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…
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…
Precise Calorimetry of Small Metal Samples Using Noise Thermometry
Jan Knapp, Lev V. Levitin, Ján Nyéki +2
We describe a compact calorimeter that opens ultra-low temperature heat capacity studies of small metal crystals in moderate magnetic fields. The performance is demonstrated on the…
A-B transition in superfluid He and cosmological phase transitions
Mark Hindmarsh, J. A. Sauls, Kuang Zhang +10
First order phase transitions in the very early universe are a prediction of many extensions of the Standard Model of particle physics and could provide the departure from equilibr…
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…
Supercooling of the A phase of He
Yefan Tian, Dmytro Lotnyk, Anna Eyal +9
Because of the extreme purity, lack of disorder, and complex order parameter, the first-order superfluid He A-B transition is the leading model system for first order transitio…
Effect of Rough Walls on Transport in Mesoscopic He Films
Priya Sharma, Antonio Corcoles, R. G. Bennett +3
The interplay of bulk and boundary scattering is explored in a regime where quantum size effects modify mesoscopic transport in a degenerate Fermi liquid film of He on a rough…
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…
The A-B transition in superfluid 3He under confinement in a thin slab geometry
N. Zhelev, T. S. Abhilash, E. N. Smith +5
The influence of confinement on the topological phases of superfluid 3He is studied using the torsional pendulum method. We focus on the phase transition between the chiral A-phase…
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…
