Journal Club is a group that meets bi-weekly to listen to and present summaries of exciting and insightful research papers. You can present any paper you’d like, any meeting week you’d like! Check out the start-up notice with more details regarding the club mission and expectations.

This week we'll be having our third Journal Club meeting! Come join us if you're interested in learning about:

1) "Small world" networks and epidemiological modelling

2) Foundations of superresolution quantum imaging

Below are further details for the next meeting:

Title: "Collective dynamics of "small-world" networks (Watts, Strogatz 1998) AND Epidemics on Coevolving Networks"

Abstract: 

This presentation will have two parts. The first part will review an incredibly influential paper in the field of network science by Watts and Strogatz which defines and expands upon the relevance of a topological model for networks that can exist in the regime between completely ordered and completely random. The second part will be a brief research presentation of the presenter's work on developing an epidemiological model for diseases in coevolving networks

Title: "Quantum Theory of Superresolution for Two Incoherent Optical Point Sources"

Abstract: 

Rayleigh’s criterion for resolving two incoherent point sources has been the most influential measure of optical imaging resolution for over a century. In the context of statistical image processing, violation of the criterion is especially detrimental to the estimation of the separation between the sources, and modern far-field superresolution techniques rely on suppressing the emission of close sources to enhance the localization precision. Using quantum optics, quantum metrology, and statistical analysis, here we show that, even if two close incoherent sources emit simultaneously, measurements with linear optics and photon counting can estimate their separation from the far field almost as precisely as conventional methods do for isolated sources, rendering Rayleigh’s criterion irrelevant to the problem. Our results demonstrate that superresolution can be achieved not only for fluorophores but also for stars.
