What do thermodynamic dissipation, electrical resistance, random-walk commute times, and optimal transport have in common? They describe the same geometry on Markov networks! Beautiful work by Jordan Sawchuk, a Letter and Editors' Suggestion @PhysRevE: doi.org/10.1103/bhr1-lplt

Thermodynamic geometry of friction on graphs: Resistance, commute times, and optimal transport

Geometric ideas play a role in areas such as stochastic thermodynamics, spectral graph theory, and optimal transport. In this Letter, the authors link a thermodynamic friction metric that governs...

Out in @PhysRevLett: @SFUPhysics postdoc Antonio Patrón Castro (in tight collaboration with my colleague John Bechhoefer) pushes our information engine to higher dimensions! doi.org/10.1103/xwjd-qxfg

Harnessing Higher-Dimensional Fluctuations in an Information Engine

We study the optimal performance of an information engine consisting of an overdamped Brownian bead confined in a controllable, $d$-dimensional harmonic trap and additionally subjected to gravity....

He elegantly shows how to convert horizontal thermal jiggles (‘fluctuations’) into vertically raising a weight against gravity. Remarkably, the horizontal fluctuations are more valuable than the vertical ones! (image credit: Jasper Zhang)

Out in @PhysRevResearch: beautiful and fundamental theory from @SFUPhysics PhD student Jordan Sawchuk doi.org/10.1103/j59j-q88v We formulated a global thermodynamic manifold whose metric tensor quantifies the dissipation for complete dynamic control of a system’s energy landscape.

Global thermodynamic manifold for conservative control of stochastic systems

Optimal control of stochastic systems plays a central role in nonequilibrium physics, with applications in the study of biological molecular motors and the design of single-molecule experiments....

Any partial control (say through a few control parameters) is easily derived as a submanifold of this global manifold. Through this we can tractably compare hundreds of different control sets to identify sparse methods for efficient control.
