The realization of Bose Einstein condensates (BEC) and quantum degenerate Fermi gases
with cold atoms has been a highlight of quantum physics during the past decade. Cold …

The physics of one-dimensional interacting bosonic systems is reviewed. Beginning with
results from exactly solvable models and computational approaches, the concept of bosonic …

We propose an ordered set of experimentally accessible conditions for detecting
entanglement in mixed states. The k-th condition involves comparing moments of the …

Quantum computers, though not yet available on the market, will revolutionize the future of
information processing. Quantum computers for special purposes like quantum simulators …

These notes are the write-up and extension of the lectures I gave over a few years for a class
on “Introduction to Bethe Ansatz” within the Ph. D. program in Statistical Physics at SISSA …

This book presents in a pedagogical yet complete way correlated systems in one dimension.
Recent progress in nanotechnology and material research have made one dimensional …

The transverse field Ising and XY models (the simplest quantum spin models) provide the
organising principle for the rich variety of interconnected subjects which are covered in this …

Quantum Dissipative Systems : Introduction Page 1 1 Introduction Quantum-statistical
mechanics is a very rich and checkered field. It is the theory dealing with the dynamical …

Similarly to the system Hamiltonian, a subsystem's reduced density matrix is composed of
blocks characterized by symmetry quantum numbers (charge sectors). We present a …

Presenting the physics of the most challenging problems in condensed matter using the
conceptual framework of quantum field theory, this book is of great interest to physicists in …
