Bordag, Michael Muñoz Castañeda, José María Santamaría Sanz, Lucía 2025-03-13T10:27:50Z 2025-03-13T10:27:50Z 2019-04 http://hdl.handle.net/10259/10323 10.3389/fphy.2019.00038 2296-424X 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. eng http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Atribución 4.0 Internacional Quantum vacuum Casimir effect (theory) Condensed matter Quantum field theories (QFT) Selfadjoint extensions Vacuum Energy for Generalized Dirac Combs at T = 0 info:eu-repo/semantics/article
