Automated label flows for excited states of correlation functions in lattice gauge theory
Kimmy K. Cushman, George T. Fleming
Extracting excited states from lattice gauge theory correlation functions can be achieved through chi-squared minimization fits or algebraic approaches such as the variational meth…

Prony methods for extracting excited states
Kimmy K. Cushman, George T. Fleming
We propose an algebraic method for extracting excited states from lattice gauge theory correlation functions. Instead of fitting to a sum of decaying exponentials, we adopt a varia…
