Title: (Non-)stochastic thermodynamics for computing devices 

Abstract:

In this talk I describe several theoretical bounds and illustrate them on how they can place trade-offs on the performance (in terms of dissipation, reliability and speed) of electronic devices and circuits made from them.  These results are consistent with numerical simulations and experimental measurements.  

These results will include, depending on time and interest: 

-tight stochastic and deterministic Thermo-Kinetic Relations (including Speed Limits and Uncertainty Principles), quantifying for instance the amount of dissipation needed to write a bit in a memory; 

-bounds on the skewness (third moment) of fluctuations, implying for instance that ‘very noisy’ devices must be exhibit non-Gaussian fluctuations; 

-nonlinear response theory results, with implication on the reliability of bang-bang bit-writing. 

I will also discuss open questions and possible extensions.
