Constrained Random Phase Approximation: the spectral method
Merzuk Kaltak, Alexander Hampel, Martin Schlipf +3
We present a constrained Random Phase Approximation (cRPA) method, termed spectral cRPA (s-cRPA), and compare it to established cRPA approaches for Scandium and Copper by varying t…
Comparative analysis of methods for calculating Hubbard parameters using cRPA
Indukuru Ramesh Reddy, M. Kaltak, Bongjae Kim
In this study, we present a systematic comparison of various approaches within the constrained random-phase approximation (cRPA) for calculating the Coulomb interaction parameter $…
Efficient periodic density functional theory calculations of charged molecules and surfaces using Coulomb kernel truncation
Sudarshan Vijay, Martin Schlipf, Henrique Miranda +4
Density functional theory (DFT) calculations of charged molecules and surfaces are critical to applications in electro-catalysis, energy materials and related fields of materials s…
Density-Based Long-Range Electrostatic Descriptors for Machine Learning Force Fields
Carolin Faller, Merzuk Kaltak, Georg Kresse
This study presents a long-range descriptor for machine learning force fields (MLFFs) that maintains translational and rotational symmetry, similar to short-range descriptors while…
