Scaling and non-Abelian signature in fractional quantum Hall quasiparticle tunneling amplitude

Zi-Xiang Hu, Ki Hoon Lee, E. H. Rezayi +2

We study the scaling behavior in the tunneling amplitude when quasiparticles tunnel along a straight path between the two edges of a fractional quantum Hall annulus. Such scaling b…

Level crossings and zero-field splitting in the \{Cr\}-cubane spin-cluster by inelastic neutron scattering and magnetization studies

D. Vaknin, V. O. Garlea, F. Demmel +10

Inelastic neutron scattering in variable magnetic field and high-field magnetization measurements, at the milikelvin temperature range, were performed to gain insight into the low-…

Topological origin of subgap conductance in insulating bilayer graphene

Jian Li, Ivar Martin, Markus Buttiker +1

The edges of graphene-based systems possess unusual electronic properties, originating from the non-trivial topological structure associated to the pseudo-spinorial character of th…

Spin transition in GdN@C, detected by low-temperature on-chip SQUID technique

L. Chen, E. E. Carpenter, C. S. Hellberg +4

We present a magnetic study of the GdN@C molecule, consisting of a Gd-trimer via a Nitrogen atom, encapsulated in a C cage. This molecular system can be an effici…

Conductivity of interacting massless Dirac particles in graphene: Collisionless regime

Vladimir Juricic, Oskar Vafek, Igor F. Herbut

We provide detailed calculation of the a.c. conductivity in the case of 1/r-Coulomb interacting massless Dirac particles in graphene in the collisionless limit when ω>> T. The anal…

On-chip SQUID measurements in the presence of high magnetic fields

L. Chen, W. Wernsdorfer, C. Lampropoulos +2

We report a low temperature measurement technique and magnetization data of a quantum molecular spin, by implementing an on-chip SQUID technique. This technique enables the SQUID m…

Magnetic anisotropy in thin films of Prussian blue analogues

D. M. Pajerowski, J. E. Gardner, M. J. Andrus +6

The magnetic anisotropy of thin (~ 200 nm) and thick (~ 2 m) films and of polycrystalline (diameters ~ 60 nm) powders of the Prussian blue analogue RbNi[Cr(CN)$_…

Adiabatic Cooling with Non-Abelian Anyons

G. Gervais, Kun Yang

We show in this Letter that the ground state degeneracy associated with the presence of non-Abelian anyons can be probed by using an adiabatic cooling process based on the non-Abel…

Magnetic strong coupling in a spin-photon system and transition to classical regime

I. Chiorescu, N. Groll, S. Bertaina +2

We study the energy level structure of the Tavis-Cumming model applied to an ensemble of independent magnetic spins coupled to a variable number of photons. Rabi splittings…

Orbital order in bilayer graphene at filling factor

R. Côté, Jules Lambert, Yafis Barlas +1

In a graphene bilayer with Bernal stacking both and orbital Landau levels have zero kinetic energy. An electronic state in the N=0 Landau level consequently has three q…

Two-dimensional Dirac fermions in a topological insulator: transport in the quantum limit

J. G. Analytis, R. D. McDonald, S. C. Riggs +3

Pulsed magnetic fields of up to 55T are used to investigate the transport properties of the topological insulator Bi_2Se_3 in the extreme quantum limit. For samples with a bulk car…
