Nonrelativistic Conformal Collider Physics of Multiparticle Point Production
Cyuan-Han Chang, Subham Dutta Chowdhury, Ian Moult +1
We define detector operators in the nonrelativistic conformal field theory describing fermions at unitarity. We reduce the problem of computing the momentum distribution and correl…
Bootstrapping transport in the Drude-Kadanoff-Martin model
Subham Dutta Chowdhury, Sean A. Hartnoll, Aditya Hebbar +1
The Drude-Kadanoff-Martin model is a simple low energy and long wavelength description of charge transport, parameterised by the current relaxation timescale , charge diffusivi…
Lieb-Robinson causality and non-Fermi liquids
Subham Dutta Chowdhury, Sean A. Hartnoll, Aditya Hebbar
Quantum mechanical lattice models with local, bounded interactions obey Lieb-Robinson causality. We show that this implies a domain of analyticity of the retarded Green's function…
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…
