标题： Formation of Solitonic Bound State via Light-Matter Interaction

摘要： 通过光-物质相互作用进行能量交换为各种非线性动力系统提供了新的维度。 在这里，研究了当两个反向传播的、正交极化的激光脉冲入射到原子凝聚体时，光-物质相互作用的影响。 观察到，局域的激光脉冲轮廓可以在玻色-爱因斯坦凝聚体中诱导出局域模式。 使用类似Vakhitov-Kolokolov的标准进行的稳定性分析表明，当原子-原子相互作用为排斥性时，这些局域模式是稳定的。 通过原子色散，在稳定区域内研究了光-物质相互作用和原子-原子相互作用对Lieb模的影响，当光学势为Pöschl-Teller型时，揭示了束缚态形成的特征。 能级图还表明，当光-物质相互作用改变符号时，能量会从激光脉冲连续转移到原子上。 显示英文摘要

摘要： Exchange of energy by means of light-matter interaction provides a new dimension to various nonlinear dynamical systems. Here, the effects of light-matter interaction are investigated for a situation, where two counter-propagating, orthogonally polarized laser pulses are incident on the atomic condensate. It's observed that a localized laser pulse profile can induce localized modes in Bose-Einstein condensate. A stability analysis performed using Vakhitov-Kolokolov-like criterion has established that these localized modes are stable, when the atom-atom interaction is repulsive. The cooperative effects of light-matter interactions and atom-atom interactions on the Lieb-mode have been studied in the stable region through atomic dispersion, revealing the signature of bound state formation when the optical potential is P\"oschl-Teller type. The energy diagram also indicates a continuous transfer of energy from the laser pulses to the atoms as the light-matter interaction changes its sign.
