Phase transition and critical properties of spin-orbital interacting systems
Huai-Bao Tang, Dong-Meng Chen, Xiang-Fei Wei +1
Phase transition and critical properties of Ising-like spin-orbital interacting systems in 2-dimensional triangular lattice are investigated. We first show that the ground state of…

Exact solutions of semilinear radial wave equations in n dimensions
Stephen C. Anco, Sheng Liu
Exact solutions are derived for an n-dimensional radial wave equation with a general power nonlinearity. The method, which is applicable more generally to other nonlinear PDEs, inv…
