Nonlinear Diamagnetic Interactions in Ultrastrongly Coupled 2D Electrons
Dasom Kim, Kiran M. Kulkarni, Vaibhav Sharma +15
The quantum Hopfield model is widely used to describe ultrastrong light--matter coupling between cavity photons and collective bosonic excitations in solids, where the diamagnetic…
Electron- and Lattice-Temperature Dependence of the Optical Response of Gold Nanoparticles
Nour E. H. Chetoui, Jonas Grumm, Robert Lemke +2
Transient absorption spectroscopy is routinely used to study the electron dynamics in plasmonic gold nanoparticles. Typically, the transient absorption bleach is analyzed as measur…
Boltzmann-Bloch Equation Approach to the Theory of the Optical Inter- and Intraband Response in Noble Metals
Robert Lemke, Matthias Rössle, Holger Lange +2
In this paper we introduce momentum-resolved metal Boltzmann-Bloch equations (MBBE) for the combined description of electronic intra- and interband processes in noble metals. This…
Ultrafast Electrons in Noble Metals: Orientational Relaxation, Thermalization and Cooling in Terms of Electron-Phonon Interaction
Jonas Grumm, Andreas Knorr
We investigate the momentum-resolved dynamics of conduction electrons in noble metals following ultrashort optical excitation with linearly polarized light. Using a momentum-resolv…
Theory of Non-Linear Electron Relaxation in Thin Gold Films and Their Signatures in Optical Observables
Jonas Grumm, Malte Selig, Holger Lange +1
Based on the momentum-resolved Boltzmann equation, we provide self-consistent numerical calculations of the dynamics of conduction electrons in thin noble metal films after linear…
