Enhanced compressibility due to repulsive interaction in the Harper model
Yaacov E. Kraus, Oded Zilberberg, Richard Berkovits
We study the interplay between repulsive interaction and an almost staggered on-site potential in one-dimension. Specifically, we address the Harper model for spinless fermions wit…

Entanglement entropy of low-lying excitation in localized interacting system: Signature of Fock space delocalization
Richard Berkovits
The properties of the entanglement entropy (EE) of low-lying excitations in one-dimensional disordered interacting systems are studied. The ground state EE shows a clear signature…

Two particle excited states entanglement entropy in a one-dimensional ring
Richard Berkovits
The properties of the entanglement entropy (EE) of two particle excited states in a one-dimensional ring are studied. For a clean system we show analytically that as long as the mo…
