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…

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…
