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…
Overlap distributions for quantum quenches in the anisotropic Heisenberg chain
Paolo P. Mazza, Jean-Marie Stéphan, Elena Canovi +3
The dynamics after a quantum quench is determined by the weights of the initial state in the eigenspectrum of the final Hamiltonian, i.e., by the distribution of overlaps in the en…
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…
A Rényi entropy perspective on topological order in classical toric code models
Johannes Helmes, Jean-Marie Stéphan, Simon Trebst
Concepts of information theory are increasingly used to characterize collective phenomena in condensed matter systems, such as the use of entanglement entropies to identify emergen…
