Maximum Principle vs. Minimum Principle in Non-equilibrium Thermodynamics
Prigogine's Min. principle states that in steady-state non-equilibrium systems the entropy generation rate is at a minimum, i.e., a system will seek a steady-state that has min entropy generation. ...

Phase volume contraction in dissipative systems
I am confused about phase-volume contraction in dissipative systems. Please help me catch the flaw in my understanding. From a macroscopic point of view I understand that a dynamic system tends to go ...

What is non-thermal plasma?
I read about non-thermal plasma, but I still have some questions:
The ions and neutral particles are not in thermal equilibrium with the electron, does that mean that the overall temperature is low ...

Does high entropy means low symmetry?
According to Bogolubov postulate (various texts name it differently) in Non-equilibrium thermodynamics, the number of needed parameters to describe our system is decreasing with time, and finally at ...

State-dependent diffusions: Fick's law vs. Fokker-Planck's, which and why?
Consider a "state-dependent diffusion": a diffusion process for which the diffusion coefficient $D(x)$ depends on the (stochastic) state $x$ of the system. (An example is provided by the diffusion of ...

Can the work done between two non-equilibrium states be calculated?
The work done during a process between two equilibrium states can be described by thermodynamics. Even when process itself is out of equilibrium, the thermodynamic laws can still be used, though ...
