Screening in the finite-temperature reduced Hartree-Fock model
Antoine Levitt
We prove the existence of solutions of the reduced Hartree-Fock equations at finite temperature for a periodic crystal with a small defect, and show total screening of the defect c…

Numerical quadrature in the Brillouin zone for periodic Schrodinger operators
Eric Cances, Virginie Ehrlacher, David Gontier +2
As a consequence of Bloch's theorem, the numerical computation of the fermionic ground state density matrices and energies of periodic Schrodinger operators involves integrals over…

Variational formulation for Wannier functions with entangled band structure
Anil Damle, Antoine Levitt, Lin Lin
Wannier functions provide a localized representation of spectral subspaces of periodic Hamiltonians, and play an important role for interpreting and accelerating Hartree-Fock and K…
