Quantum Listenings -- Amateur Sonification of Vacuum and other Noises
Carsten Henkel
The sensory perceptions of vision and sound may be considered as complementary doorways towards interpreting and understanding physical phenomena. We provide a few selected samples…
Quantum Borderlines -- Fluctuation Energies in Ultracold Bose Gases
Carsten Henkel
Ultracold Bose gases are many-body systems with well-defined particle interactions that may serve as models for interacting quantum fields. The impact of virtual excitations is stu…
Reflection phase shifts of bouncing Bogoliubov waves
Carsten Henkel
The Bogoliubov-de Gennes equations are solved for an inhomogeneous condensate in the vicinity of a turning point, addressing the full continuous spectrum. A basis change in the spa…
Electromagnetic Response of the Electron Gas and the Thermal Casimir Pressure Anomaly
Carsten Henkel
A review of the nonlocal electromagnetic response functions for the degenerate electron gas, computed within standard perturbation theory, is given. These expressions due to Lindha…
