Operating Nanobeams in a Quantum Fluid
D. I. Bradley, R. George, A. M. Guenault +12
Microelectromechanical (MEMS) and nanoelectromechanical systems (NEMS) are ideal candidates for exploring quantum fluids since they can be manufactured reproducibly, cover the freq…
On-chip magnetic cooling of a nanoelectronic device
D. I. Bradley, A. M. Guénault, D. Gunnarsson +8
We demonstrate significant cooling of electrons in a nanostructure below 10 mK by demagnetisation of thin-film copper on a silicon chip. Our approach overcomes the typical bottlene…
Breaking the superfluid speed limit
D. I. Bradley, S. N. Fisher, A. M. Guénault +7
Coherent condensates appear as emergent phenomena in many systems, sharing the characteristic feature of an energy gap separating the lowest excitations from the condensate ground…
Probing Bogoliubov quasiparticles in superfluid He with a 'vibrating-wire like' MEMS device
M. Defoort, S. Dufresnes, S. L. Ahlstrom +11
We have measured the interaction between superfluid He-B and a micro-machined goalpost-shaped device at temperatures below . The measured damping follows well the the…
Nanoelectronic thermometers optimised for sub-10 millikelvin operation
J. R. Prance, D. I. Bradley, R. E. George +8
We report the cooling of electrons in nanoelectronic Coulomb blockade thermometers below 4 mK. Above 7 mK the devices are in good thermal contact with the environment, well isolate…
The Generation, Evolution and Decay of Pure Quantum Turbulence: A Full Biot-Savart Simulation
Shoji Fujiyama, Akira Mitani, Makoto Tsubota +6
A zero temperature superfluid is arguably the simplest system in which to study complex fluid dynamics, such as turbulence. We describe computer simulations of such turbulence and…
