Inferring the parameters of a Markov process from snapshots of the steady state
Simon Lee Dettmer, Johannes Berg
We seek to infer the parameters of an ergodic Markov process from samples taken independently from the steady state. Our focus is on non-equilibrium processes, where the steady sta…
Network inference in the non-equilibrium steady state
Simon L. Dettmer, H. Chau Nguyen, Johannes Berg
Non-equilibrium systems lack an explicit characterisation of their steady state like the Boltzmann distribution for equilibrium systems. This has drastic consequences for the infer…
Local characterization of hindered Brownian motion by using digital video microscopy and 3D particle tracking
Simon L Dettmer, Ulrich F Keyser, Stefano Pagliara
In this article we present methods for measuring hindered Brownian motion in the confinement of complex 3D geometries using digital video microscopy. Here we discuss essential feat…
Anisotropic diffusion of spherical particles in closely confining microchannels
Simon L Dettmer, Stefano Pagliara, Karolis Misiunas +1
We present here the measurement of the diffusivity of spherical particles closely confined by narrow microchannels. Our experiments yield a two-dimensional map of the position-depe…
Localization and Anomalous Transport in a 1-D Soft Boson Optical Lattice
A. K. Tuchman, W. Li, H. Chien +2
We study the dynamics of Bose-Einstein condensed atoms in a 1-D optical lattice potential in a regime where the collective (Josephson) tunneling energy is comparable with the on-si…
Spectroscopy of Dark Soliton States in Bose-Einstein Condensates
K. Bongs, S. Burger, D. Hellweg +7
Experimental and numerical studies of the velocity field of dark solitons in Bose-Einstein condensates are presented. The formation process after phase imprinting as well as the pr…
