Quantum spin chains and random matrix theory
Huw J Wells
The spectral statistics and entanglement within the eigenstates of generic spin chain Hamiltonians are analysed. A class of random matrix ensembles is defined which include the mos…

Spectra and eigenstates of spin chain Hamiltonians
J. P. Keating, N. Linden, H. J. Wells
We prove that translationally invariant Hamiltonians of a chain of qubits with nearest-neighbour interactions have two seemingly contradictory features. Firstly in the limit $n…

Random matrices and quantum spin chains
J. P. Keating, N. Linden, H. J. Wells
Random matrix ensembles are introduced that respect the local tensor structure of Hamiltonians describing a chain of distinguishable spin-half particles with nearest-neighbour…
