Magneto-electric cooling rate of a multiferroic antiferromagnetic quantum spin system: the cumulative influence of the site-dependent magnetic and electric fields
William Degaulle Waladi Gueagni, Lionel Tenemeza Kenfack, Martin Tchoffo +2
The magneto-electrocaloric effect which can be defined as the coupling between magnetocaloric and electrocaloric effects attracts currently considerable attention due to the advant…
Periodically Driven Three-Level Systems
M. B. Kenmoe, L. C. Fai
We study the dynamics of a three-level system (ThLS) sinusoidally driven in both longitudinal and transverse directions and in the presence of a uniaxial anisotropy entering th…
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…
