Prof. Mihail Petrov delivered a seminar at the University of Brescia on Monday 26 February 2024 entitled « Subradiant collective states in ordered arrays of quantum emitters ».

Abstract. Subradiance is one of the optical effects that plays a key role in modern quantum optics, laser physics, and nanophotonics. In the talk, we will discuss appearance of subradiant states in arrays of dipole quantum emitters ordered in lattices and oligomer-type structures. We will see how the formation of long-living quantum states is influenced by the band structure of the arrays and controlled by the flat-band effects, and by the geometry of the quantum ensembles. Also, we will present some experimental proof-of-principal results done in the microwave range.
