IQIM Postdoctoral and Graduate Student Seminar

Abstract: In recent years, a theoretical new class of three-dimensional gapped phases of quantum matter has risen to the fore. These phases, originally discovered in the search for a self-correcting quantum memory, are said to exhibit fractonic order --- a novel form of long-range entanglement similar to intrinsic topological order, but distinct from it due to a striking dependence of the universal properties of a phase on lattice geometry. This dependence manifests in a number of exotic features including fractional excitations with constrained mobility, unusually slow thermalization dynamics, and ground state degeneracy that grows with system size. In this talk, I will give an introduction to the topic, and describe recent progress towards a systematic understanding of these phases in terms of emergent gauge theory and entanglement renormalization group flow.
