Entanglement and classical correlations at the doping-driven Mott transition in the two-dimensional Hubbard model
C. Walsh, P. Sémon, D. Poulin +2
Tools of quantum information theory offer a new perspective to characterize phases and phase transitions in interacting many-body quantum systems. The Hubbard model is the archetyp…
Thermodynamic and information-theoretic description of the Mott transition in the two-dimensional Hubbard model
C. Walsh, P. Sémon, D. Poulin +2
At the Mott transition, electron-electron interaction changes a metal, in which electrons are itinerant, to an insulator, in which electrons are localized. This phenomenon is centr…
Entanglement entropy and mutual information across the Mott transition in the two-dimensional Hubbard model
C. Walsh, P. Sémon, D. Poulin +2
Entanglement and information are powerful lenses to probe phases transitions in many-body systems. Motivated by recent cold atom experiments, which are now able to measure the corr…
Detecting Topological Order with Ribbon Operators
Jacob C. Bridgeman, Steven T. Flammia, David Poulin
We introduce a numerical method for identifying topological order in two-dimensional models based on one-dimensional bulk operators. The idea is to identify approximate symmetries…
