Dynamics of Hermite–Gaussian beams in the linear and nonlocal nonlinear fractional Schrödinger equations

open access: yesResults in Physics, 2020
We analytically and numerically investigated the dynamics of the Hermite–Gaussian (HG) beams in linear and nonlocal nonlinear fractional Schrödinger equations (SEs), in both one and two dimensions.

Two-Dimensional Spectroscopy of Two-Dimensional Materials

open access: yes, 2022
In this work we provide an exact and efficient numerical approach to simulate multi-time correlation functions in the Mahan-Nozières-De Dominicis model, which crudely mimics the spectral properties of doped two-dimensional semiconductors such as monolayer transition metal dichalcogenides.

Kinematics of interacting solitons in two-dimensional space [PDF]

open access: yes, 2020
A simple kinematic approach to the description of the interaction between solitons is developed. It is applicable to both integrable and non-integrable two-dimensional models, including those commonly used for studying the surface and internal oceanic ...
