Variable Mass Quantum Harmonic Oscillator; Exact Solvability and Isospectral Potentials

M. Tchoffo, M. Vubangsi & L. C. Fai · Physical Science International Journal · 2014

By imposing a particular constraint of solvability on the Liouville normal form of the BenDaniel-Duke type variable mass Schr¨odinger equation, we have derived a class of solvable potentials and harmonic oscillator type solutions for the system. The method has been shown to be ap...

Decoherence Induced by a Quenching Driven Field on the Motion of a Single Electron

L. C. Fai, M. Tchoffo, J. T. Diffo & G. C. Fouokeng · Physical Science International Journal · 2013

We investigate the motion of an electron in a one dimensional crystal coupled to an EMF potential, driven by an external force which is continuously switched on and off. The Shannon entropy and the thermodynamic parameters of the system are evaluated using the density matrix and...
