00925njm 22002777a 4500 dc Bordag, Michael author Muñoz Castañeda, José María author Santamaría Sanz, Lucía author 2019-04 The quantum vacuum energy for a hybrid comb of Dirac δ-δ′ potentials is computed by using the energy of the single δ-δ′ potential over the real line that makes up the comb. The zeta function of a comb periodic potential is the continuous sum of zeta functions over the dual primitive cell of Bloch quasi-momenta. The result obtained for the quantum vacuum energy is non-perturbative in the sense that the energy function is not analytical for small couplings. http://hdl.handle.net/10259/10323 10.3389/fphy.2019.00038 2296-424X Quantum vacuum Casimir effect (theory) Condensed matter Quantum field theories (QFT) Selfadjoint extensions Vacuum Energy for Generalized Dirac Combs at T = 0
