During the present century a considerable literature has grown up reporting the association of trauma or illness of the central nervous system with the appearance of an illness closely resembling schizophrenia. However, these reports have been scattered and the possibility that organic trauma of the brain could cause schizophrenia in the absence of a heredity or premorbid personality indicative...

The representation of ground states fermionic quantum impurity problems as superpositions Gaussian has recently been given a rigorous mathematical foundation [S. Bravyi and D. Gosset, Commun. Math. Phys. 356, 451 (2017)]. It is natural to ask how many parameters are required for an efficient variational scheme based on this representation. An upper bound $O({N}^{2})$, where $N$ the system size,...

The mean field limit for systems of many fermions is naturally coupled with a semiclassical limit. This makes the analysis of the mean field regime much more involved, compared with bosonic systems. In this paper, we study the dynamics of initial data close to a Slater determinant, whose reduced one-particle density is an orthogonal projection ωN with the appropriate semiclassical structure. As...

The n-electron ground state of the Friedel resonance model can be written as a single Slater determinant of n s-electrons plus one d-electron-s-hole companion. This new formula is derived geometrically in the Hilbert space. The derivation uses the fact that a n-electron Slater determinant, built from N band states, corresponds to a n-dimensional subspace in the N-dimensional Hilbert space. PACS...
