Curvature effects on the regimes of the lateral van der Waals force
Alexandre P. Costa, Lucas Queiroz, Danilo T. Alves
Recently, it has been shown that, under the action of the lateral van der Waals (vdW) force due to a perfectly conducting corrugated plane, a neutral anisotropic polarizable partic…
The time-dependent quantum harmonic oscillator: a pedagogical approach via the Lewis-Riesenfeld dynamical invariant method
Stanley S. Coelho, Lucas Queiroz, Danilo T. Alves
In quantum mechanics courses, students often solve the Schrödinger equation for the harmonic oscillator with time-independent parameters. However, time-dependent quantum harmonic o…
Influence of retardation and dispersive surfaces on the regimes of the lateral Casimir-Polder force
Lucas Queiroz
We investigate, by means of the scattering approach, the Casimir-Polder interaction between a neutral anisotropic polarizable particle and a corrugated surface made of a realistic…
Squeezing equivalence of quantum harmonic oscillators under different frequency modulations
Stanley S. Coelho, Lucas Queiroz, Danilo T. Alves
The papers by Janszky and Adam [Phys. Rev. A {\bf 46}, 6091 (1992)] and Chen \textit{et al.} [Phys. Rev. Lett. {\bf 104}, 063002 (2010)] are examples of works where one can find th…
Exact solution of a time-dependent quantum harmonic oscillator with two frequency jumps via the Lewis-Riesenfeld dynamical invariant method
Stanley S. Coelho, Lucas Queiroz, Danilo T. Alves
Harmonic oscillators with multiple abrupt jumps in their frequencies have been investigated by several authors during the last decades. We investigate the dynamics of a quantum har…
Sign inversion in the lateral van der Waals force between an anisotropic particle and a plane with a hemispherical protuberance: an exact calculation
Lucas Queiroz, Edson C. M. Nogueira, Danilo T. Alves
We investigate the lateral van der Waals (vdW) force between an anisotropic polarizable particle and a perfectly conducting plane with a hemispherical protuberance with radius .…
Curvature-induced repulsive effect on the lateral Casimir-Polder--van der Waals force
Danilo T. Alves, Lucas Queiroz, Edson C. M. Nogueira +1
We consider a perfectly conducting infinite cylinder with radius , and investigate the Casimir-Polder (CP) and van der Waals (vdW) interactions with a neutral polarizable partic…
Regimes of the lateral van der Waals force in the presence of dielectrics
Lucas Queiroz, Edson C. M. Nogueira, Danilo T. Alves
In a recent paper, it was shown that, under the action of the lateral van der Waals (vdW) force due to a perfectly conducting corrugated surface, a neutral anisotropic polarizable…
Sign inversion in the lateral van der Waals force
Edson C. M. Nogueira, Lucas Queiroz, Danilo T. Alves
We consider a single slight protuberance in a perfectly conducting plane, and investigate the van der Waals (vdW) interaction between this surface and a neutral polarizable particl…
Peak, valley and intermediate regimes in the lateral van der Waals force
Edson C. M. Nogueira, Lucas Queiroz, Danilo T. Alves
We study the van der Waals (vdW) interaction between a polarizable particle and a grounded conducting corrugated surface. For sinusoidal corrugations, one knows that, under the act…
