Bipartite entanglement under frequency comb pumping in parametric Josephson circuits
Mikael Vartiainen, Ilari Lilja, Ekaterina Mukhanova +3
The creation of high-quality cluster states in superconducting microwave circuits is a relevant ingredient in continuous-variable quantum computing. Although large-scale cluster st…
Evidence for magnetic crystallization waves at the surface of He crystal
Igor Todoshchenko, Alexander Savin, Pertti J. Hakonen
Ultralow temperature crystals of the helium isotopes He and He are intriguing quantum systems. Deciphering the complex features of these unusual materials has been made pos…
Mapping the topological proximity-induced gap of multiterminal Josephson junctions
Maxwell Wisne, Yanpei Deng, Markus Lilja +2
Multiterminal Josephson junctions (MTJJs), devices in which a normal metal is in contact with three or more superconducting leads, have been proposed as artificial analogs of topol…
Quantum degeneracy in mesoscopic matter: Casimir effect and Bose-Einstein condensation
I. Todoshchenko, M. Kamada, J. -P. Kaikkonen +5
The ground-state phonon pressure is an analogue to the famous Casimir pressure of vacuum produced by zero-point photons. The acoustic Casimir forces are, however, many orders of ma…
Spectroscopy of oscillation modes in homogeneously precessing domain of superfluid He-B
V. V. Zavjalov, A. Savin, E. Sergeicheva +1
We study Homogeneously Precessing Domain (HPD) in superfluid He-B in a regular continuous-wave nuclear magnetic resonance (CW NMR) experiment. Using Fourier analysis of CW NMR…
Quartz tuning fork as a probe of surface waves
Igor Todoshchenko, Alexander Savin, Miika Haataja +2
Quartz tuning forks are high-quality mechanical oscillators widely used in low temperature physics as viscometers, thermometers and pressure sensors. We demonstrate that a fork pla…
