Inhomogeneous field theory inside the arctic circle
Nicolas Allegra, Jérôme Dubail, Jean-Marie Stéphan +1
Motivated by quantum quenches in spin chains, a one-dimensional toy-model of fermionic particles evolving in imaginary-time from a domain-wall initial state is solved. The main int…
Unusual Corrections to Scaling and Convergence of Universal Renyi Properties at Quantum Critical Points
Sharmistha Sahoo, E. Miles Stoudenmire, Jean-Marie Stéphan +3
At a quantum critical point, bipartite entanglement entropies have universal quantities which are subleading to the ubiquitous area law. For Renyi entropies, these terms are known…
Inhomogeneous quenches in a fermionic chain: exact results
Jacopo Viti, Jean-Marie Stéphan, Jérôme Dubail +1
We consider the non-equilibrium physics induced by joining together two tight binding fermionic chains to form a single chain. Before being joined, each chain is in a many-fermion…
