Entanglement in XY Spin Chain
A. R. Its, B. -Q. Jin, V. E. Korepin
We consider the ground state of the XY model on an infinite chain at zero temperature. Following Bennett, Bernstein, Popescu, and Schumacher we use entropy of a sub-system as a mea…
Quantum Communication Through a Spin-Ring with Twisted Boundary Conditions
S. Bose, B. -Q. Jin, V. E. Korepin
We investigate quantum communication between the sites of a spin-ring with twisted boundary conditions. Such boundary conditions can be achieved by a flux through the ring. We find…
Entanglement in a Valence-Bond-Solid State
Heng Fan, Vladimir Korepin, Vwani Roychowdhury
We study entanglement in Valence-Bond-Solid state. It describes the ground state of Affleck, Kennedy, Lieb and Tasaki quantum spin chain. The AKLT model has a gap and open boundary…
Universality of the one dimensional Bose gas with delta interaction
Luigi Amico, Vladimir Korepin
We consider several models of interacting bosons in a one dimensional lattice. Some of them are not integrable like the Bose-Hubbard others are integrable. At low density all of th…
