Pranay Gorantla: (Princeton): Exotic QFTs: Lifshitz Theory, Tensor Gauge Theory, and Fractons (Zoom)
Date: 2022-04-25
Abstract: I will discuss some exotic QFTs which exhibit several peculiar features such as strange ground state degeneracy (GSD), defects with restricted mobility (a.k.a. fractons), and UV/IR mixing. I will focus on simple examples in 1+1d with dipole symmetries, including the compact Lifshitz field theory, and the symmetric rank-2 tensor gauge theory. Interestingly, in all our examples, there are several different continuum theories described by the same Lagrangian. I will also explain how the strange GSD and restricted mobility arise as consequences of space-like and time- like dipole global symmetries. Based on work with Ho Tat Lam, Nathan Seiberg, and
Shu-Heng Shao (arXiv:2201.10589).
