Query: Thermometry of ultracold fermions by (super)lattice modulation
  spectroscopy   We theoretically consider non-interacting fermions confined to optical
lattices and apply a lattice amplitude modulation that we choose to be either
homogeneous or of superlattice geometry. We study the atom excitation rate to
higher Bloch bands which can be measured by adiabatic band mapping. We find
that the atom excitation rate shows a clear signature of the temperature
dependent Fermi distribution in the lowest band of the equilibrium lattice as
excitations are quasimomentum-resolved. Based on typical experimental
parameters and incorporating a trapping potential, we find that thermometry of
one- and two-dimensional systems is within the reach of nowadays experiments.
Our scheme is valid down to temperatures of a few percent of the hopping
amplitude comparable to the N\'eel temperature in interacting systems.
