Avoided crossing and sub-Fourier sensitivity in driven quantum systems
David Cubero, Gordon R. M. Robb, Ferruccio Renzoni
The response of a linear system to an external perturbation is governed by the Fourier limit, with the inverse of the interaction time constituting a lower limit for the system ban…
Magnetic Phase Diagram of Light-mediated Spin Structuring in Cold Atoms
Guillaume Labeyrie, Ivor Kresic, Gordon R. M. Robb +3
When applying a red-detuned retro-reflected laser beam to a large cloud of cold atoms, we observe the spontaneous formation of 2D structures in the transverse plane corresponding t…
Density matrix approach for quantum free-electron lasers
H. Fares, G. R. M. Robb, N. Piovella
The density matrix in the Lindblad form is used to describe the behavior of the Free-Electron Laser (FEL) operating in a quantum regime. The detrimental effects of the spontaneous…
