Turbulent Liquid Crystals, KPZ Universality and the Asymmetric Simple Exclusion Process
Student-Run Research Seminar| Speaker: | Craig Tracy, UC Davis |
| Location: | 2112 MSB |

We report on (1) recent experimental work on stochastically growing interfaces and (2) new theoretical developments for the KPZ equation, a stochastic nonlinear PDE, and the closely related asymmetric simple exclusion process.
