A Sub-kHz Mechanical Resonator Passively Cooled to 6 mK
Loek van Everdingen, Jaimy Plugge, Tim Fuchs +6
Highly coherent mechanical resonators are invaluable to ultrasensitive detection techniques by enabling detection of small forces. Studying mechanical resonators in a thermal equil…

Superconducting flux concentrator coils for levitation of particles in the Meissner state
Robert Smit, Martijn Janse, Eli van der Bent +5
Magnetic levitation of superconductors is a promising platform to study quantum mechanics in the large-mass limit. One major limitation is the weak trapping potential, which result…

Current experimental upper bounds on spacetime diffusion
Martijn Janse, Dennis G. Uitenbroek, Loek van Everdingen +3
A consistent theory describing the dynamics of quantum systems interacting on a classical space-time was recently put forward by Oppenheim et al..[1, 2]. Quantum states may retain…
