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…
Disentangling the sources of ionizing radiation in superconducting qubits
L. Cardani, I. Colantoni, A. Cruciani +27
Radioactivity was recently discovered as a source of decoherence and correlated errors for the real-world implementation of superconducting quantum processors. In this work, we mea…
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…
Phase Change Memory by GeSbTe Electrodeposition in Crossbar Arrays
Yasir J Noori, Lingcong Meng, Ayoub H. Jaafar +12
Phase change memories (PCM) is an emerging type of non-volatile memory that has shown a strong presence in the data-storage market. This technology has recently attracted significa…
Lateral electrodeposition of MoS2 semiconductor over an insulator
Nema Abdelazim, Yasir J Noori, Shibin Thomas +10
Developing novel techniques for depositing transition metal dichalcogenides is crucial for the industrial adoption of 2D materials in optoelectronics. In this work, the lateral gro…
Path-Dependent Supercooling of the He Superfluid A-B transition
Dmytro Lotnyk, Anna Eyal, Nikolay Zhelev +7
We examine the discontinuous first-order superfluid He A to B transition in the vicinity of the polycritical point (2.232 mK and 21.22 bar). We find path-dependent transitions:…
Thermal transport of helium-3 in a strongly confining channel
D. Lotnyk, A. Eyal, N. Zhelev +8
In a neutral system such as liquid helium-3, transport of mass, heat, and spin provide information analogous to electrical counterparts in metals, superconductors and topological m…
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…
Evidence for a Spatially-Modulated Superfluid Phase of He under Confinement
Lev V. Levitin, Ben Yager, Laura Sumner +6
In superfluid He-B confined in a slab geometry, domain walls between regions of different order parameter orientation are predicted to be energetically stable. Formation of the…
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…
Transfer Printing of CVD Graphene FETs on Patterned Substrates
T. S. Abhilash, Roberto De Alba, Nikolay Zhelev +2
We describe a simple and scalable method for the transfer of CVD graphene for the fabrication of field effect transistors. This is a dry process that uses a modified RCA cleaning s…
Breather decay into a vortex/anti-vortex pair in a Josephson Ladder
K. Segall, P. Williams, O. Svitelskiy +4
We present experimental evidence for a new behavior which involves discrete breathers and vortices in a Josephson Ladder. Breathers can be visualized as the creation and subsequent…
Study of superfluid He under nanoscale confinement. A new approach to the investigation of superfluid He films
Lev Levitin, Robert Bennett, Andrew Casey +7
We review recent experiments in which superfluid He has been studied under highly controlled confinement in nanofluidic sample chambers. We discuss the experimental challenges…
Dissipation signatures of the normal and superfluid phases in torsion pendulum experiments with 3He in aerogel
