Exact Nonlinear Waves and Spin Textures in a Pauli-Type Spin-Orbit-Coupled Gross–Pitaevskii System

Longitudinal Spin Response and Amplitude Fluctuations in the Triangular-Lattice Hubbard Antiferromagnet

Orbital Hall conductivity in a d-wave altermagnet: a multi-orbital tight-binding study

Altermagnets combine zero net magnetization with momentum-dependent spin splitting, and their hallmark transport phenomenon—the spin-splitter effect—requires no spin–orbit coupling (SOC). Here we ask how the orbital degree of freedom fits into this picture. Using a minimal multi-orbital (\documentclass[12pt]{minimal} \...

Spherically symmetric vacuum solution in Freund–Nambu scalar–tensor gravity

We present an exact solution in Freund–Nambu scalar–tensor gravity that extends the Janis–Newman–Winnicour (JNW) naked-singularity spacetime. The metric retains the JNW form governed by parameter n, while a new parameter q deforms the profile of the massive scalar field φ.\documentclass[12pt]{minimal} \usepackage{amsma...
