Temperature-invariant Casimir-Polder forces despite large thermal photon numbers
Simen A. Ellingsen, Stefan Yoshi Buhmann, Stefan Scheel
We demonstrate that Casimir-Polder potentials can be entirely independent of temperature even when allowing for the thermal photon numbers to become large at the relevant molecular…
Temperature Correction to Casimir-Lifshitz Free Energy at Low Temperatures: Semiconductors
Simen A. Ellingsen, Iver Brevik, Johan S. Høye +1
The Casimir force and free energy at low temperatures has been the subject of focus for some time. We calculate the temperature correction to the Casimir-Lifshitz free energy betwe…
Frequency spectrum of the Casimir force: interpretation and a paradox
Simen A. Ellingsen
The frequency spectrum of the Casimir force between two plates separated by vacuum as it appears in the Lifshitz formalism is reexamined and generalised as compared to previous wor…
Concerning verification of the Nernst theorem for Casimir-Lifshitz free energy
Simen A. Ellingsen
By regarding the Lifshitz expression for the Casimir free energy on the real frequency axis rather than the imaginary Matsubara frequencies as is customary, new light is shed on th…
