First-principles electron-phonon scattering in real-time TDDFT
Zhengwei Nie, Subhojit Pal, Marti Lüders +4
Real-time time-dependent density functional theory provides a first-principles description of coherent electron dynamics in laser-driven solids, but its unitary formulation cannot…
Attractive and repulsive terms in multi-filament dispersion interactions
Subhojit Pal, John F. Dobson, Mathias Boström
Filamentary objects such as nano-wires, nanotubes and DNA are of current interest in physics, nanoscience, chemistry, biology and medicine. They can interact via strong, exceptiona…
Inverse design for Casimir-Lifshitz force near heterogeneous gapped metal surface
M. Boström, S. Pal, H. R. Gopidi +4
The Casimir-Lifshitz force is calculated between a heterogeneous gapped metal surface and a silica sphere attached to an AFM cantilever tip. We demonstrate that heterogeneous surfa…
Do 1-dimensional metals prefer to form even-numbered van der Waals clusters ?
Subhojit Pal, John F. Dobson
Parallel quasi-one-dimensional metals are known to experience strong dispersion (van der Waals, vdW) interactions that fall off unusually slowly with separation between the metals.…
