Observation of Anomalous Decay of a Polarized Three-Component Fermi Gas
Grant L. Schumacher, Jere T. Mäkinen, Yunpeng Ji +5
Systems of fermions with multiple internal states, such as quarks in quantum chromodynamics and nucleons in nuclear matter, are at the heart of some of the most complex quantum man…
Vortex-bound solitons in topological superfluid He
J. T. Mäkinen, K. Zhang, V. B. Eltsov
The different superfluid phases of He are described by -wave order parameters that include anisotropy axes both in the orbital and spin spaces. The anisotropy axes character…
On the Stability of the Repulsive Fermi Gas with Contact Interactions
Yunpeng Ji, Grant L. Schumacher, Gabriel G. T. Assumpção +4
We report the creation and the study of the stability of a repulsive quasi-homogeneous spin- Fermi gas with contact interactions. For the range of scattering lengths explo…
Rotating quantum wave turbulence
J. T. Mäkinen, S. Autti, P. J. Heikkinen +6
Rotating turbulence is ubiquitous in nature. Previous works suggest that such turbulence could be described as an ensemble of interacting inertial waves across a wide range of leng…
Dimensional control of tunneling two level systems in nanoelectromechanical resonators
T. Kamppinen, J. T. Mäkinen, V. B. Eltsov
Tunneling two level systems affect damping, noise and decoherence in a wide range of devices, including nanoelectromechanical resonators, optomechanical systems, and qubits. Theore…
Nonlinear two-level dynamics of quantum time crystals
Samuli Autti, Petri J Heikkinen, Jaakko Nissinen +4
A time crystal is a macroscopic quantum system in periodic motion in its ground state, stable only if isolated from energy exchange with the environment. For this reason, coupling…
Suppressing the Kibble-Zurek mechanism by a symmetry-violating bias
J. Rysti, J. T. Mäkinen, S. Autti +3
The formation of topological defects in continuous phase transitions is driven by the Kibble-Zurek mechanism. Here we study the formation of single- and half-quantum vortices durin…
Mutual friction in superfluid He-B in the low-temperature regime
J. T. Mäkinen, V. B. Eltsov
We measure the response of a rotating sample of superfluid He-B to spin-down to rest in the zero-temperature limit. Deviations from perfect cylindrical symmetry in the flow env…
Bose-Einstein condensation of magnons and spin superfluidity in the polar phase of He
S. Autti, V. V. Dmitriev, J. T. Mäkinen +5
The polar phase of He, which is topological spin-triplet superfluid with the Dirac nodal line in the spectrum of Bogolubov quasiparticles, has been recently stabilized in a nan…
No Effect of Steady Rotation on Solid He in a Torsional Oscillator
M. J. Fear, P. M. Walmsley, D. E. Zmeev +2
We have measured the response of a torsional oscillator containing polycrystalline hcp solid He to applied steady rotation in an attempt to verify the observations of several…
Observation of half-quantum vortices in topological superfluid 3He
S. Autti, V. V. Dmitriev, J. T. Mäkinen +5
One of the most sought-after objects in topological quantum matter systems is a vortex carrying half a quantum of circulation. They were originally predicted to exist in superfluid…
Andreev reflection in rotating superfluid He-B
V. B. Eltsov, J. J. Hosio, M. Krusius +1
Andreev reflection of quasiparticle excitations from quantized line vortices is reviewed in the isotropic B phase of superfluid He in the temperature regime of ballistic quasip…
Propagation of thermal excitations in a cluster of vortices in superfluid 3He-B
J. J. Hosio, V. B. Eltsov, R. de Graaf +3
We describe the first measurement on Andreev scattering of thermal excitations from a vortex configuration with known density, spatial extent, and orientations in 3He-B superfluid.…
