Berezinskii-Kosterlitz-Thouless Renormalization Group Flow at a Quantum Phase Transition
Matthias Thamm, Harini Radhakrishnan, Hatem Barghathi +4
We present a controlled numerical study of the Berezinskii-Kosterlitz-Thouless (BKT) transition in the one-dimensional Bose-Hubbard model at unit filling, providing evidence of the…
A Scaling Function for the Particle Entanglement Entropy of Fermions
Harini Radhakrishnan, Matthias Thamm, Hatem Barghathi +2
Entanglement entropy under a particle bipartition provides complementary information to mode entanglement as it is sensitive to interactions and particle statistics at leading orde…
One-particle entanglement for one dimensional spinless fermions after an interaction quantum quench
Matthias Thamm, Harini Radhakrishnan, Hatem Barghathi +2
Particle entanglement provides information on quantum correlations in systems of indistinguishable particles. Here, we study the one particle entanglement entropy for an integrable…
