Adding noise and scaling forces to speed up the Langevin clock
Prithviraj Basak, Stephen Whitelam, John Bechhoefer
Using experiments on a colloidal particle trapped in an optical tweezer, we confirm a recent proposal to increase the effective mobility or clock rate of systems described by Lange…

Improving noisy free-energy measurements by adding more noise
Stephen Whitelam
Estimating free-energy differences using nonequilibrium work relations, such as the Jarzynski equality, is hindered by poor convergence when work fluctuations are large. For system…

Competing addition processes give distinct growth regimes in the assembly of 1D filaments
Sk Ashif Akram, Tyler Brown, Stephen Whitelam +3
We present a model to describe the concentration-dependent growth of protein filaments. Our model contains two states, a low entropy/high affinity ordered state and a high entropy/…
