The discovery of superconductivity in LaFeAsO introduced the ferropnictides as a major new class of superconducting compounds with critical temperatures second only to cuprates. The presence of magnet...
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...
Macroscopic time evolution and MaxEnt inference for closed systems with Hamiltonian dynamics
MaxEnt algorithm information theory statistical mechanics Hamiltonian dynamics
2010/11/24
MaxEnt inference algorithm from the information theory is relevant for the time evolution of macroscopic systems which represents a problem of incomplete information. Two different approaches using Ma...
Can noncommutative effects of quantum nature account for the present speed up of the cosmic expansion?
noncommutative quantum nature account
2010/12/20
In this paper we investigate to which extent noncommutativity, a intrinsically quantum property,may influence the Friedmann-Robertson-Walker cosmological dynamics at late times/large scales.

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...
Topological disentangler for the valence-bond-solid chain
Topological disentangler valence-bond-solid chain
2010/11/23
We discuss topological disentangler for S = 1 quantum spin chains in the Haldane phase. We first point out that Kennedy-Tasaki’s(KT) nonlocal unitary transformation is the perfect disentangler for Aff...
A density-functional approach on the hexagonal graphene lattice is developed using an exact
numerical solution to the Hubbard model as the reference system. Both nearest-neighbour and up
to third ne...
Partitioned quantum cellular automata are intrinsically universal
Partitioned quantum cellular automata intrinsically universal
2010/11/4
There have been several non-axiomatic approaches taken to define Quantum Cellular Automata (QCA). Partitioned QCA (PQCA) are the most canonical of these non-axiomatic definitions. In this work we show...
Optimal Perfect Distinguishability between Unitaries and Quantum Operations
Optimal Perfect Distinguishability Unitaries Quantum Operations
2010/11/4
We study optimal perfect distinguishability between a unitary and a general quantum operation. In 2-dimensional case we provide a simple sufficient and necessary condition for sequential perfect disti...
Affine Maps of the Polarization Vector for Quantum Systems of Arbitrary Dimension
Affine Maps the Polarization Vector Quantum Systems Arbitrary Dimension
2010/11/4
The operator-sum decomposition (OS) of a mapping from one density matrix to another has many applications in quantum information science. To this mapping there corresponds an affine map which provides...
Three-body exclusion principle, duality mapping, and exact ground state of a harmonically trapped, ultracold Bose gas with three-body hard-core interactions in one dimension
duality mapping exact ground state of a harmonically trapped ultracold Bose gas with three-body hard-core interactions
2010/11/19
Motivated by previous suggestions that three-body hard-core interactions in lower-dimensional
ultracold Bose gases might provide a way for creation of non-Abelian anyons, the exact ground
state of a...
Hydrodynamic description of transport in strongly correlated electron systems
Hydrodynamic description strongly correlated electron systems
2010/11/22
We develop a hydrodynamic description of the resistivity and magnetoresistance of an electron
liquid in a smooth disorder potential. This approach is valid when the electron-electron scattering lengt...
We present numerical simulations of a Kerr black hole perturbed by a pulse of ingoing gravitational radiation. For strong perturbations we find up to five concentric marginally outer trapped surfaces....

What is credible and what is incredible in the measurements of the Casimir force
What is credible what is incredible the measurements Casimir force
2010/11/4
We comment on progress in measurements of the Casimir force and discuss what is the actual reliability of different experiments. In this connection a more rigorous approach to the usage of such concep...
