Finite-difference time-domain simulation of strong-field ionization: Perfectly matched layer approach
Høgni C. Kamban, Sigurd S. Christensen, Thomas Søndergaard +1
A Finite-Difference Time-Domain (FDTD) scheme with Perfectly Matched Layers (PMLs) is considered for solving the time-dependent Schrödinger equation, and simulate the ionization of…
Quantum spill out in few-nanometer metal gaps: Effect on gap plasmons and reflectance from ultrasharp groove arrays
Enok J. H Skjølstrup, Thomas Søndergaard, Thomas G. Pedersen
Plasmons in ultranarrow metal gaps are highly sensitive to the electron density profile at the metal surfaces. Using a fully quantum mechanical approach, we study the effects of el…
Generalized nonlocal optical response in nanoplasmonics
N. Asger Mortensen, Søren Raza, Martijn Wubs +2
Metallic nanostructures exhibit a multitude of optical resonances associated with localized surface plasmon excitations. Recent observations of plasmonic phenomena at the sub-nanom…
