DOI: 10.1088/1367-2630/ac0e55

Abstract: We predict a repulsive Casimir–Polder-type dispersion interaction between a single neutron and a metal or dielectric surface. We consider a scenario where a single neutron is subject to an external magnetic field. Due to its… read more here.

DOI: 10.1088/1555-6611/ac458e

Abstract: In this paper, we study the dynamical Casimir–Polder force between an ensemble of identical two-level atoms and the wall of a rectangle waveguide with semi-infinite length. With the presence of both the rotating wave and… read more here.

DOI: 10.1103/physreva.101.052115

Abstract: We derive upper and lower bounds on the Casimir--Polder force between an anisotropic dipolar body and a macroscopic body separated by vacuum via algebraic properties of Maxwell's equations. These bounds require only a coarse characterization… read more here.

DOI: 10.1103/physreva.96.062504

Abstract: We consider Casimir-Polder and Casimir forces with finite dissipation by coupling heat baths to the dipoles introducing, this way, dissipation from 'first principles'. We derive a representation of the free energy as an integral over… read more here.

DOI: 10.1126/sciadv.aao4223

Abstract: We tailor the atom-surface Casimir-Polder interaction of cesium atoms using near-infrared surface plasmons of a metamaterial. Metamaterials are fascinating tools that can structure not only surface plasmons and electromagnetic waves but also electromagnetic vacuum fluctuations.… read more here.
