Spin-projection orientations in the plane square-lattice Ising model with periodic boundary conditions
You-gang Feng
The periodic boundary conditions changed the plane square-lattice Ising model to the torus-lattice system which restricts the spin-projection orientations. Only two of the three im…

Microscopic origin of the second law of thermodynamics
You-gang Feng
We proved when random-variable fluctuations obey the central limit theorem the equality of the uncertainty relation corresponds to the thermodynamic equilibrium state. The inequali…

Uncertainty relation and quantitative condition of inversion symmetry of time in many-particle system
You-gang Feng
We proved that the uncertainty relation fits in with many-particle system and the equality of the relation corresponds to the thermodynamic equilibrium state, the inequality of the…
