Topological Mott Insulators and Discontinuous -Terms
Michael A. DeMarco, Ethan Lake, Xiao-Gang Wen
We introduce a lattice field theory that describes the transition between a superfluid (SF) and a bosonic topological Mott Insulator (tMI) -- a symmetry protected topologica…
RG and Stability in the Exciton Bose Liquid
Ethan Lake
The exciton Bose liquid (EBL) is a hypothesized phase of bosons in 2+1D which possesses a dispersion that is gapless along the coordinate axes in momentum space. The low energy the…
Spontaneous breaking of multipole symmetries
Charles Stahl, Ethan Lake, Rahul Nandkishore
Multipole symmetries are of interest both as a window on fracton physics and as a crucial ingredient in realizing new universality classes for quantum dynamics. Here we address the…
Subdimensional criticality: condensation of lineons and planons in the X-cube model
Ethan Lake, Michael Hermele
We study quantum phase transitions out of the fracton ordered phase of the X-cube model. These phase transitions occur when various types of sub-dimensional excitati…
Re-entrant Superconductivity Through a Quantum Lifshitz Transition in Twisted Trilayer Graphene
Ethan Lake, T. Senthil
A series of recent experiments have demonstrated robust superconductivity in magic-angle twisted trilayer graphene (TTG). In particular, a recent work by Cao et al. (arxiv:2103.120…
Bose-Luttinger Liquids
Ethan Lake, T. Senthil, Ashvin Vishwanath
We study systems of bosons whose low-energy excitations are located along a spherical submanifold of momentum space. We argue for the existence of gapless phases which we dub "Bose…
