Explaining the cuspy dark matter halo by Landau-Ginzburg theory
Dong-Biao Kang
Twenty three years ago, cosmological N-body simulations revealed quasi-universal NFW dark matter halos, whose physical origin is still unclear. This work tries to solve this issue…
An interpretation of the acceleration of the universe's expansion
Dong-Biao Kang
We have observed the acceleration of the expansion of the universe. To explain this phenomenon, we usually introduce the dark energy (DE) which has a negative pressure or we need t…
Different thermodynamics of self-gravitating systems and discussions for some observations and simulations
Dong-Biao Kang
Our previous works have shown the statistical mechanics of self-gravitating system. In this paper, we will show its thermodynamics and compare our results with observations and sim…
Fluid-like entropy and equilibrium statistical mechanics of self-gravitating systems
Dong-Biao Kang, Ping He
The statistical mechanics of self-gravitating systems has not been well understood, and still remains an open question so far. In a previous study by Kang & He, we showed that the…
Saddle-point entropy states of equilibrated self-gravitating systems
Ping He, Dong-Biao Kang
In this Letter, we investigate the stability of the statistical equilibrium of spherically symmetric collisionless self-gravitating systems. By calculating the second variation of…
A statistical-mechanical explanation of dark matter halo properties
Dong-Biao Kang, Ping He
Cosmological N-body simulations have revealed many empirical relationships of dark matter halos, yet the physical origin of these halo properties still remains unclear. On the othe…
