Superfluid He as a rigorous test bench for different damping models in nanoelectromechanical resonators
Timo Kamppinen, Jere T. Mäkinen, Vladimir B. Eltsov
We have used nanoelectromechanical resonators to probe superfluid He at different temperature regimes, spanning over four orders of magnitude in damping. These regimes are char…
Dimensional control of tunneling two level systems in nanoelectromechanical resonators
T. Kamppinen, J. T. Mäkinen, V. B. Eltsov
Tunneling two level systems affect damping, noise and decoherence in a wide range of devices, including nanoelectromechanical resonators, optomechanical systems, and qubits. Theore…
Topological nodal line in superfluid He and the Anderson theorem
T. Kamppinen, J. Rysti, M. -M. Volard +2
Superconductivity and superfluidity with anisotropic pairing -- such as -wave in cuprates and -wave in superfluid He -- are strongly suppressed by impurities. Meanwhile,…
Suppressing the Kibble-Zurek mechanism by a symmetry-violating bias
J. Rysti, J. T. Mäkinen, S. Autti +3
The formation of topological defects in continuous phase transitions is driven by the Kibble-Zurek mechanism. Here we study the formation of single- and half-quantum vortices durin…
Nanomechanical resonators for cryogenic research
T. Kamppinen, V. B. Eltsov
Suspended aluminium nanoelectromechanical resonators have been fabricated, and the manufacturing process is described in this work. Device motion is driven and detected with a magn…
