Matthew Nicoletti

I am a 5th year PhD student at MIT, advised by Alexei Borodin. Before that, I was an undergraduate at UC Berkeley. I'm interested in probability, combinatorics, and mathematical physics. Currently, I am mainly studying interacting particle systems and exactly solvable lattice models in statistical mechanics.

A few simulations

  • Competitive erosion is a model for an evolving interface between two competing species, see and for background. Here are simulations of the model on the cylinder and in a simply connected pill shaped domain. Here are slides from a short talk at Cornell Probability summer school, based on unpublished calculations with a collaborator, Ananth Sridhar, where we heuristically compute the fluctuations of the interface. (Many thanks to my great friend Daniel Lengyel for help with the numerics and simulations).
  • Lecture Hall Tableaux are combinatorial objects which can be viewed as ensembles of non-intersecting lattice paths on a special lattice. Here is a uniformly random sample (with one particular boundary condition), constructed using "coupling from the past".

  • T-embeddings are special graph embeddings which are compatible with the dimer model Boltzmann measures. Below are pictures of t-embeddings for ``uniform Aztec diamond graphs'' and for ``tower graphs'', with the image of the embedded edges under the associated ``origami maps'' in blue. On the right we show a graph of the origami map for the tower graph.
