Entanglement entropy of ground states of the three-dimensional ideal Fermi gas in a magnetic field
Paul Pfeiffer, Wolfgang Spitzer
We study the asymptotic growth of the entanglement entropy of ground states of non-interacting (spinless) fermions in subject to a non-zero, constant magnetic field p…

On the stability of the area law for the entanglement entropy of the Landau Hamiltonian
Paul Pfeiffer
We consider the two-dimensional ideal Fermi gas subject to a magnetic field which is perpendicular to the Euclidean plane and whose strength at $x\in\mathbb R^…
