The paper explores in detail the intricate relationship between the results of the quantum-chemical calculations and the approximations they rely upon. When chemists want (or need) to include some ...
INTRODUCTION: Density functional theory (DFT) is a widely used method for calculating the electronic properties of materials. The method is based on the idea of approximating the many-electron wave ...
Ultracold atomic gases have several advantages over materials for systematically exploring fermionic quantum systems. In materials, strong interactions go hand in hand with increasing localization of ...
