New orderings for effective mass Hamiltonians and associated wavefunction matching conditions at abrupt heterojunctions
Mercel Vubangsi, Martin Tchoffo, Lukong Cornelius Fai
We show that for a given setting of the Von Roos ambiguity parameters, it is not required that the Morrow and Brownstein condition be satisfied to achieve physically acceptable tra…

Dzyaloshinskii-Moriya interactions effects on the entanglement dynamics of a two qubit xxz spin system in non-Markovian environment
Georges Collince Fouokeng, Martin Tchoffo, Edwine Tendong +1
We investigate the exact entanglement dynamics of a two-qubit Heisenberg XXZ chain with Dzyaloshinskii-Moriya (DM) interactions, interacting with an anisotropic spin bath in therma…
