Anderson's orthogonality catastrophe in one dimension induced by a magnetic field
Hans Konrad Knörr, Peter Otte, Wolfgang Spitzer
According to Anderson's orthogonality catastrophe, the overlap of the -particle ground states of a free Fermi gas with and without an (electric) potential decays in the thermody…
