Temperature chaos in directed polymers
Shirshendu Ganguly, Victor Ginsburg, Zoe Himwich
Disordered systems such as spin glasses and polymers characteristically exhibit random energy landscapes with many macroscopically separated energetic valleys corresponding to near…

Last passage percolation in hierarchical environments
Shirshendu Ganguly, Victor Ginsburg, Kyeongsik Nam
Last passage percolation (LPP) is a model of a directed metric and a zero-temperature polymer where the main observable is a directed path evolving in a random environment accruing…

Pinning, diffusive fluctuations, and Gaussian limits for half-space directed polymer models
Victor Ginsburg
Half-space directed polymers in random environments are models of interface growth in the presence of an attractive hard wall. They arise naturally in the study of wetting and entr…
