Author(s): Matthew A. Stoodley, Luke A. Rochford, Tien-Lin Lee, Benedikt P. Klein, David A. Duncan, and Reinhard J. MaurerWe report the quantitative adsorption structure of pristine graphene on Cu(111) determined using the normal incidence x-ray standing wave technique. The experiments constitute an important benchmark reference for the development...

Author(s): Samarth Agrawal, Sandra Galmarini, and Martin KrögerInvestigating heterogeneous materials’ microstructure, often simulated using periodic images, is crucial for understanding their physical traits. We propose a generic spring-based representation for periodic two-component structures. The equilibrium energy in this framework serves as an...

Author(s): Sergey Prosandeev, Charles Paillard, and L. BellaicheWe derive a numerical method based on coupled density functional theory and effective Hamiltonian schemes to calculate the linear and quadratic electro-optic response of ferroelectrics at finite temperature and in different frequency ranges. By applying the developed method to BaTiO3, we...

BasovPump-probe nano-optical experiments were used to study the light-induced insulator to metal transition (IMT) in thin films of vanadium dioxide (VO2), a prototypical correlated electron system. We show that inhomogeneous...
