Extended Lagrangian Born-Oppenheimer Molecular Dynamics with DFT+U
Yu Zhang, Marc J. Cawkwell, Christian F. A. Negre +2
Extended Lagrangian Born-Oppenheimer molecular dynamics (XL-BOMD) [Phys. Rev. Lett. vol. 100, 123004 (2008)] is combined with Kohn-Sham density functional theory (DFT) using a DFT+…
Spin-Polarized Extended Lagrangian Born-Oppenheimer Molecular Dynamics
Yu Zhang, Marc J. Cawkwell, Christian F. A. Negre +2
We present a generalization of Extended Lagrangian Born-Oppenheimer molecular dynamics [Phys. Rev. Lett. vol. 100, 123004 (2008); Eur. Phys. J. B vol. 94, 164 (2021)] that also inc…
Canonical density matrix perturbation theory
Anders M. N. Niklasson, Marc J. Cawkwell, Emanuel H. Rubensson +1
Density matrix perturbation theory [Niklasson and Challacombe, Phys. Rev. Lett. 92, 193001 (2004)] is generalized to canonical (NVT) free energy ensembles in tight-binding, Hartree…
Generalized Extended Lagrangian Born-Oppenheimer Molecular Dynamics
Anders M. N. Niklasson, Marc J. Cawkwell
Extended Lagrangian Born-Oppenheimer molecular dynamics based on Kohn-Sham density functional theory is generalized in the limit of vanishing self-consistent field optimization pri…
