Query: A critical strange metal from fluctuating gauge fields in a solvable
  random model   Building upon techniques employed in the construction of the
Sachdev-Ye-Kitaev (SYK) model, which is a solvable $0+1$ dimensional model of a
non-Fermi liquid, we develop a solvable, infinite-ranged random-hopping model
of fermions coupled to fluctuating U(1) gauge fields. In a specific large-$N$
limit, our model realizes a gapless non-Fermi liquid phase, which combines the
effects of hopping and interaction terms. We derive the thermodynamic
properties of the non-Fermi liquid phase realized by this model, and the charge
transport properties of an infinite-dimensional version with spatial structure.
