Autor: Yuting I. Li, Günther Turk, Paul B. Rohrbach, Patrick Pietzonka, Julian Kappler, Rajesh Singh, Jakub Dolezal, Timothy Ekeh, Lukas Kikuchi, Joseph D. Peterson, Austen Bolitho, Hideki Kobayashi, Michael E. Cates, R. Adhikari, Robert L. Jack
Publikováno v: Royal Society Open Science, Vol 8, Iss 8 (2021)
Epidemiological forecasts are beset by uncertainties about the underlying epidemiological processes, and the surveillance process through which data are acquired. We present a Bayesian inference methodology that quantifies these uncertainties, for ep

Experimental Measurement of Relative Path Probabilities and Stochastic Actions
Autor: Jannes Gladrow, Ulrich F. Keyser, R. Adhikari, Julian Kappler
Publikováno v: Physical Review X, Vol 11, Iss 3, p 031022 (2021)
For diffusive stochastic dynamics, the probability to observe any individual trajectory is vanishingly small, making it unclear how to experimentally validate theoretical results for ratios of path probabilities. We provide the missing link between t

Stochastic action for tubes: Connecting path probabilities to measurement
Autor: Julian Kappler, Ronojoy Adhikari
Publikováno v: Physical Review Research, Vol 2, Iss 2, p 023407 (2020)
The trajectories of diffusion processes are continuous but nondifferentiable, and each occurs with vanishing probability. This introduces a gap between theory, where path probabilities are used in many contexts, and experiment, where only events with

Barrier-crossing times for different non-Markovian friction in well and barrier: A numerical study
Autor: Florian N. Brünig, Roland R. Netz, Julian Kappler
Publikováno v: Physical Review E. 106
We introduce a generalized Langevin model system for different non-Markovian effects in the well and barrier regions of a potential, and use it to numerically study the dependence of the barrier-crossing time. In the appropriate limits, our model int

Measurement of irreversibility and entropy production via the tubular ensemble
Autor: Julian Kappler, Ronojoy Adhikari
Publikováno v: Physical Review E. 105
The appealing theoretical measure of irreversibility in a stochastic process, as the ratio of the probabilities of a trajectory and its time reversal, cannot be accessed directly in experiment since the probability of a single trajectory is zero. We

Linear waves at viscoelastic interfaces between viscoelastic media
Autor: Sina Zendehroud, Roland R. Netz, Julian Kappler
We derive the general dispersion relation for interfacial waves along a planar viscoelastic boundary that separates two viscoelastic bulk media, including the effect of gravity. Our unified theory contains Rayleigh waves, capillary-gravity-flexural w
