Query: Transparent Dirac potentials in one dimension: the time-dependent case   We generalize the original derivation of transparent, static Schroedinger
potentials by Kay and Moses, to obtain a large class of time-dependent
transparent Dirac potentials in one spatial dimension. They contain all known
transparent potentials as special cases and play a key role in the
semi-classical solution of 1+1 dimensional, fermionic quantum field theories of
Gross-Neveu and Nambu-Jona-Lasinio type.
