Condensation of vanishing photon emission rates in random atomic clouds
Viviana Viggiano, Romain Bachelard, Fabio Deelan Cunden +5
In the collective photon emission from atomic clouds both the atomic transition frequency and the decay rate are modified compared to a single isolated atom, leading to the effects…

Optimal control of a quantum sensor: A fast algorithm based on an analytic solution
S. Hernández-Gómez, F. Balducci, G. Fasiolo +3
Quantum sensors can show unprecedented sensitivities, provided they are controlled in a very specific, optimal way. Here, we consider a spin sensor of time-varying fields in the pr…
