[Theory-seminars] Seminar tomorrow

[Raza Sufian]

Dear All, 

Here is a reminder for the seminar tomorrow:
> 
> Theory seminar:
> Friday, March 22th, 1:00PM, Room L102
> Kimberley Cushman (Yale University) “Prony Methods for Extracting Excited States”
> 
> Abstract: 
> We hope to improve excited state extraction for our research in beyond the standard model composite Higgs dynamics. We propose an algebraic method of extracting excited states from lattice correlation functions which is also useful to lattice gauge theorists in general, as well as data analysts investigating exponentially decaying signals. Instead of fitting to a linear combination of exponentials, we adopt a variant of Prony’s method to obtain M energies (exponential decay rates) by finding the roots of an Mth order polynomial. I will describe the challenges faced in this approach and demonstrate our attempts to overcome them.
