Evolution in range expansions with competition at rough boundaries
Sherry Chu, Mehran Kardar, David R. Nelson +1
When a biological population expands into new territory, genetic drift develops an enormous influence on evolution at the propagating front. In such range expansion processes, fluc…
Optimal paths on the road network as directed polymers
A. P. Solon, G. Bunin, S. Chu +1
We analyze the statistics of the shortest and fastest paths on the road network between randomly sampled end points. To a good approximation, these optimal paths are found to be di…
Probability distributions for directed polymers in random media with correlated noise
Sherry Chu, Mehran Kardar
The probability distribution for the free energy of directed polymers in random media (DPRM) with uncorrelated noise in dimensions satisfies the Tracy-Widom distribution. W…
Reflectionless CMV matrices and scattering theory
Sherry Chu, Benjamin Landon, Jane Panangaden
Reflectionless CMV matrices are studied using scattering theory. By changing a single Verblunsky coefficient a full-line CMV matrix can be decoupled and written as the sum of two h…
