Confinement-Tunable Synthetic Gauge Fields and Floquet Topological Phenomena in a Driven Quantum Wire Qubit
Feulefack Ornela Claire, Dongmo Tedo Lynsia Saychele, Danga Jeremie Edmond +6
Theoretical analysis indicates that a spin qubit in a parabolic quantum wire, when driven by a bichromatic field, generates a confinement-tunable non-Abelian synthetic gauge field…
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…
Landau-Zener transitions in a qubit periodically driven in both longitudinal and transverse directions
A. B. Tchapda, M. B. Kenmoe, A. D. Kammogne +1
We theoretically investigate the dynamics of a spin-qubit periodically driven in both longitudinal and transverse directions by two classical fields respectively a radio-frequency…
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…
Compared study of Shannon, Tsallis and Gaussian entropy of bound magnetopolaron in nanostructures
M. Tiotsop, A. J. Fotue, H. B. Fotsin +1
Many methods have been experimented to study decoherence in nanostructures. Tsallis, Shannon and Gaussian entropy have been used to study decoherence separately; in this paper, we…
SU(3) Landau-Zener interferometry with a transverse periodic drive
M. B. Kenmoe, A. B. Tchapda, L. C. Fai
Quantum triangles can work as interferometers. Depending on their geometric size and interactions between paths, "beats" {\it and/or} "steps" patterns are observed. We show that wh…
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…
Demkov-Kunike Models with Decay
M. B. Kenmoe, A. B. Tchapda, L. C. Fai
Exact analytical solutions to the dissipative time-dependent Schrödinger equation are obtained for a decaying two-state system with decay rates and for levels with…
