Quantum Crystals, Quantum Computing and Quantum Cognition
Speaker(s): Matthew Fisher
Abstract: Quantum mechanics is down to earth - quite literally - since the electrons within the tiny crystals found in a handful of dirt manifest a dizzying world of quantum motion. Each crystal has it’s own unique choreography, with the electrons entangled in a myriad of quantum dances. Quantum entanglemen... read more

Can Eigenstate Thermalization Breakdown without Disorder?
Speaker(s): Matthew Fisher
Abstract: We describe a new diagnostic for many-body wavefunctions which generalizes the spatial bipartite entanglement entropy. By was of illustration, for a two-component wavefunction of heavy and light particles, a partial (projective) measurement of the coordinates of the heavy (but not light) particles i... read more

Quantum Tapestries
Speaker(s): Matthew Fisher
Abstract: Within each of nature's crystals is an exotic quantum world of electrons weaving to and fro. Each crystal has it's own unique tapestry, as varied as the crystals themselves. In some crystals, the electrons weave an orderly quilt. Within others, the electrons are seemingly entwined in an entangled we... read more

A 3d Boson Topological Insulator and the “Statistical Witten Effect”
Speaker(s): Matthew Fisher
Abstract: Electron topological insulators are members of a broad class of “symmetry protected topological” (SPT) phases of fermions and bosons which possess distinctive surface behavior protected by bulk symmetries. For 1d and 2d SPT’s the surfaces are either gapless or symmetry broken, while in 3d, gap... read more

Gapless Spin Liquids in Two Dimensions
Speaker(s): Matthew Fisher
Abstract: Many crystalline materials predicted by band theory to be metals are insulators due to strong electron interactions. Both experiment and theory suggest that such Mott-insulators can exhibit exotic gapless spin-liquid ground states, having no magnetic or any other order. Such “critical spin... read more
