. Intravaia, K. Busch
We derive and classify properties of the power-spectrum tensor for systems in general steady-states, including stationary states not necessarily corresponding to equilibrium config…
