PICS Colloquium: Learning to Model the World (and Yourself) from Vision with Vincent Sitzmann

Penn Institute for Computational Science 3401 Walnut Street, 5th Floor, Philadelphia

Abstract: In this talk, I will discuss recent publications from my group that attempt at learning models of the world and the effect of the actions of an agent within that world self-supervised, solely via interaction. In particular, I will discuss the potential and challenges of video generative models as a candidate for such a […]

PICS Colloquium: Multiscale simulations of soft matter: from block copolymers to biomolecular condensates with Josh Lequieu

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia

Abstract: Polymers are ubiquitous in both synthetic and biological materials and underlie technologies as diverse as surfactants, adhesives, proteins and DNA. One of the defining features of all polymeric materials is that they are characterized by a wide range of length scales, often involving phenomena that span nanometers to microns. This hierarchy of length scales […]

PICS Colloquium: A geometric model for superfluid helium-4 with Michal Pavelka

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia

Abstract: Superfluid helium is a peculiar liquid. For instance, it stays liquid even at very low temperatures (below 2K), it flows through narrow capillaries without friction, and temperature gradient makes it move even in the absence of pressure gradient. The usual description of superfluid helium-4 relies on the concept of two fluids, a so called […]
