Query: Topological Defect Density in One-Dimensional Friedmann-Robertson-Walker
  Cosmological Model: Corrections Inferred from the
  Multi-Josephson-Junction-Loop Experiment   The data on a strongly-nonequilibrium superconducting phase transition in the
multi-Josephson-junction loop (MJJL), which represents a close analog of
one-dimensional Friedmann-Robertson-Walker cosmological model, are used to
refine a concentration of topological defects after the phase transitions of
Higgs fields in the early Universe. The thermal correlations between the phases
of order parameter revealed in MJJL can reduce considerably the expected number
of cosmological defects and, thereby, show a new way to resolve the
long-standing problem of their excessive concentration.
