Classical and quantum behavior of the harmonic and the quartic oscillators
David Brizuela
In a previous paper a formalism to analyze the dynamical evolution of classical and quantum probability distributions in terms of their moments was presented. Here the application…
Statistical moments for classical and quantum dynamics: formalism and generalized uncertainty relations
David Brizuela
The classical and quantum evolution of a generic probability distribution is analyzed. To that end, a formalism based on the decomposition of the distribution in terms of its stati…
Improved Quantum Magnetometry beyond the Standard Quantum Limit
J. B. Brask, R. Chaves, J. Kolodynski
Under ideal conditions, quantum metrology promises a precision gain over classical techniques scaling quadratically with the number of probe particles. At the same time, no-go resu…
Interaction induced Landau-Zener transitions
Jonas Larson
By considering a quantum critical Lipkin-Meshkov-Glick model we analyze a new type of Landau-Zener transitions where the population transfer is mediated by interaction rather than…
Dicke-type phase transition in a multimode optomechanical system
Jesse Mumford, D. H. J. O'Dell, Jonas Larson
We consider the "membrane in the middle" optomechanical model consisting of a laser pumped cavity which is divided in two by a flexible membrane that is partially transmissive to l…
