Anisotropic contribution to the van der Waals and the Casimir-Polder energies for CO2 and CH4 molecules near surfaces and thin film
(Journal article; Peer reviewed, 2015)In order to understand why carbon dioxide ( CO 2 ) and methane ( CH 4 ) molecules interact differently with surfaces, we investigate the Casimir-Polder energy of a linearly polarizable CO 2 molecule and an isotropically ... -
Casimir force and its relation to surface tension
(Journal article; Peer reviewed, 2017)From energy considerations there is reason to expect that the work done by Casimir forces during a slow displacement of the parallel plates reflects the free energy of the surface tension of the adjacent surfaces. We show ... -
Casimir force between a half-space and a plate of finite thickness
(Journal article; Peer reviewed, 2016)Zero-frequency Casimir theory is analyzed from different viewpoints, with the aim of obtaining further insight into the delicate Drude-plasma issue that turns up when one considers thermal corrections to the Casimir force. ... -
Nonperturbative theory for the dispersion self-energy of atoms
(Journal article; Peer reviewed, 2014)We go beyond the approximate series expansions used in the dispersion theory of finite-size atoms. We demonstrate that a correct, and nonperturbative, theory dramatically alters the dispersion self-energies of atoms. The ... -
Presence of negative entropies in Casimir interactions
(Journal article; Peer reviewed, 2016)Negative entropy in connection with the Casimir effect at uniform temperature is a phenomenon rooted in the circumstance that one is describing a nonclosed system, or only part of a closed system. In this paper we show ...
