Quantum Phase Transitions
TL;DR: In this paper, the role of pertubative renormalization group (RG) approaches and self-consistent renormalized spin fluctuation (SCR-SF) theories to understand the quantum-classical crossover in the vicinity of the quantum critical point with generalization to the Kondo effect in heavy-fermion systems is discussed.

Entanglement entropy of random quantum critical points in one dimension
Gil Refael,Joel E. Moore +1 more
TL;DR: It is shown that for a class of strongly random quantum spin chains, the same logarithmic scaling holds for mean entanglement at criticality and defines a critical entropy equivalent to central charge in the pure case.
Journal ArticleDOI
Cosmology and Particle Astrophysics
TL;DR: The role of neutrinos in the role of Neutrinos is discussed in this paper, where the cosmological models of the early universe are discussed as well as special and general Relativity.
Journal ArticleDOI
Non-locality Correlation in Two Driven Qubits Inside an Open Coherent Cavity: Trace Norm Distance and Maximum Bell Function.
TL;DR: It is shown that, the generated non-locality correlations crucially depend on the decay and the initial coherence intensity of the cavity field, and the phenomena of sudden birth and death entanglement are found.

When Is a Non-Markovian Quantum Process Classical?
Simon Milz,Simon Milz,Dario Egloff,Dario Egloff,Philip Taranto,Thomas Theurer,Martin B. Plenio,Andrea Smirne,Andrea Smirne,Andrea Smirne,Susana F. Huelga +10 more
TL;DR: A new paradigm for separating what is inherently quantum from what is classical relies solely on observable quantities and makes it possible to identify the mechanisms leading to nonclassicality in a wide range of situations as discussed by the authors.

Teleporting an unknown quantum state via dual classical and Einstein-Podolsky-Rosen channels

Absence of Diffusion in Certain Random Lattices
TL;DR: In this article, a simple model for spin diffusion or conduction in the "impurity band" is presented, which involves transport in a lattice which is in some sense random, and in them diffusion is expected to take place via quantum jumps between localized sites.
