  We study the structure of Bogoliubov quasiparticles, 'bogolons,' the
fermionic excitations of paired superfluids that arise from fermion (BCS)
pairing, including neutral superfluids, superconductors, and paired quantum
Hall states. The naive construction of a stationary quasiparticle in which the
deformation of the pair field is neglected leads to a contradiction: it carries
a net electrical current even though it does not move. However, treating the
pair field self-consistently resolves this problem: In a neutral superfluid, a
dipolar current pattern is associated with the quasiparticle for which the
total current vanishes. When Maxwell electrodynamics is included, as
appropriate to a superconductor, this pattern is confined over a penetration
depth. For paired quantum Hall states of composite fermions, the Maxwell term
is replaced by a Chern-Simons term, which leads to a dipolar charge
distribution and consequently to a dipolar current pattern.
