Vacuum energy for generalised Dirac combs at $T=0$

Michael Bordag, Jose M Muñoz-Castañeda, Lucía Santamaría-Sanz

The quantum vacuum energy for a hybrid comb of Dirac $\delta$-${\delta }^{\prime }$ potentials is computed using the energy of the single $\delta$-${\delta }^{\prime }$ potential over the real line that makes up the comb. Th…
