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…
Introducing the notion of tensors through a variation of a Feynman didactic approach
Lucas Queiroz, Edson C. M. Nogueira, Danilo T. Alves
In one of his books [, vol. 2], Feynman presents a didactic approach to introduce basic ideas about tensors, using, as a first example, t…
