Noise spectrum of a tunnel junction coupled to a nanomechanical oscillator
J. Wabnig, J. Rammer, A. L. Shelankov
A nanomechanical resonator coupled to a tunnel junction is studied. The oscillator modulates the transmission of the junction, changing the current and the noise spectrum. The infl…
Statistics of charge transfer in a tunnel junction coupled to an oscillator
J. Wabnig, D. V. Khomitsky, J. Rammer +1
The charge transfer statistics of a tunnel junction coupled to a quantum object is studied using the charge projection technique. The joint dynamics of the quantum object and the n…
Quantum measurement in the charge representation
J. Rammer, A. L. Shelankov, J. Wabnig
Counting statistics of charge transfers in a point contact interacting with an arbitrary quantum system is studied. The theory for the charge specific density matrix is developed,…
Self-consistent theory of dynamic melting of a vortex lattice
Staffan Grundberg, Jørgen Rammer
The dynamic melting of vortex lattices in type II superconductors is considered. A field-theoretic formulation of the pinning problem allows the average over the quenched disorder…
Weak and Strong Localization in Low-Dimensional Semiconductor Structures
S. -R. Eric Yang, J. Rammer
The dependence of the localization length on the number of occupied subbands in low-dimensional semiconductors is investigated. The localization length is shown to be proportio…
