Momentum space entanglement of interacting fermions

MO Flynn, LH Tang, A Chandran, CR Laumann - Physical Review B, 2023 - APS
Momentum space entanglement entropy probes quantum correlations in interacting
fermionic phases. It is very sensitive to interactions, obeying volume-law scaling in general …

Superfluid-Insulator Transition unambiguously detected by entanglement in one-dimensional disordered superfluids

GA Canella, VV França - Scientific reports, 2019 - nature.com
We use entanglement to track the superfluid-insulator transition (SIT) in disordered fermionic
superfluids described by the one-dimensional Hubbard model. Entanglement is found to …

Entanglement in disordered superfluids: The impact of density, interaction and harmonic confinement on the Superconductor–Insulator transition

GA Canella, VV França - Physica A: Statistical Mechanics and its …, 2020 - Elsevier
We investigate the influence of density, interaction and harmonic confinement on the
superfluid to insulator transition (SIT) in disordered fermionic superfluids described by the …

Momentum-space entanglement after a quench in one-dimensional disordered fermionic systems

R Lundgren, F Liu, P Laurell, GA Fiete - Physical Review B, 2019 - APS
We numerically investigate the momentum-space entanglement entropy and entanglement
spectrum of the random-dimer model and its generalizations, which circumvent Anderson …

Entanglement contour in the disordered electronic systems

NA Khan, M Jan, G **anlong - Physica E: Low-dimensional Systems and …, 2023 - Elsevier
We investigate the entanglement contour of a one-dimensional non-interacting electronic
systems with two different models of the static disorder. We obtain the scaling behavior of the …
