Assessing the effect of polariton interactions on the formation of polariton condensates in 2D Molybdenum Diselenide (MoSe2)

Two Dimensional (2D) transition metal dichalcogenide (TMD) materials are defined by the emergence of new properties resulting from collective quantum effects and by holding promise for their quantum applications. Recently, through adiabatic impulse approximation (AIA) and the Brundobler-Elser (BE) conjecture, we investigated coherent control of polaritonic entities in 2D TMD materials of 2H types [Physica Scripta 97(2), 025801 (2022)] , which induces several applications. We realized that, among 2D TMD materials of 2H types, 2D Molybdenum Diselenide (MoSe 2 ) is the best candidate to form polariton condensates. In the present research work, we reported the influence of polariton-polariton interactions on the formation of polariton condensates in 2D TMD MoSe 2 embedded in 2D microcavity. Under rotating wave and adiabatic impulse approximations, we investigated both Landau Energy Levels (LELs) and Landau-Zener (LZ) diabatic and adiabatic transition probabilities of the system of laser cooled and trapped polariton in 2D TMD MoSe 2 embedded in 2D microcavity. Numerical results reveal that polariton-polariton interactions reduce the total energy of the system and governs the transition probability of finding the cooled and trapped polariton in the ground state. Thus, by providing a means to manipulate the dynamics of polaritons under intense laser radiation, polariton-polariton interactions are detrimental to the formation of polariton condensates. We formally recommended the utilization of laser cooled and trapped polaritons in 2D TMD MoSe 2 embedded in 2D microcavity with intense laser radiation and under the influence of low polariton-polariton interactions for successful implementation of quantum devices.
