Rényi entanglement entropies in quantum dimer models : from criticality to topological order
Jean-Marie Stéphan, Grégoire Misguich, Vincent Pasquier
Thanks to Pfaffian techniques, we study the Rényi entanglement entropies and the entanglement spectrum of large subsystems for two-dimensional Rokhsar-Kivelson wave functions const…
Local quantum quenches in critical one-dimensional systems: entanglement, the Loschmidt echo, and light-cone effects
Jean-Marie Stéphan, Jérôme Dubail
We study a particular type of local quench in a generic quantum critical one-dimensional system, using conformal field theory (CFT) techniques, and providing numerical checks of th…
Phase transition in the Rényi-Shannon entropy of Luttinger liquids
Jean-Marie Stéphan, Grégoire Misguich, Vincent Pasquier
The Rényi-Shannon entropy associated to critical quantum spins chain with central charge is shown to have a phase transition at some value of the Rényi parameter wh…
