Bright soliton dynamics for seventh degree nonlinear systems with higher-order dispersion
In this study, we investigate the typical systems modeled by the (3 + 1)-dimensional as well as (1 + 1)-dimensional Schrödinger equations incorporating third-order dispersion effects, higher-order scattering effects, and cubic–fifth–seventh degree ...

Advancing Energy Materials by In Situ Atomic Scale Methods
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

A $$\phi ^6$$ ϕ6 soliton with a long-range tail
We propose an analytically solvable sextic potential model with non-trivial soliton solutions connecting the trivial vacua. The model does not respect parity symmetry, and like $$\phi ^4$$ ϕ4 theory has two minima.

Quantum‐Mechanical Wave Functions in Singular Potentials: Linear and Nonlinear States
The attractive singular potential −1/r2$-1/r^2$ gives rise to the quantum collapse in the 3D linear Schroedinger equation. The article summarizes theoretical results demonstrating suppression of the collapse and creation of the missing ground state (GS) in a gas of bosonic particles, carrying an electric dipole moment, which are pulled to the central ...

On-demand tailoring soliton patterns through intracavity spectral phase programming
Multi-pulse oscillations are prevalent phenomena observed in mode-locked lasers and nonlinear microresonators, where the short- and long-range interactions between nonlinear wavepackets give rise to diverse pulse patterns such as soliton molecules ...

Polarization‐Dependence of Nonlinear Optical Effects in Silicon: The Case of Ultrafast Processing
The dependence of the input polarization for the nonlinear optical propagation in silicon is investigated theoretically and experimentally. The perturbative regime is examined using pump‐probe shadowgraphy and nonlinear transmission, whereas the case of permanent laser‐induced modifications is addressed using a combination of Raman micro‐spectroscopy ...

Line Soliton Interactions and Dispersive Magnetoelastic Waves [PDF]
This thesis studies two distinct types of physical wave interactions: line soliton interactions in the Kadomtsev-Petviashvili II (KPII) equation and magnetoelastic interactions in a layered ferromagnetic material.

Multi-soliton dynamics of anti-self-dual gauge fields
We study dynamics of multi-soliton solutions of anti-self-dual Yang-Mills equations for G = GL(2, ℂ) in four-dimensional spaces. The one-soliton solution can be interpreted as a codimension-one soliton in four-dimensional spaces because the principal ...
