Stable high-order solitons in spiral potentials
Liangwei Dong, Jingyi Deng, Changming Huang +1
We present a comprehensive study of optical solitons supported by spiral potentials in media with the cubic-quintic (CQ) nonlinearity. A variety of families of stationary states, i…
Collisions and fusion of one- and two-dimensional solitons driven by potential troughs in the cubic-quintic nonlinear Schrödinger equations
Liangwei Zeng, Boris A. Malomed, Dumitru Mihalache +2
We study the formation and collision of one- and two-dimensional (1D and 2D) Gaussian-shaped and flat-top (FT) solitons in the framework of the nonlinear Schrödinger equation with…
Quasi-confined modes produced by the Lugiato-Lefever model with a localized pump and the pseudo-Raman term
Evgeny M. Gromov, Boris A. Malomed
We introduce an extended nonlinear Lugiato-Lefever equation (LLE) with the pseudo-stimulated-Raman-scattering (pseudo-SRS) cubic term, linear damping/gain, and spatial inhomogeneou…
Multi-pole solitons and breathers with spatially periodic modulation induced by the helicoidal spin-orbit coupling
Cui-Cui Ding, Qin Zhou, B. A. Malomed
We report analytical solutions for diverse multi-pole (MP) soliton and breather states in spatially inhomogeneous binary Bose-Einstein condensates (BECs) with the helicoidally shap…
Multidimensional Soliton Systems: an Update
Boris A. Malomed
A briefly formulated update of the recently published review [1] on the topic of multidimensional solitons (chiefly, in nonlinear optics and atomic Bose-Einstein condensates (BECs)…
Stability of the Quantum Coherent Superradiant States in Relation to Exciton-Phonon Interactions and the Fundamental Soliton in Hybrid Perovskites
A. A. Gladkij, N. A. Veretenov, N. N. Rosanov +3
The use of macroscopic coherent quantum states at room temperature is crucial in modern quantum technologies. In light of recent experiments demonstrating high-temperature superflu…
