First-Principles Theory of Spatial Dispersion: Dynamical Quadrupoles and Flexoelectricity
Density-functional perturbation theory (DFPT) is nowadays the method of choice for the accurate computation of linear and nonlinear-response properties of materials from first principles. A notable advantage of DFPT over alternative approaches is the possibility of treating incommensurate lattice di...
