Universal entanglement spectra in critical spin chains
Rex Lundgren, Jonathan Blair, Pontus Laurell +4
We advocate that in critical spin chains, and possibly in a larger class of 1D critical models, a gap in the momentum-space entanglement spectrum separates the universal part of th…

Momentum-Space Entanglement Spectrum of Bosons and Fermions with Interactions
Rex Lundgren, Jonathan Blair, Martin Greiter +3
We study the momentum space entanglement spectra of bosonic and fermionic formulations of the spin-1/2 XXZ chain with analytical methods and exact diagonalization. We investigate t…
