K. L. Kirkpatrick
Associate Professor of
Mathematics and Physics
A note to prospective students:
I'm not teaching during the academic year 2020-2021, but you may click on any of the courses below.
Research Interests: quantum and statistical mechanics,
condensed matter, and machine learning.
Here's a general
description of some of my results and aims.
Specifically, I'm interested in:
- Working with a student who is fluent in quantum mechanics and German and/or French.
- Quantum groups as models of freely independent random
variables, especially in non-tracial von Neumann algebras.
- Quantum statistical mechanics models:
Bose-Einstein condensation and nonlinear Schrödinger
equations (NLS), discrete NLS and other lattice systems with noise or long-range interactions, and fractional NLS models of energy transport in biopolymers like DNA. Terry
Tao's blog entry about some of my BEC work.
- Classical statistical mechanics: soft-sphere models of plasmas, and the Landau equation in the weak coupling limit.
- Computational probability, algorithms, and family genetic data
models of ferromagnets and superconductors: Heisenberg
model, XY model,
coupled XY models, Toy Higgs model, other O(N) models, and connections with
macroscopic equations for magnets and superconductors, especially
- What's new: Foundations of
computer science, cognitive science, and artificial intelligence.
- Recent paper: Limiting Behaviors of High Dimensional
Stochastic Spin Ensemble, with Gao, Marzuola, Mattingly, and Newhall: arxiv.org/abs/1806.05282
- Recent paper: Transport of a quantum particle in a time-dependent white-noise potential, with Hislop, Olla, and Schenker: arxiv.org/abs/1807.08317
- Here are links to my paper, The
Turing Test Relies on a Mistake about the Brain, my
2018 Beckman talk slides, BIO-LOGIC:
Biological Computation, and IMCT talk slides, Bose-Einstein
Condensation and Biological Machines.
I've mentored Illinois
Geometry Lab projects on percolation
theory with Michelle Delcourt and Thomas Mahoney, and a
project on phase transitions in XY models with Tayyab Nawaz.
My NSF CAREER Award has been providing partial support for Urbana's
Blog: How to
Grad School While Poor.
