User-defined Electrostatic Potentials in DFT Supercell Calculations: Implementation and Application to Electrified Interfaces
Samuel Mattoso, Jing Yang, Florian Deißenbeck +5
Introducing electric fields into density functional theory (DFT) calculations is essential for understanding electrochemical processes, interfacial phenomena, and the behavior of m…
Dielectric properties of nanoconfined water from ab initio thermopotentiostat molecular dynamics
F. Deißenbeck, S. Wippermann
We discuss how to include our recently proposed thermopotentiostat technique [Phys. Rev. Lett. 126, 136803 (2021)] into any existing ab initio molecular dynamics (AIMD) package. Us…
Dielectric properties of nano-confined water: a canonical thermopotentiostat approach
F. Deißenbeck, C. Freysoldt, M. Todorova +2
We introduce a novel approach to sample the canonical ensemble at constant temperature and applied electric potential. Our approach can be straightforwardly implemented into any de…
Ground state of dipolar hard spheres confined in channels
Florian Deißenbeck, Hartmut Löwen, Erdal C. Oğuz
We investigate the ground state of a classical two-dimensional system of hard-sphere dipoles confined between two hard walls. Using lattice sum minimization techniques we reveal th…
