Add to Calendar 10/24/2018 4:00 pm 10/24/2018 America/Chicago Physics Colloquium: "Classical simulations of quantum liquids: entanglement as barrier and opportunity" DESCRIPTION:

Entanglement provides fantastic richness to quantum many-body systems, but also leads to exponential barriers in our ability to numerically simulate them with classical computers. Fortunately,  in the ground state entanglement takes a special form, and understanding its structure has proven key to developing efficient new numerical methods. Quantum information measures can further be used to numerically demonstrate the existence of fractionalized quasiparticles and emergent gauge fields in models where they  might otherwise evade detection. I will discuss how combining these techniques has provided evidence for the  emergence of quantum electrodynamics and deconfined gauge fields in “realistic” models like the triangular and kagome lattice Hubbard models.
