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…
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…
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…
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…
