Phonon-bottleneck enhanced magnetic hysteresis in a molecular paddle wheel complex of Ru

L. Chen, C. M. Ramsey, N. S. Dalal +4

The ruthenium based molecular magnet [Ru(D(3,5-ClPh)F)Cl(0.5HO)CH] (hereafter Ru) behaves as a two-level system at sufficiently low temperatu…

Infinite-Randomness Fixed Points for Chains of Non-Abelian Quasiparticles

N. E. Bonesteel, Kun Yang

One-dimensional chains of non-Abelian quasiparticles described by Chern-Simons-Witten theory can enter random singlet phases analogous to that of a random chain of ordina…

Domain wall type defects as anyons in phase space

Alexander Seidel, Dung-Hai Lee

We discuss how the braiding properties of Laughlin quasi-particles in quantum Hall states can be understood within a one-dimensional formalism we proposed earlier. In this formalis…

Edge Excitations and Non-Abelian Statistics in the Moore-Read State: A Numerical Study in the Presence of Coulomb Interaction and Edge Confinement

Xin Wan, Kun Yang, E. H. Rezayi

We study the ground state and low-energy excitations of fractional quantum Hall systems on a disk at filling fraction , with Coulomb interaction and background confining po…

Disorder mediated splitting of the cyclotron resonance in two-dimensional electron systems

E. A. Henriksen, S. Syed, Y. -J. Wang +3

We perform a direct study of the magnitude of the anomalous splitting in the cyclotron resonance (CR) of a two-dimensional electron system (2DES) as a function of sample disorder.…

High-Performance, Hysteresis-Free Carbon Nanotube FETs via Directed Assembly

S. A. McGill, S. G. Rao, P. Manandhar +2

High-performance single-wall carbon nanotube field-effect transistors (SWNT-FETs) are fabricated using directed assembly and mass-produced carbon nanotubes (CNTs). These FETs exhib…

Collective Modes and Skyrmion Excitations in Graphene SU(4) Quantum Hall Ferromagnets

Kun Yang, S. Das Sarma, A. H. MacDonald

Graphene exhibits quantum Hall ferromagnetism in which an approximate SU(4) symmetry involving spin and valley degrees of freedom is spontaneously broken. We construct a set of int…
