Fast Radio Bursts (FRBs) emanate from extragalactic sources and are characterized by short (from tens of μs to several ms) and powerful bursts of radiation detected at radio frequencies with bandwidths often spanning several hundreds of MHz. But despite increasing observational efforts aimed at their detection and the characterization of their host environments, the nature of FRBs remains elusive. In this presentation I will discuss the application of Dicke’s superradiance (SR) to the FRB problem while endeavouring to account for the significant amount of data obtained on FRB 121102, the only such source that has so far been precisely located and had its host identified. Although it has remained unnoticed by the astrophysics community until very recently, SR has been a very active field of research in the quantum optics community since its introduction by R. H. Dicke in 1954. In this presentation, I will start by giving a brief description of the physics underlying Dicke’s SR and show how this quantum mechanical entanglement phenomenon could help in elucidating the nature of FRBs. In particular, I will show how a young pulsar located at ∼100 pc or more from an SR/FRB system could initiate the onset of a powerful burst of radiation detectable over cosmological distances.
The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
