Spintronics and quantum information science are two promising candidates for innovating
information processing technologies. The combination of these two fields enables us to build …

All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

We carry out a systematic study of entanglement entropy in relativistic quantum field theory.
This is defined as the von Neumann entropy SA=− Tr ρ A logρ A corresponding to the …

Recent interest in aspects common to quantum information and condensed matter has
prompted a flurry of activity at the border of these disciplines that were far distant until a few …

Physical interactions in quantum many-body systems are typically local: Individual
constituents interact mainly with their few nearest neighbors. This locality of interactions is …

Entanglement, one of the most intriguing features of quantum theory and a main resource in
quantum information science, is expected to play a crucial role also in the study of quantum …

One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

We review recent developments in the physics of ultracold atomic and molecular gases in
optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard …

A phase transition describes the sudden change of state of a physical system, such as
melting or freezing. Quantum gases provide the opportunity to establish a direct link …

This review focuses on the field of quantum entanglement applied to condensed matter
physics systems with strong correlations, a domain which has rapidly grown over the last …
