Complexity During Inflation

Current ideas in string theory suggest that a fundamental description of inflation may not be simple. The low-energy effective theory relevant for inflation can consist of many degrees of freedom interacting via a highly complex potential, thereby presenting a number of challenges both for model building and for comparison with observation. However, there are good reasons to think these challenges can be overcome. Many complex systems in physics exhibit some form of emergent simplicity. If the same is true for inflation, then a new approach based on stochastic methods may be a powerful way to make progress. In this talk I will present some of the challenges involved in making steps in this direction, as well as some possible ways forwards.
