Casimir Effect for Massless Fermions in One Dimension: A Force-Operator Approach
We calculate the Casimir interaction between two short-range scatterers embedded in a background of onedimensional massless Dirac fermions using a force-operator approach. We obtain the force between two finitewidth square barriers and take the limit of zero width and infinite potential strength to study the Casimir force mediated by the fermions. For the case of identical scatterers, we recove...
متن کاملThe Casimir Effect for Fermions in One Dimension
We study the Casimir problem for a fermion coupled to a static background field in one space dimension. We examine the relationship between interactions and boundary conditions for the Dirac field. In the limit that the background becomes concentrated at a point (a “Dirac spike”) and couples strongly, it implements a confining boundary condition. We compute the Casimir energy for a masslike bac...

متن کاملCasimir forces in a T-operator approach
We explore the scattering approach to Casimir forces. Our main tool is the description of Casimir energy in terms of transition operators. The approach is valid for scalar fields as well as for electromagnetic fields. We provide several equivalent derivations of the formula presented by Kenneth and Klich Phys. Rev. Lett. 97, 160401 2006 . We study the convergence properties of the formula and h...
متن کاملTopological phases of fermions in one dimension
In this paper we show how the classification of topological phases in insulators and superconductors is changed by interactions, in the case of one-dimensional systems. We focus on the time-reversal-invariant Majorana chain (BDI symmetry class). While the band classification yields an integer topological index k, it is known that phases characterized by values of k in the same equivalence class...
