Critical superflows and thermodynamic instabilities in superfluids

B Goutéraux, F Sottovia, E Mefford - Physical Review D, 2023 - APS
In this work, we study the linear stability of superfluid phases of matter irrespective of the
nature of microscopic degrees of freedom and the strength of interactions between them …

Piezoelectric effect and diode effect in anapole and monopole superconductors

M Chazono, S Kanasugi, T Kitamura, Y Yanase - Physical Review B, 2023 - APS
Superconductors lacking both inversion symmetry and time-reversal symmetry have been
attracting much attention as a platform for exotic superconducting phases and anomalous …

Rotating quantum wave turbulence

JT Mäkinen, S Autti, PJ Heikkinen, JJ Hosio… - Nature physics, 2023 - nature.com
Turbulence under strong influence of rotation is described as an ensemble of interacting
inertial waves across a wide range of length scales. In macroscopic quantum condensates …

Transport of bound quasiparticle states in a two-dimensional boundary superfluid

S Autti, RP Haley, A Jennings, GR Pickett… - Nature …, 2023 - nature.com
The B phase of superfluid 3He can be cooled into the pure superfluid regime, where the
thermal quasiparticle density is negligible. The bulk superfluid is surrounded by a quantum …

Surface State Dissipation in Confined

AJ Shook, E Varga, I Boettcher, JP Davis - Physical Review Letters, 2024 - APS
We have studied the power dependence of superfluid Helmholtz resonators in flat (750 and
1800 nm) rectangular channels. In the A phase of superfluid He 3, we observe a nonlinear …

Vortex-bound solitons in topological superfluid 3He

JT Mäkinen, K Zhang, VB Eltsov - Journal of Physics: Condensed …, 2023 - iopscience.iop.org
The different superfluid phases of 3 He are described by p-wave order parameters that
include anisotropy axes both in the orbital and spin spaces. The anisotropy axes …

Bogoliubov Fermi surfaces in spin- systems: Model Hamiltonians and experimental consequences

C Setty, Y Cao, A Kreisel, S Bhattacharyya… - Physical Review B, 2020 - APS
Bogoliubov Fermi surfaces (BFSs) are topologically protected regions of zero energy
excitations in a superconductor whose dimension equals that of the underlying normal state …

Vortices in Polar and β Phases of 3He

GE Volovik - JETP Letters, 2022 - Springer
Recently, a new topological phase of superfluid 3He called the β phase has been obtained
by strong polarization of the nematic polar phase. We consider half-quantum vortices, which …

Symmetry, nodal structure, and Bogoliubov Fermi surfaces for nonlocal pairing

C Timm, A Bhattacharya - Physical Review B, 2021 - APS
Multiband effects can lead to fundamentally different electronic behavior of solids, as
exemplified by the possible emergence of Fermi surfaces of Bogoliubov quasiparticles in …
