Entanglement Entropy for Disjoint Subsystems in XX Spin Chain
B. -Q. Jin, V. E. Korepin
Fisher-Hartwig formula has been successful applied to describe the von Neumann and Rényi entropies of a block of spins in the ground state of XX spin chain. It was based on a deter…
Ellipses of Constant Entropy in the XY Spin Chain
F. Franchini, A. R. Its, B. -Q. Jin +1
Entanglement in the ground state of the XY model on the infinite chain can be measured by the von Neumann entropy of a block of neighboring spins. We study a double scaling limit:…
Analysis of entropy of XY Spin Chain
F. Franchini, A. R. Its, B. -Q. Jin +1
Entanglement in the ground state of the XY model on the infinite chain can be measured by the von Neumann entropy of a block of neighboring spins. We study a double scaling limit:…
Entropy of XY Spin Chain and Block Toeplitz Determinants
A. R. Its, B. -Q. Jin, V. E. Korepin
We consider entanglement in the ground state of the XY spin model on infinite chain. We use von Neumann entropy of a sub-system as a measure of entanglement. The entropy of a large…
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…
Correlation Functions in Spin Chains and Information Theory
B. -Q. Jin, V. E. Korepin
Antiferromagnetic spin chains play an important role in condensed matter physics and statistical mechanics. Recently XXX spin chain was discussed in relation to the information the…
