Magnetic Confinement of a Bubble of Supercooled He-A
Luke Whitehead, Andrew Casey, Richard P. Haley +9
We have designed and constructed a magnet surrounding a cylindrical volume of superfluid helium-3 to isolate a region of metastable, supercooled A-phase, entirely surrounded by bul…
Odd-parity superconductivity underpinned by antiferromagnetism in heavy fermion metal YbRhSi
Lev V. Levitin, Jan Knapp, Petra Knappová +13
Topological superconductors are essential elements of the periodic table of topological quantum matter. However, the relevant odd-parity spin-triplet superconductors are rare. We r…
Chiral superfluid helium-3 in the quasi-two-dimensional limit
Petri J. Heikkinen, Lev V. Levitin, Xavier Rojas +8
Anisotropic pair breaking close to surfaces favors the chiral A phase of the superfluid He over the time-reversal invariant B phase. Confining the superfluid He into a cavi…
Nanofluidic platform for studying the first-order phase transitions in superfluid helium-3
Petri J. Heikkinen, Nathan Eng, Lev V. Levitin +9
The symmetry-breaking first-order phase transition between superfluid phases He-A and He-B can be triggered extrinsically by ionising radiation or heterogeneous nucleation…
Long nanomechanical resonators with circular cross-section
Samuli Autti, Andrew Casey, Marie Connelly +23
Fabrication of superconducting nanomechanical resonators for quantum research, detectors and devices traditionally relies on a lithographic process, resulting in oscillators with s…
Fragility of surface states in topological superfluid He
P. J. Heikkinen, A. Casey, L. V. Levitin +6
Topological superfluid He, with unconventional spin-triplet p-wave pairing, provides a model system for topological superconductors, which have attracted significant interest t…
Fabrication of micro fluidic cavities using Si-to-glass anodic bonding
N. Zhelev, T. S. Abhilash, R. G. Bennett +7
We demonstrate the fabrication of 1.08 m deep microfluidic cavities with characteristic size as large as 7 mm 11 mm or 11 mm diameter, using a siliconglass ano…
Current Sensing Noise Thermometry: A fast practical solution to low temperature measurement
Andrew Casey, Frank Arnold, Lev V. Levitin +9
We describe the design and performance of a series of fast, precise current sensing noise thermometers. The thermometers have been fabricated with a range of resistances from 1.290…
Quantum transport in mesoscopic He films: experimental study of the interference of bulk and boundary scattering
P. Sharma, A. Córcoles, R. G. Bennett +4
We discuss the mass transport of a degenerate Fermi liquid He film over a rough surface, and the film momentum relaxation time, in the framework of theoretical predictions. In…
