A time-dependent harmonic oscillator with two frequency jumps: an exact algebraic solution
D. M. Tibaduiza, L. Pires, A. L. C. Rego +3
We consider a harmonic oscillator (HO) with a time dependent frequency which undergoes two successive abrupt changes. By assumption, the HO starts in its fundamental state with fre…
Efficient algebraic solution for a time-dependent quantum harmonic oscillator
D. M. Tibaduiza, L. B. Pires, D. Szilard +3
Using operator ordering techniques based on BCH-like relations of the su(1,1) Lie algebra and a time-splitting approach,we present an alternative method of solving the dynamics of…
Double-layer force suppression between charged microspheres
D. S. Ether, F. S. S. Rosa, D. M. Tibaduiza +3
In this paper we propose a protocol to suppress double-layer forces between two microspheres immersed in a dielectric medium, being one microsphere metallic at a controlled potenti…
Electrostatic Force Between Two Colloidal Spheres
Daniel Martínez Tibaduiza
In this dissertation we analyzed the double-layer force interaction between two dielectric charged colloidal spheres of different radii immersed in a solution of ions in water and…
