Resistively Detected NMR in Quantum Hall States: Investigation of the anomalous lineshape near

C. R. Dean, B. A. Piot, L. N. Pfeiffer +2

A study of the resistively detected nuclear magnetic resonance (RDNMR) lineshape in the vicinity of was performed on a high-mobility 2D electron gas formed in GaAs/AlGaAs. In…

Universal quantized spin-Hall conductance fluctuation in graphene

Z. H. Qiao, J. Wang, Y. D. Wei +1

We report a theoretical investigation of quantized spin-Hall conductance fluctuation of graphene devices in the diffusive regime. Two graphene models that exhibit quantized spin-Ha…

Two level anti-crossings high up in the single-particle energy spectrum of a quantum dot

C. Payette, D. G. Austing, G. Yu +5

We study the evolution with magnetic field of the single-particle energy levels high up in the energy spectrum of one dot as probed by the ground state of the adjacent dot in a wea…

Magnetic field induced effects in the high source-drain bias current of weakly coupled vertical quantum dot molecules

D. G. Austing, C. Payette, G. Yu +1

We report on the basic properties of recently observed magnetic field resonance, induced time dependent oscillation, and hysteresis effects in the current flowing through two weakl…

Shot Noise in SU(N) Quantum Dot Kondo Effects

P. Vitushinsky, A. A. Clerk, K. Le Hur

We study shot noise in the current of quantum dots whose low-energy behaviour corresponds to an SU(N) Kondo model, focusing on the case N=4 relevant to carbon nanotube dots. For ge…

Quantum Theory of Cavity-Assisted Sideband Cooling of Mechanical Motion

Florian Marquardt, Joe P. Chen, A. A. Clerk +1

We present a fully quantum theory describing the cooling of a cantilever coupled via radiation pressure to an illuminated optical cavity. Applying the quantum noise approach to the…

Quantum inductance and negative electrochemical capacitance at finite frequency

J. Wang, B. G. Wang, H. Guo

We report on theoretical investigations of frequency dependent quantum capacitance. It is found that at finite frequency a quantum capacitor can be characterized by a classical RLC…
