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…
Topologically protected mobile solid He on carbon nanotube
Igor Todoshchenko, Masahiro Kamada, Jukka-Pekka Kaikkonen +7
Low dimensional fermionic quantum systems are exceptionally interesting because they reveal distinctive physical phenomena, including among others, topologically protected excitati…
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…
Graphene resonator as an ultrasound detector for generalized Love waves in a polymer film with two level states
Antti Laitinen, Jukka-Pekka Kaikkonen, Thanniyil S. Abhilash +6
We have investigated surface shear waves at 22 MHz in a 0.5-micron-thick polymer film on SiO2/Si substrate at low temperatures using suspended and non-suspended graphene as detecto…
Dry transfer method for suspended graphene on lift-off-resist: simple ballistic devices with Fabry-Pérot interference
Ying Liu, T. S. Abhilash, Antti Laitinen +3
We demonstrate a fabrication scheme for clean suspended structures using chemical-vapor-deposition-grown graphene and a dry transfer method on lift-off-resist-coated substrates to…
Defects in h-BN tunnel barrier for local electrostatic probing of two dimensional materials
Ying Liu, Zhenbing Tan, Manohar Kumar +3
Defects in hexagonal boron nitride (h-BN) layer can facilitate tunneling current through thick h-BN tunneling barriers. We have investigated such current-mediating defects as local…

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…
Breakdown of zero-energy quantum Hall state in graphene in the light of current fluctuations and shot noise
Antti Laitinen, Manohar Kumar, Teemu Elo +3
We have investigated the cross-over from Zener tunneling of single charge carriers to avalanche type of bunched electron transport in a suspended graphene Corbino disk in the zerot…
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…
Nanoscale electromechanics to measure thermal conductivity, expansion and interfacial losses
John P. Mathew, Raj Patel, Abhinandan Borah +3
We study the effect of localized Joule heating on the mechanical properties of doubly clamped nanowires under tensile stress. Local heating results in systematic variation of the r…
Low-power photothermal self-oscillation of bimetallic nanowires
Roberto De Alba, T. S. Abhilash, Richard Rand +2
We investigate the nonlinear mechanics of a bimetallic, optically absorbing SiN-Nb nanowire in the presence of incident laser light and a reflecting Si mirror. Situated in a standi…
