On the invariant quantities in an entropy balance and their impact on the stability of some physical systems
Andrea Di Vita
In a wide class of physical systems, diffeomorphisms in the state space leave the amount of entropy produced per unit time inside the bulk of the system unaffected [M. Polettini et…

On a non-linear sigma model of knotted relaxed states far from thermodynamic equilibrium in plasma physics and beyond
Andrea Di Vita
We show that a Faddeev-Niemi non-linear sigma model describes in the long wavelength limit a wide class of steady-state, knotted physical systems far from thermodynamic equilibrium…

On a necessary criterion for stability of steady solutions of complex Ginzburg-Landau equation -- a counterexample to the 'maximum entropy production principle'
Andrea Di Vita
A maximum entropy production principle (MEPP) has been postulated to be a criterion of stability for steady states of open systems [Martyushev et al., Phys. Rep. 426, 1 (2006)]. We…
