One-dimensional scattering of fermions in double Dirac delta potentials Santamaría Sanz, Lucía The spectrum of bound and scattering states of the one dimensional Dirac Hamiltonian describing fermions distorted by a static background built from two Dirac delta potentials is studied. A distinction will be made between 'mass-spike' and 'electrostatic' δ-potentials. The second quantisation is then performed to promote the relativistic quantum mechanical problem to a relativistic quantum field theory and study the quantum vacuum interaction energy for fermions confined between opaque plates. The work presented here is a continuation of (Guilarte et al 2019 Front. Phys.7 109). 2025-01-23T08:22:35Z 2025-01-23T08:22:35Z 2025-01-23T08:22:35Z 2023-08 info:eu-repo/semantics/article 1751-8113 http://hdl.handle.net/10259/10006 10.1088/1751-8121/acef0d 1751-8121 eng Journal of Physics A: Mathematical and Theoretical. 2023, V. 56, n. 38, p. 385201 https://doi.org/10.1088/1751-8121/acef0d info:eu-repo/semantics/openAccess IOP Publishing
