Abstract

Tunnel current-voltage characteristics are calculated for symmetric junctions between metals waves of with charge or spin density that have equal absolute values |Σ| of the dielectric order parameter. The possibility of different signs for Σ on opposite sides of the junction is considered. As a result, the current-voltage characteristics are highly asymmetric. The predicted effect is a new example of symmetry breaking in many particle systems and makes it possible to explain some experimental data for symmetric URu2Si2-URu2Si2 microjunctions.
