Augmented Orbital Minimization Method for Linear Scaling Electronic Structure Calculations
Eiji Tsuchida · Journal of the Physical Society of Japan · 2007
We present a novel algorithm which can overcome the drawbacks of the conventional linear scaling method with minimal computational overhead. This is achieved by introducing additional constraints, thus eliminating the redundancy of the orbitals. The performance of our algorithm is evaluated in ab initio molecular-dynamics simulations as well as in a model system.
