Quantum Thermalization and Novel Phases in Non-equilibrium Quantum Systems
Quantum Thermalization Non-equilibrium Quantum Systems Novel Phases
2023/1/4
Universal quantum computers offer us the opportunities to implement novel quantum matter far away from equilibrium states. There has been remarkable progress in our understanding of the non-ergodic an...
Quantum Ground States as Equilibrium Particle-Vacuum Interaction States
Quantum ground states Vacuum fluctuations Particle‐vacuum interaction states Zero‐point fluctuations Harmonic oscillator quantum ground state
2012/4/20
A remarkable feature of atomic ground states is that they are observed to be radiationless in nature, despite (from a classical viewpoint) typically involving charged particles in accelerated motions....
Newtonian limit and trend to equilibrium for the relativistic Fokker-Planck equation
Relativistic Fokker-Planck equation Newtonian limit Trend to equilibrium
2011/9/21
Abstract: The relativistic Fokker-Planck equation, in which the speed of light $c$ appears as a parameter, is considered. It is shown that in the limit $c\to\infty$ its solutions converge in $L^1$ to ...

Non-equilibrium Steady States Quantum Systems Star Graphs
2011/7/27
Abstract: Non-equilibrium steady states of quantum fields on star graphs are explicitly constructed. These states are parametrized by the temperature and the chemical potential, associated with each e...
Trends to equilibrium for a class of relativistic diffusions
Relativisic diffusions Relativistic Ornstein-Uhlenbeck process Equilibrium measure
2011/7/28
Abstract: We address the question of the trends to equilibrium for a large class C of relativistic diffusions. We show the existence of a spectral gap using the Lyapounov method and deduce the exponen...
Exponential return to equilibrium for hypoelliptic quadratic systems
Quadratic operators hypoellipticity return to equilibrium rate of convergence
2011/7/26
Abstract: We study the problem of convergence to equilibrium for evolution equations associated to general quadratic operators. Quadratic operators are non-selfadjoint differential operators with comp...
Equilibrium Distributions and Superconductivity
generalized functions equilibrium distribution superconductivity
2011/7/26
Abstract: In this article two models for charges distributions are discussed. On the basis of our consideration we put different points of view for stationary state. We prove that only finite energy m...
Aggregation of superparamagnetic colloids in magnetic fields: the quest for the equilibrium state
Aggregation of superparamagnetic magnetic
2010/11/25
Experimental and simulation studies of superparamagnetic colloids in strong external fields have systematically shown an irreversible aggregation process in which chains of particles steadily grow and...
A Note on Non-equilibrium Work Fluctuations and Equilibrium Free Energies
Classical Statistical Mechanics Thermodynamics Non-equilibrium and Irreversible Thermodynamics
2010/11/24
We consider in this paper, a few important issues in non-equilibrium work fluctuations and
their relations to equilibrium free energies. First we show that Jarzynski identity can be viewed as a cumul...
Bipartite Entanglement in Out-of-equilibrium Correlated Many-body Systems
Bipartite Entanglement Out-of-equilibrium Correlated Many-body Systems
2010/11/19
Relaxation and thermalization after e.g a quantum quench play a central role in out-of-equilibrium physics (e.g. of ultracold atoms) and electronic transport phenomena. On the other hand, entanglement...

2010/11/24
A non-equilibrium extension of Onsager’s canonical theory of thermal fluctuations is employed
to derive a self-consistent theory for the description of the statistical properties of the instantaneous...

Non-equilibrium physics holographic chiral phase transition
2011/1/7
The D3/D7 system holographically describes an N=2 gauge theory which in the presence of a magnetic field. At finite temperature it displays a first order phase transiion.We study out of equilibrium dy...

2010/11/22
A modified version of the Hamiltonian Mean Field model is considered, by including the effect
of an externally imposed magnetic field. This latter is shown to significantly alter the system
behaviou...
Non-equilibrium steady states : maximization of the Shannon entropy associated to the distribution of dynamical trajectories in the presence of constraints
Non-equilibrium steady states Shannon entropy distribution of dynamical trajectories
2010/11/18
Filyokov and Karpov [Inzhenerno-Fizicheskii Zhurnal 13, 624 (1967)] have proposed a theory of
non-equilibrium steady states in direct analogy with the theory of equilibrium states : the principle is ...
Non-equilibrium fluctuations at the QCD phase transition
Non-equilibrium fluctuations QCD phase transition
2011/1/7
We study the chiral phase transition by the non-equilibrium propagation of the sigma field. A quark fluid acts as a heat bath in local thermal equilibrium and evolves fluid dynamically.
