Emergence of graviton-like excitations from a lattice model

December 4, 2019 @ 4:30 pm - 5:30 pm

Speaker: Xiao-Gang Wen (MIT)
Title: Emergence of gravitonlike excitations from a lattice model
Abstract: I will review some construction of lattice rotor model which give rise to emergent photons and gravitonlike excitations. The appearance of vector-like charge and symmetric tensor field may be related to gapless fracton phases.
