Anomaly in the relaxation dynamics close to the surface plasmon resonance
Guillaume Weick, Dietmar Weinmann, Gert-Ludwig Ingold +1
We propose an explanation for the anomalous behaviour observed in the relaxation dynamics of the differential optical transmission of noble-metal nanoparticles. Using the temperatu…
Relation between phase space coverage and entanglement for spin-1/2 systems
Stefan Schenk, Gert-Ludwig Ingold
For systems of two and three spins 1/2 it is known that the second moment of the Husimi function can be related to entanglement properties of the corresponding states. Here, we gen…
Lissajous curves and semiclassical theory: The two-dimensional harmonic oscillator
Roland Doll, Gert-Ludwig Ingold
The semiclassical treatment of the two-dimensional harmonic oscillator provides an instructive example of the relation between classical motion and the quantum mechanical energy sp…
Surface plasmon in metallic nanoparticles: renormalization effects due to electron-hole excitations
Guillaume Weick, Gert-Ludwig Ingold, Rodolfo A. Jalabert +1
The electronic environment causes decoherence and dissipation of the collective surface plasmon excitation in metallic nanoparticles. We show that the coupling to the electronic en…
Quantum Brownian motion and the Third Law of thermodynamics
Peter Hänggi, Gert-Ludwig Ingold
The quantum thermodynamic behavior of small systems is investigated in presence of finite quantum dissipation. We consider the archetype cases of a damped harmonic oscillator and a…
