Emergent Chern-Simons interactions in 3+1 dimensions
Emergent Chern-Simons interactions in 3+1 dimensions
Parity-violating superconductors can support a low-dimension local interaction that becomes, upon condensation, a purely spatial Chern-Simons term. Solutions to the resulting generalized London equations can be obtained from solutions of the ordinary London equations with a complex penetration depth, and suggest several remarkable physical phenomena. The problem of flux exclusion …
