Observation of multi-skyrmion objects created by size and density control in Ta/CoFeB/MgO films
Christian Denker, Sören Nielsen, Enno Lage +7
Magnetic skyrmions are chiral spin textures with a nontrivial topology that offer a potential for future magnetic memory and storage devices. The controlled formation and adjustmen…
Exploring non-adiabatic approximations to the exchange-correlation functional of TDDFT
Johanna I. Fuks, Lionel Lacombe, Soeren E. B. Nielsen +1
A decomposition of the exact exchange-correlation potential of time-dependent density functional theory into an interaction component and a kinetic component offers a new starting…
Time-Dependent Density Functional Theory Beyond Kohn-Sham Slater Determinants
Johanna I. Fuks, Soeren E. B. Nielsen, Michael Ruggenthaler +1
When running time-dependent density functional theory (TDDFT) calculations for real-time simulations of non-equilibrium dynamics, the user has a choice of initial Kohn-Sham state,…
Exact Density-Functionals with Initial-State Dependence and Memory
M. Ruggenthaler, S. E. B. Nielsen, R. van Leeuwen
We analytically construct the wave function that, for a given initial state, produces a prescribed density for a quantum ring with two non-interacting particles in a singlet state.…
