Microscopic Realization of 2-Dimensional Bosonic Topological
... ask why time reversal symmetry is not broken by condensing b02 = b2 S − . At first glance, it seems that T is broken since hb02 i is not invariant under T . However, since b02 carries charge of the gauge field a2 , it is not gauge invariant. In other words, the Lagrangian (3) is invariant under the ...

The fields ‘a’ and/or ‘b’ can be spin-1/2, spin-0 or spin-1. • The original derivation (done by both Bethe & Salpeter and Schwinger as well) was done in 1951 for spin-1/2 particles which turns out to be the s ...
