Analogue of cosmological particle creation in an ion trap
Ralf Schützhold, Michael Uhlmann, Lutz Petersen +3
We study phonons in a dynamical chain of ions confined by a trap with a time-dependent (axial) potential strength and demonstrate that they behave in the same way as quantum fields…
Aspects of Cosmic Inflation in Expanding Bose-Einstein Condensates
Michael Uhlmann, Yan Xu, Ralf Schützhold
Phonons in expanding Bose-Einstein condensates with wavelengths much larger than the healing length behave in the same way as quantum fields within a universe undergoing an acceler…
Resonant cavity photon creation via the dynamical Casimir effect
Michael Uhlmann, Günter Plunien, Ralf Schützhold +1
Motivated by a recent proposal for an experimental verification of the dynamical Casimir effect, the macroscopic electromagnetic field within a perfect cavity containing a thin sla…
