Real space first-principles derived semiempirical pseudopotentials applied to tunneling magnetoresistance

K. H. Bevan, Tony Low, H. Guo

In this letter we present a real space density functional theory (DFT) localized basis set semi-empirical pseudopotential (SEP) approach. The method is applied to iron and magnesiu…

Introduction to Quantum Noise, Measurement and Amplification

A. A. Clerk, M. H. Devoret, S. M. Girvin +2

The topic of quantum noise has become extremely timely due to the rise of quantum information physics and the resulting interchange of ideas between the condensed matter and AMO/qu…

Conductance spectra of metallic nanotube bundles

Wei Ren, C. T. Chan, T. H. Cho +4

We report a first principles analysis of electronic transport characteristics for (n,n) carbon nanotube bundles. When n is not a multiple of 3, inter-tube coupling causes universal…

Contrasting Behavior of the 5/2 and 7/3 Fractional Quantum Hall Effect in a Tilted Field

C. R. Dean, B. A. Piot, P. Hayden +4

Using a tilted field geometry, the effect of an in-plane magnetic field on the even denominator nu = 5/2 fractional quantum Hall state is studied. The energy gap of the nu = 5/2 st…

Entanglement Dynamics in a Dispersively Coupled Qubit-Oscillator System

D. W. Utami, A. A. Clerk

We study entanglement dynamics in a system consisting of a qubit dispersively coupled to a finite-temperature, dissipative, driven oscillator. We show that there are two generic wa…

Full counting statistics and conditional evolution in a nanoelectromechanical system

S. D. Bennett, A. A. Clerk

We study theoretically the full distribution of transferred charge in a tunnel junction (or quantum point contact) coupled to a nanomechanical oscillator, as well as the conditiona…

Back-action evasion and squeezing of a mechanical resonator using a cavity detector

A. A. Clerk, F. Marquardt, K. Jacobs

We study the quantum measurement of a cantilever using a parametrically-coupled electromagnetic cavity which is driven at the two sidebands corresponding to the mechanical motion.…

Quantum-limited mass flow of liquid He

G. Lambert, G. Gervais, W. J. Mullin

We consider theoretically the possibility of observing unusual quantum fluid behavior in liquid He and solutions of He in He systems confined to nano-channels. In…

Intrinsic Gap of the nu=5/2 Fractional Quantum Hall State

C. R. Dean, B. A. Piot, P. Hayden +4

The fractional quantum Hall effect is observed at low field, in a regime where the cyclotron energy is smaller than the Coulomb interaction. The nu=5/2 excitation gap is measured t…
