Amplification of the quantum superposition macroscopicity of a flux qubit by a magnetized Bose gas
T. J. Volkoff, Uwe R. Fischer
We calculate a measure of superposition macroscopicity for a superposition of screening current states in a superconducting flux qubit (SFQ), by relating $\mathcal{M}…

"Photonic" cat states from strongly interacting matter waves
Uwe R. Fischer, Myung-Kyun Kang
We consider ultracold quantum gases of scalar bosons, residing in a coupling strength--density regime in which they constitute a twofold fragmented condensate trapped in a single w…

Intrinsic measurement errors for the speed of light in vacuum
Daniel Braun, Fabienne Schneiter, Uwe R. Fischer
The speed of light in vacuum, one of the most important and precisely measured natural constants, is fixed by convention to m/s. Advanced theories predict possible…
