Quantum Dirac fermions in a half-space and their interaction with an electromagnetic field
We study the polarization tensor of a Dirac field in (3 þ 1) dimensions confined to a half-space-a problem motivated by applications to the condensed matter physics, and to topological insulators in particular. Although the Pauli-Villars regularization scheme has a number of advantages, like explici...
