Abstract

The entanglement entropy for the ground state of an XY spin chain is related to the corner transfer matrices of the triangular Ising lattice and is expressed in closed form.

Entropy of XY Spin Chain and Block Toeplitz Determinants

Alexander Rudol'fovich Its, Bai-Qi 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 block of neighboring spins approaches a constant as the size of the block increases. We prove rigorously expression for limiting entropy which was published before. We observe that the entropy reaches minimum at product states but increases boundlessly at phase transitions.

The Fisher-Hartwig Formula and Generalized Entropies in XY Spin Chain

Alexander Rudol'fovich Its, V. E. Korepin

Toeplitz matrices have applications to different problems of statistical mechanics. Recently they were used for calculation of entanglement entropy in spin chains. We use the Fisher-Hartwig formula to calculate entanglement entropy of large block of spins in the ground state of XY spin chain. We also calculate Renyi entropy and prove that the spectrum of the density matrix of a block of spins is exact geometric sequence [also different eigenvalues are degenerated differently].

Analysis of entropy of XY Spin Chain

Fabio Franchini, Alexander Rudol'fovich Its, Bai-Qi Jin +1 more

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: the size of the block is much larger then 1 but much smaller then the length of the whole chain. In this limit, the entropy of the block approaches a constant. The limiting entropy is a function of the anisotropy and of the magnetic field. The entropy reaches minima at product states and increases boundlessly at phase transitions.

Entanglement entropy of excited states

Vincenzo Alba, Maurizio Fagotti, Pasquale Calabrese

We study the entanglement entropy of a block of contiguous spins in excited states of spin chains. We consider the XY model in a transverse field and the XXZ Heisenberg spin chain. For the latter, we developed a numerical application of the algebraic Bethe ansatz. We find two main classes of states with logarithmic and extensive behavior in the dimension of the block, characterized by the properties of excitations of the state. This behavior can be related to the locality properties of the Hamiltonian having a given state as the ground state. We also provide several details of the finite size scaling.

Exact relationship between the entanglement entropies of XY and quantum Ising chains

Ferenc Iglói, Róbert Juhász

We consider two prototypical quantum models, the spin-1/2 XY chain and the quantum Ising chain and study their entanglement entropy, S (ℓ, L ), of blocks of ℓ spins in homogeneous or inhomogeneous systems of length L . By using two different approaches, free-fermion techniques and perturbational expansion, an exact relationship between the entropies is revealed. Using this relation we translate known results between the two models and obtain, among others, the additive constant of the entropy of the critical homogeneous quantum Ising chain and the effective central charge of the random XY chain.
