Santamaría Sanz, Lucía 2025-01-22T17:00:36Z 2025-01-22T17:00:36Z 2024-04 http://hdl.handle.net/10259/10000 10.1093/ptep/ptae059 2050-3911 The quantum vacuum interaction energy between a pair of semitransparent two-dimensional plates represented by Dirac delta potentials and its first derivative, embedded in the topological background of a sine-Gordon kink, is studied through an extension of the TGTG-formula (developped by O. Kenneth and I. Klich in the scattering approach). Quantum vacuum oscillations around the sine-Gordon kink solutions are interpreted as a quantum scalar field theory in the spacetime of a domain wall. Moreover, the relation between the phase shift and the density of states (the well-known Dashen–Hasslacher–Neveu or DHN formula) is also exploited to characterize the quantum vacuum energy. application/pdf eng Oxford University Press Progress of Theoretical and Experimental Physics. 2024, V. 2024, n. 5 https://doi.org/10.1093/ptep/ptae059 Atribución 4.0 Internacional http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Física Physics Casimir Energy through Transfer Operators for Sine-Gordon Backgrounds info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Progress of Theoretical and Experimental Physics 2024 5
