Interactions of Self-Localised Optical Wavepackets in Reorientational Soft Matter
Applied Sciences, 2022 The interaction of optical solitary waves in nematic liquid crystals, nematicons and vortices, with other nematicons and localised structures, such as refractive index changes, is reviewed.

Physical Review D, 2011 We numerically obtain a class of soliton solutions for Einstein gravity in $(n+1)$ dimensions coupled to massive abelian gauge fields and with a negative cosmological constant with Lifshitz asymptotic behaviour. We find that for all $n\geq3$, a discrete set of magic values for the charge density at the origin (guaranteeing an asymptotically Lifshitz ...

A Time Two-Mesh Compact Difference Method for the One-Dimensional Nonlinear Schrödinger Equation
Entropy, 2022 The nonlinear Schrödinger equation is an important model equation in the study of quantum states of physical systems. To improve the computing efficiency, a fast algorithm based on the time two-mesh high-order compact difference scheme for solving the ...

ON NONCOMMUTATIVE SOLITONS [PDF]
Modern Physics Letters A, 2000 We consider (2+1)-dimensional classical noncommutative scalar field theory. The general ansatz for a radially symmetric solution is obtained. Some exact solutions are presented. Their possible physical meaning is discussed. The case of finite θ is discussed qualitatively and illustrated by some numerical results.

Construction of Exact Solutions for Gilson–Pickering Model Using Two Different Approaches
Universe, 2022 In this paper, the extended simple equation method (ESEM) and the generalized Riccati equation mapping (GREM) method are applied to the nonlinear third-order Gilson–Pickering (GP) model to obtain a variety of new exact wave solutions.

Emergence of Solitons from Irregular Waves in Deep Water
Journal of Marine Science and Engineering, 2021 Numerical simulations were performed to study the long-distance evolution of irregular waves in deep water. It was observed that some solitons, which are the theoretical solutions of the nonlinear Schrödinger equation, emerged spontaneously as irregular ...

Research Paper: Soliton Solution of Nonlinear Schrodinger Equation in the Presence of a Minimal Observable Length [PDF]
فیزیک کاربردی ایران, 2021 The unification between the theory of general relativity and the standard model of particle physics predicts the existence of a minimal measurable length on the order of the Planck length. Nowadays phenomenological studies of field theory in the presence

Supersolitons: Solitonic Excitations in Atomic Soliton Chains [PDF]
Physical Review Letters, 2008 We show that, by appropriately tuning physically relevant interactions in two-component nonlinear Schrodinger equations, it is possible to achieve a regime with particle-like solitonic collisions. This allows us to construct an analogue of the Newton's cradle and also to create localized collective excitations in solitary-wave chains which are quasi ...

Propagation and ramification of a solitary pulse through an environmentally coupled qubit
New Journal of Physics, 2020 We compute the relaxations experienced by a superconducting qubit and the simultaneous variation induced on the shape of a microwave pulse during the propagation of the pulse through the qubit.
