Selective Vibronic Excitation for Coherent Energy Transport in Photosynthetic and Agrivoltaic Systems
Steve Cabrel Teguia Kouam, Theodore Goumai Vedekoi, Jean-Pierre Tchapet Njafa +2
Partitioning the photonic environment into resonant and off-resonant modes provides a mechanism for dephasing suppression in photosynthetic energy transfer. Aligning the excitation…
Optomechanical entanglement induced by backward stimulated Brillouin scattering
P. Djorwé, A. H. Abdel-Aty, K. S. Nisar +1
We propose a scheme to generate robust optomechanical entanglement. This scheme is based on a Backward Stimulated Brillouin Scattering (BSBS) process, which is hosted within an opt…
Quantum entanglement assisted via Duffing nonlinearity
D. R. Kenigoule Massembele, P. Djorwé, Amarendra K. Sarma +2
We propose a scheme to enhance quantum entanglement in an optomechanical system by exploiting the so-called Duffing nonlinearity. Our model system consists of two mechanically coup…
symmetry and chaos control via dissipative optomechanical coupling
S. R. Mbokop Tchounda, P. Djorwé, M. V. Tchakui +1
We study a dissipative, mechanically coupled optomechanical system that accommodates gain and loss. The gain (loss) is engineered by driven a purely dispersive optomechanical cavit…
Synthetic magnetism for solitons in optomechanical array
P. Djorwé, H. Alphonse, S. Abbagari +2
We propose a synthetic magnetism to generate and to control solitonic waves in optomechanical array. Each optomechanical cavity in the array couples to its neighbors thro…
Sensor sensitivity based on synthetic magnetism exceptional point
S. R. Mbokop Tchounda, P. Djorwé, S. G. Nana Engo +1
An efficient mass sensor based on exceptional points (EPs), engineered under synthetic magnetism requirement, is proposed. The benchmark system consists of an electromechanical (op…
Robustness of continuous-variable entanglement via geometrical nonlinearity
Philippe Djorwé, S. G. Nana Engo, Paul Woafo
We propose a scheme to generate robust stationary continuous-variable entanglement in optomechanical systems, based on geometrical nonlinearity that occurs for large mechanical dis…
Quantum associative memory for the diagnosis of some tropical diseases
J. -P. Tchapet Njafa, S. G. Nana Engo, P. Woafo
In this paper we present a model of Quantum Associative Memory which can be a helpful tool for physicians without experience or laboratory facilities, for the diagnosis of four tro…
Limiting effects of geometrical and optical nonlinearities on the squeezing in optomechanics
P. Djorwé, S. G. Nana Engo, J. H. Talla Mbé +1
In recent experiments, the re-thermalization time of the mechanical resonator is stated as the limiting factor for quantum applications of optomechanical systems. To explain the or…
Concise Quantum Associative Memories with Nonlinear Search Algorithm
J. -P. Tchapet Njafa, S. G. Nana Engo
The model of quantum associative memories (QAM) we propose here consists in simplifying and generalizing that of Rigui Zhou \etal \cite{zhou2012} who uses the quantum matrix with b…
Quantum associative memory with improved distributed queries
J. -P. Tchapet Njafa, S. G. Nana Engo, Paul Woafo
The paper proposes an improved quantum associative algorithm with distributed query based on model proposed by Ezhov et al. We introduce two modifications of the query that optimiz…
