Halevi's extension of the Euler-Drude model for plasmonic systems
Gino Wegner, Dan-Nha Huynh, N. Asger Mortensen +2
The nonlocal response of plasmonic materials and nanostructures is usually described within a hydrodynamic approach which is based on the Euler-Drude equation. In this work, we rec…
Time-domain modeling of interband transitions in plasmonic systems
Max Pfeifer, Dan-Nha Huynh, Gino Wegner +3
Efficient modeling of dispersive materials via time-domain simulations of the Maxwell equations relies on the technique of auxiliary differential equations. In this approach, a mat…
The missing link between standing- and traveling-wave resonators
Qi Zhong, Haoqi Zhao, Liang Feng +3
Optical resonators are structures that utilize wave interference and feedback to confine light in all three dimensions. Depending on the feedback mechanism, resonators can support…
Two-Particle Tight-Binding Description of Higher-Harmonic Generation in Semiconductor Nanostructures
Ulf Peschel, Thomas Lettau, Stefanie Gräfe +1
We develop a quantum mechanical theory to describe the optical response of semiconductor nanostructures with a particular emphasis on higher-order harmonic Generation. Based on a t…
The importance of substrates for the visibility of "dark" plasmonic modes
Saskia Fiedler, Søren Raza, Ruoqi Ai +5
Dark plasmonic modes have interesting properties, such as a longer lifetime and a narrower linewidth than their radiative counterpart, as well as little to no radiative losses. How…
Modeling electromagnetic resonators using quasinormal modes
Philip Trøst Kristensen, Kathrin Herrmann, Francesco Intravaia +1
We present a bi-orthogonal approach for modeling the response of localized electromagnetic resonators using quasinormal modes, which represent the natural, dissipative eigenmodes o…
