DESCRIPTION:Given a many-body system in (2+1) dimensions with a conserved 
 U(1) current\, an interesting probe of the IR dynamics is provided by weak
 ly gauging the current and then studying the correlation functions of magn
 etic monopole operators in the resulting dynamical gauge theory. This corr
 elation function is a non-perturbative object and so is somewhat difficult
  to calculate using conventional techniques. We review the expected behavi
 or of such monopole correlations in different field-theoretical states. We
  then turn to holography and study monopole correlations in holographic li
 quids with fundamental flavor\, where the monopole operator is dual to a b
 ulk particle that carries magnetic charge\, permitting a simple geometric 
 understanding. We display consistency with expected field-theoretical resu
 lts. For a charge-gapped phase this requires a discussion of monopole cond
 ensation in the bulk\, which turns out to be equivalent to the capping off
  of the bulk flavor brane. In a compressible finite-density phase we prese
 nt a novel calculation of the monopole correlation in space and time.
