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....
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...

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 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

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.
Non-equilibrium dynamics of bosonic atoms in optical lattices: Decoherence of many-body states due to spontaneous emission
Non-equilibrium dynamics of bosonic atoms optical lattices Decoherence of many-body states spontaneous emission
2010/10/21
We analyze in detail the heating of bosonic atoms in an optical lattice due to incoherent scattering of light from the lasers forming the lattice. Because atoms scattered into higher bands do not ther...
Dynamical evolution of quantum oscillators towards equilibrium
Dynamical evolution quantum oscillators equilibrium
2010/4/8
A pure quantum state of large number N of oscillators, interacting via harmonic coupling, evolves such that any small subsystem n<equilibrium. This provides a novel e...
Charge and spin transport in strongly correlated one-dimensional quantum systems driven far from equilibrium
Charge and spin transport one-dimensional quantum systems driven equilibrium
2010/4/13
We study the charge conductivity in one-dimensional prototype models of interacting particles, such as the Hubbard and the t-V spinless fermion model, when coupled to some external baths injecting and...
A framework for the investigation of disordered quantum systems in thermal equilibrium is proposed. The approach is based on a dynamical model--which consists of a combination of a double-bracket grad...
