First order phase transition in the few-body XY-models with surface fields
Xintian Wu
We investigate the one-dimensional finite-size XY model with opposing surface fields in the X direction. Exact solutions are obtained for the two-site and three-site models, while…
Quasi time crystal
Xintian Wu
We discuss the possibility of making a quasi time crystal. A simple two-state model is studied to clarify our definition. In a superposition of the ground state and the excited sta…
Wetting transition in the McCoy-Wu model
Xintian Wu
The wetting transition is studied in the McCoy-Wu Ising model in which the random bonds are perfectly correlated in the direction parallel to the walls . The model is solved numeri…
The Landau-Ginzburg-Wilson Hamiltonian for the Griffiths phase
Xintian Wu
The Landau-Ginzburg-Wilson Hamiltonian with random temperature for the phase transition in disordered systems from the Griffiths phase to ferromagnetic phase is reexamined. From th…
The critical phenomena of a single defect
Xintian Wu, Yangyang Zhang
We consider the critical system with a point defect and study the variation of thermodynamic quantities, which are the differences between those with and without the defect. Within…
The critical 2-dimensional Ising model with fixed boundaries
Xintian Wu, Nickolay Izmailyan
The critical 2-dimensional Ising model is studied with four types boundary conditions: free, fixed ferromagnetic, fixed antiferromagnetic, fixed double antiferromagnetic. Using Bon…
