Interaction corrections to topological density three-point functions in two-dimensional Fermi liquids: a coadjoint orbit perspective
Akshay Pal, Andrew Lucas, Umang Mehta
Density three-point correlations are known to probe the topology of the Fermi sea in two-dimensional noninteracting systems. Here, we study how these correlations are modified by i…
Coloring in anyon superconductivity
Umang Mehta, Yuto Nakajima, Hart Goldman
The recently observed signatures of superconductivity proximate to a fractional quantum anomalous Hall (FQAH) state in a twisted MoTe bilayer has revitalized interest in quantu…
Thermodynamics of dilute anyon gases from fusion constraints
Yuto Nakajima, Umang Mehta, Hart Goldman
Recent measurements on 2d materials tuning between fractional quantum anomalous Hall phases and a plethora of correlated electronic states call for a detailed understanding of the…
Symmetry and causality constraints on Fermi liquids
Luca V. Delacrétaz, Subham Dutta Chowdhury, Umang Mehta
We investigate symmetry and causality constraints on interacting Fermi liquids. Whereas Galilean or Lorentz boost symmetry leads to a well-known constraint on the first Landau para…
