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…

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…
