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. ... -
Numerical studies of the scattering of light from a two-dimensional randomly rough interface between two dielectric media
(Journal article; Peer reviewed, 2016)The scattering of polarized light incident from one dielectric medium on its two-dimensional randomly rough interface with a second dielectric medium is studied. A reduced Rayleigh equation for the scattering amplitudes ... -
Numerical studies of the transmission of light through a two-dimensional randomly rough interface
(Journal article; Peer reviewed, 2017)The transmission of polarized light through a two-dimensional randomly rough interface between two dielectric media has been much less studied, by any approach, than the reflection of light from such an interface. We have ... -
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 ... -
Probing phase separation in Bose-Fermi mixtures by the critical superfluid velocity
(Journal article; Peer reviewed, 2010)We investigate the effect exerted by spin-polarized fermions on the interaction between superfluid bosons for a Bose-Fermi mixture residing on an optical lattice, with particular emphasis on the possibility of an induced ... -
Superfluidity breakdown and multiple roton gaps in spin-orbit-coupled Bose-Einstein condensates in an optical lattice
(Journal article, 2014)We investigate the superfluid phases of a Rashba spin-orbit-coupled Bose-Einstein condensate residing on a two-dimensional square optical lattice in the presence of an effective Zeeman field Ω. At a critical value Ω=Ωc, ...
