A nanomechanical resonator shuttling single electrons at radio frequencies
A. Erbe, C. Weiss, W. Zwerger +1
We observe transport of electrons through a metallic island on the tip of a nanomechanical pendulum. The resulting tunneling current shows distinct features corresponding to the di…
Critical Velocity of Superfluid Flow past Large Obstacles in Bose-Condensates
J. S. Stiessberger, W. Zwerger
By considering the stability of potential flow of a superfluid around large obstacles of size R, we derive an analytical result for the critical velocity which is of order v_c \sim…
Optical detection of a BCS transition of Lithium-6 in harmonic traps
F. Weig, W. Zwerger
We study the detection of a BCS transition within a sample of Lithium--6 atoms confined in a harmonic trap. Using the local density approximation we calculate the pair correlation…
Quantum fluctuations in the cohesive force of metallic nanowires
C. Hoeppler, W. Zwerger
Based on the recent free electron model for cohesion in narrow metallic constrictions by Stafford et al., we calculate the quantum fluctuations in the cohesive force versus elongat…
