Detecting quantum-coherent nanomechanical oscillations using the current-noise spectrum of a double quantum dot
Neill Lambert, Franco Nori
We consider a nanomechanical resonator coupled to a double quantum dot. We demonstrate how the finite-frequency current noise spectrum through the double quantum dot can be used to…

Entanglement in quantum catastrophes
Clive Emary, Neill Lambert, Tobias Brandes
We classify entanglement singularities for various two-mode bosonic systems in terms of catastrophe theory. Employing an abstract phase-space representation, we obtain exact result…

Entanglement and the Phase Transition in Single Mode Superradiance
Neill Lambert, Clive Emary, Tobias Brandes
We consider the entanglement properties of the quantum phase transition in the single-mode superradiance model, involving the interaction of a boson mode and an ensemble of atoms.…
