Superradiance as single scattering embedded in an effective medium

P. Weiss, A. Cipris, R. Kaiser +2

We present an optical picture of linear-optics superradiance, based on a single scattering event embedded in a dispersive effective medium composed by the other atoms. This linear-…

Subradiance with saturated atoms: population enhancement of the long-lived states

A. Cipris, N. A. Moreira, T. S. do Espirito Santo +5

Dipole-dipole interactions are at the origin of long-lived collective atomic states, often called subradiant, which are explored for their potential use in novel photonic devices o…

Multistability and rare spontaneous transitions in barotropic -plane turbulence

Eric Simonnet, Joran Rolland, Freddy Bouchet

We demonstrate that turbulent zonal jets, analogous to Jovian ones, which are quasi-stationary, are actually metastable. After extremely long times, they randomly switch to new con…

Fluid dynamics of COVID-19 airborne infection suggests urgent data for a scientific design of social distancing

M. E. Rosti, S. Olivieri, M. Cavaiola +2

The COVID-19 pandemic is largely caused by airborne transmission, a phenomenon that rapidly gained the attention of the scientific community. Social distancing is of paramount impo…
