Postdoctoral position: Experimental Probes of Thermodynamic Computing

Postdoctoral Scholar position at the California Institute of Technology, Pasadena.

Available for Physics PhD interested to develop experiments on Engines of Adaptation: Self-Programming via Emergent Thermodynamic Machines in Prof. Michael Roukes’ laboratory, with co-Investigators Prof. Jim Crutchfield (Physics, UC Davis) and Prof. Erik Winfree (Computer Science, Caltech).

The position is available to recent PhDs to carry out original experimental and theoretical research in the fundamental physics of thermodynamic computing--information and computation in nanoscale classical and quantum physical substrates. Key background areas include design and fabrication nanoscale devices for unconventional, ultra-low power information processing. The primary task is the experimental exploration of the fundamental physics of information and computation in classical and quantum phenomena. Familiarity with nonlinear dynamics, pattern formation, and stochastic thermodynamics an asset. Ability to develop and maintain open-source software packages (Python) required.
