Entanglement entropy in quantum spin chains with finite range interaction
A. R. Its, F. Mezzadri, M. Y. Mo
We study the entropy of entanglement of the ground state in a wide family of one-dimensional quantum spin chains whose interaction is of finite range and translation invariant. Suc…
Entanglement in Quantum Spin Chains, Symmetry Classes of Random Matrices, and Conformal Field Theory
J. P. Keating, F. Mezzadri
We compute the entropy of entanglement between the first spins and the rest of the system in the ground states of a general class of quantum spin-chains. We show that under cer…
Random Matrix Theory and Entanglement in Quantum Spin Chains
J. P. Keating, F. Mezzadri
We compute the entropy of entanglement in the ground states of a general class of quantum spin-chain Hamiltonians - those that are related to quadratic forms of Fermi operators - b…
Nodal domain distributions for quantum maps
J. P. Keating, F. Mezzadri, A. G. Monastra
The statistics of the nodal lines and nodal domains of the eigenfunctions of quantum billiards have recently been observed to be fingerprints of the chaoticity of the underlying cl…
