Title: Topological order in quantum matter
Abstract: Ideas on topological order have played a prominent role in studies of states of quantum matter with an energy gap: e.g. spin liquid insulators and fractional quantum Hall liquids. However these ideas can also be important in gapless states, including in metals found in numerous correlated electron compounds. I will present simple models of metals with topological order, and compare some results with numerical studies of the Hubbard model on the square lattice.

Quantum Café is CCQ’s ongoing seminar series: open to all bona fide members of the greater NYC scientific community and held every second week, Quantum Café presents a series of informal, highly interactive talks, typically by external speakers, which present the most interesting recent developments and open questions in our field.
