Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Investigating the Origin of Topological‐Hall‐Like Resistivity in Zn‐Doped Mn2Sb Ferrimagnet

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Skyrmions and other chiral spin textures have been extensively studied as potential building blocks for novel spintronic devices. Hall‐resistivity anomalies that deviate from magnetization scaling, known as the topological Hall effect, have been widely employed as evidence for the presence of chiral spin textures in magnetic materials. However,

N-Soliton Solutions of the Nonisospectral Generalized Sawada-Kotera Equation

Advances in Mathematical Physics, 2014
The soliton interaction is investigated based on solving the nonisospectral generalized Sawada-Kotera (GSK) equation. By using Hirota method, the analytic one-, two-, three-, and N-soliton solutions of this model are obtained.

Insights from the nonlinear Schrödinger–Hirota equation with chromatic dispersion: Dynamics in fiber–optic communication

Nonlinear Engineering
Optical solitons have practical applications in communication systems as carriers of optical information. An advantage of an optical soliton is its ability to maintain its structure unchanged when interacting with other pulses.
