Limiting free energy per particle for Ising Model by approximating its functional integral
Rong Qiang Wei
There have been a lot of methods aimed at studying the limiting free energy per particle (LFEPP) for 3-dimensional (3D) Ising model in absence of an external magnetic field. These…
Simple series solutions to specific heat-phonon spectrum inversion
Rong Qiang Wei
The specific heat-phonon spectrum inversion has played a significant role in solid physics. But for this inherently ill-posed problem, most of the known solutions are complex both…
An empirical partition function for the simple cubic Ising Model with a zero external magnetic field
Rong Qiang Wei
There is no an accepted exact partition function (PF) for the three dimensional (3D) Ising model to our knowledge. Mainly based on the connection between the lattice Green function…
An empirical partition function for two-dimensional Ising Model in an external magnetic field
Rong Qiang Wei
There is no an accepted exact partition function (PF) for the two-dimensional (2D) Ising model with a non-zero external magnetic field to our knowledge. Here we infer an empirical…
