d-wave Superfluid with Gapless Edges in a Cold Atom Trap

Anne-Louise Gadsbolle, H. Francis Song, Karyn Le Hur

We consider a strongly repulsive fermionic gas in a two-dimensional optical lattice confined by a harmonic trapping potential. To address the strongly repulsive regime, we consider…

Detecting Quantum Critical Points using Bipartite Fluctuations

Stephan Rachel, Nicolas Laflorencie, H. Francis Song +1

We show that the concept of bipartite fluctuations F provides a very efficient tool to detect quantum phase transitions in strongly correlated systems. Using state of the art numer…

Bipartite Fluctuations as a Probe of Many-Body Entanglement

H. Francis Song, Stephan Rachel, Christian Flindt +3

We investigate in detail the behavior of the bipartite fluctuations of particle number and spin in many-body quantum systems, focusing on systems where such U…

Entanglement Entropy of the Two-Dimensional Heisenberg Antiferromagnet

H. Francis Song, Nicolas Laflorencie, Stephan Rachel +1

We compute the von Neumann and generalized Rényi entanglement entropies in the ground-state of the spin-1/2 antiferromagnetic Heisenberg model on the square lattice using the modif…

Entanglement from Charge Statistics: Exact Relations for Many-Body Systems

H. Francis Song, Christian Flindt, Stephan Rachel +2

We present exact formulas for the entanglement and Rényi entropies generated at a quantum point contact (QPC) in terms of the statistics of charge fluctuations, which we illustrate…

General Relation between Entanglement and Fluctuations in One Dimension

H. Francis Song, Stephan Rachel, Karyn Le Hur

In one dimension very general results from conformal field theory and exact calculations for certain quantum spin systems have established universal scaling properties of the entan…
