Bisognano-Wichmann Hamiltonian for the entanglement spectroscopy of fractional quantum Hall states
A. Nardin, R. Lopes, M. Rizzi +2
We study the Bisognano-Wichmann Hamiltonian for fractional quantum Hall states defined on a sphere and explore its relationship with the entanglement Hamiltonian associated to the…
