Query: Bose-Einstein condensation vs. localization of bosonic quasiparticles in
  disordered weakly-coupled dimer antiferromagnets   We investigate the field-induced insulator-to-superfluid transition of
bosonic quasiparticles in $S=1/2$ weakly-coupled dimer antiferromagnets. In
presence of realistic disorder due to site dilution of the magnetic lattice, we
show that the system displays an extended Bose-glass phase characterized by the
localization of the hard-core quasiparticles.
