Quantum Friction in Arbitrarily Directed Motion
J. Klatt, M. B. Farias, D. A. R. Dalvit +1
Quantum friction, the electromagnetic fluctuation-induced frictional force decelerating an atom which moves past a macroscopic dielectric body, has so far eluded experimental evide…
Casimir-Polder shifts on quantum levitation states
P. -P. Crépin, G. Dufour, R. Guérout +2
An ultracold atom above a horizontal mirror experiences quantum reflection from the attractive Casimir-Polder interaction, which holds it against gravity and leads to quantum levit…
Regularity and chaos in cavity QED
M. A. Bastarrachea-Magnani, B. López-del-Carpio, J. Chávez-Carlos +2
The interaction of a quantized electromagnetic field in a cavity with a set of two-level atoms inside can be described with algebraic Hamiltonians of increasing complexity, from th…
Measuring correlations of cold atom systems using multiple quantum probes
Michael Streif, Andreas Buchleitner, Dieter Jaksch +1
We present a non-destructive method to probe a complex quantum system using multiple impurity atoms as quantum probes. Our protocol provides access to different equilibrium propert…
Local probe of single phonon dynamics in warm ion crystals
Ahmed Abdelrahman, Omid Khosravani, Manuel Gessner +8
The detailed characterization of non-trivial coherence properties of composite quantum systems of increasing size is an indispensable prerequisite for scalable quantum computation,…
Distinguishing models of surface response through the self-energy of an electron
Robert Bennett, Stefan Yoshi Buhmann, Claudia Eberlein
The self-energy of an electron confined between parallel surfaces with arbitrary dielectric properties is calculated. The mechanism for this effect is the surface-induced modificat…
