Decay of Interatomic Force Constants in the Reduced Hartree-Fock Model
Eric Cances, Antoine Levitt, Jack Thomas
We study the decay of the interatomic force constants (equivalently, the smoothness properties of the dynamical matrix) in perfect crystals both at finite electronic temperature, a…

New perspectives on Density-Matrix Embedding Theory
Alicia Negre, Fabian Faulstich, Raehyun Kim +3
Quantum embedding methods enable the study of large, strongly correlated quantum systems by (usually self-consistent) decomposition into computationally manageable subproblems, in…
