Towards AC-induced optimum control of dynamical localization

F. Revuelta, R. Chacón, F. Borondo

It is shown that optimum control of dynamical localization (quantum suppression of classical diffusion) in the context of ultracold atoms in periodically shaken optical lattices su…

Maximum population transfer in a periodically driven two-level system

P. M. Poggi, F. J. Arranz, R. M. Benito +2

We study the dynamics of a two-level quantum system under the influence of sinusoidal driving in the intermediate frequency regime. Analyzing the Floquet quasienergy spectrum, we f…

The colored Hanbury Brown--Twiss effect

Blanca Silva, C. Sánchez Muñoz, D. Ballarini +8

The Hanbury Brown--Twiss effect is one of the celebrated phenomenologies of modern physics that accommodates equally well classical (interferences of waves) and quantum (correlatio…

Generation, manipulation, and detection of two-qubit entanglement in waveguide QED

C. Gonzalez-Ballestero, Esteban Moreno, F. J. Garcia-Vidal

We study the possibility of using guided photons to generate, control, and measure the entanglement of two qubits that is mediated by a one-dimensional waveguide. We show how entan…

Violation of classical inequalities by photon frequency-filtering

Carlos Sánchez Muñoz, Elena del Valle, Carlos Tejedor +1

The violation of the Cauchy-Schwarz and Bell inequalities ranks among the major evidences of the genuinely quantum nature of an emitter. We show that by dispensing from the usual a…

Spontaneous, collective coherence in driven, dissipative cavity arrays

J. Ruiz-Rivas, E. del Valle, C. Gies +2

We study an array of dissipative tunnel-coupled cavities, each interacting with an incoherently pumped two-level emitter. For cavities in the lasing regime, we find correlations be…
