Orbital angular momentum induced bistability in a quantum system

Abstract

In this article, we have proposed a unique approach to adjust optical bistability (OB) and optical multistability (OM) in a ring cavity inclusive of a three-level quantum system primarily based on quantum mean-field theory. The quantum system interacts with a weak probe light, an incoherent pumping field and a robust coupling light which carries an optical vortex that is an electromagnetic light with optical angular momentum. We confirmed that the real and imaginary parts of the susceptibility of the no-vortex probe light relies on the azimuthal angle and orbital angular momentum (OAM) of the vortex light whilst the quantum interference time period will become important. Moreover, we determined that because of the OAM number of vortex light, the switching from OB to OM is feasible for extraordinary azimuthal angle. These functions of such a three-level quantum system are not stated in any comparable studies.

“…A pivotal requirement is the interaction between a light source and a material, which can span across diverse mediums [13][14][15][16][17][18][19]. When an atom engages with a field, the resulting atomic coherence emerges as a crucial mechanism, facilitating effective control and modulation of the optical properties within quantum systems [20][21][22][23][24][25].…”

“…primarily based on quantum interference phenomena and atomic coherence [5][6][7]. The foundations of quantum coherence and interference extend to atom-field interactions [8][9][10][11], measurement theory [12], enormous Kerr nonlinearities [13], and many other areas of atomic physics and quantum optics [14][15][16][17]. For quantum interference-based 1D atom grating, several different techniques have been presented [18][19][20][21].…”

“…EIT has found extensive use in the study of light-matter interactions, owing to its noteworthy quantum coherent properties [2][3][4][5][6][7]. EIT is particularly relevant for diverse applications, including slow light [8][9][10], the creation of a significant nonlinear response [11,12], the generation of an electromagnetically induced grating (EIG) [13][14][15][16][17][18] and other related phenomena [5,[19][20][21][22][23][24][25]. Recent studies have observed the EIG phenomenon in atomic systems, quantum wells, and quantum dots [26][27][28].…”
