**Title: ***
Faces of entropy: Connecting Physics, Biology and Quantum Information Science
*

**Abstract: **

Conceptually, entropy is often thought of as a measure of randomness in a
system. But it comes in different flavors depending on the type of a “network”
this concept is applied to. This talk will focus on connections between
thermodynamic, information theory and graph theoretic definitions of entropy
and survey recent theoretical and applied developments. In particular, we
will talk about: (1) the role of microstructure entropy in describing
coarsening processes in materials and quantifying their mechanical
performance, (2) relative entropy of biological networks and protein
sequences, and (3) applications to quantum information science.

**Time:** Friday, March 6, 2020, 3:30-4:20 p.m.

**Place:** Exploratory Hall, room 4106

**Refreshments** will be served at 3:00 p.m.
