Research Interests

My research group and I focus on statistical mechanics and thermodynamics at the molecular level, with a particular emphasis on far-from-equilibrium phenomena. We have worked on topics that include the application of statistical mechanics to problems of biophysical interest; the analysis of artificial molecular machines; the development of efficient numerical schemes for estimating thermodynamic properties of complex systems; the relationship between thermodynamics and information processing. We also have interests in dynamical systems, quantum thermodynamics, and quantum and classical shortcuts to adiabaticity.

Research

In the Jarzynski group, we develop theoretical tools for understanding nonequilibrium behavior and computational methods for estimating thermodynamic properties, and we construct simple models that provide insight into complex phenomena. We also tackle problems in biophysics, dynamical systems, and quantum dynamics and thermodynamics. The following descriptions provide a flavor of the research that goes on in the group.

Thermodynamics of small systems

While the laws of thermodynamics were developed in the nineteenth century, currently there is exciting progress in understanding how these laws apply to nanoscale systems, especially away from thermal equilibrium. At microscopic length scales, random fluctuations are prevalent, and the energy of interaction between a system and its surroundings cannot be neglected. We investigate how these and other features can be integrated into a broad theoretical framework that describes small system thermodynamics.1,2,3 We work with experimental colleagues to test these results,4 and to apply them in biophysical contexts.5

Thermodynamics of information processing

This topic dates back to the famous “Maxwell’s demon” thought experiment. Recent years have seen renewed theoretical and experimental interest in the thermodynamics of information processing. We study the interplay between information processing and the second law of thermodynamics,6 and we develop models illustrating how a mechanical Maxwell’s demon might operate.7

Shortcuts to adiabaticity: controlling quantum, classical and stochastic systems

The quantum adiabatic theorem provides a powerful tool for controlling the evolution of a quantum system, as long as we act on it very slowly. Shortcuts to adiabaticity are tools that promise the same degree of control, without the requirement of slow driving. We develop novel approaches for constructing shortcuts to adiabaticity, not only in quantum but also in classical and stochastic systems.8
