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…
Multipartite entanglement and purity dynamics in classical channels influenced by fractional Gaussian noise
Muhammad Javed, Atta Ur Rahman, Lionel Tenemeza Kenfack +1
The dynamical map of entanglement and mixedness in four-qubit maximally entangled GHZ state paired with classical channels driven by fractional Gaussian noise is investigated. The…
On decoherence induced by a spin chain: role of initial prepared states
L. T. Kenfack, M. R. T. Fokou, M. Tchoffo +2
We study the decoherence process induced by a spin chain environment on a central spin consisting of R spins and we apply it on the dynamics of quantum correlations (QCs) of three…
Dynamics of entanglement and state-space trajectories followed by a system of four-qubit in the presence of random telegraph noise: common environment (CE) versus independent environments (IEs)
L. T. Kenfack, M. Tchoffo, M. N. Jipdi +2
The paper investigates the dynamics of entanglement and explores some geometrical characteristics of the trajectories in state space, in four-qubit Greenberger-Horne-Zeilinger (GHZ…
