We discuss how contact with a nonequilibrium bath can modify the effective dynamics of a probe. In particular, systematic forces may become nongradient; the second fluctuation-dissipation relation can be broken and the noise may be nonGaussian and showing power law distributed jumps.

Tracking individual proteins on the surface of live mammalian cells reveals complex dynamics involving anomalous diffusion and clustering into nanoscale domains. Theoretical models show that anomalous subdiffusion can be caused by different processes. Here we study the nonergodic dynamics of voltage gated ion channels in human embryonic kidney (HEK) cells and in hippocampal neurons. We perform...

Molecular motors are responsible for numerous cellular processes from cargo transport to heart contraction. Their interactions with other cellular components are often transient and exhibit kinetics that depend on load. Here, we measure such interactions using a new method, “Harmonic Force Spectroscopy.” In this method, harmonic oscillation of the sample stage of a laser trap immediately,...

We study the dynamics of Brownian particles in a heterogeneous one-dimensional medium with a spatially-dependent diffusion coefficient of the form $D(x)\sim|x|^c$, at constant temperature. The particle’s probability distribution function (PDF) is calculated both analytically, by solving Fick’s diffusion equation, and from numerical simulations of the underdamped Langevin equation. At large...

The Kardar-Parisi-Zhang (KPZ) equation describes an important universality class of nonequilibrium stochastic growth. There has been much recent interest in the one-point probability distribution P(H,t) of height H of the evolving interface at time t. I will show how one can use the optimal fluctuation method (also known as the instanton method, the weak-noise theory, the macroscopic...

In patients with end-stage heart disease the heart transplantation (HTx) is associated with significant improvement in survival and in quality of life. However strong immunosuppressive drugs together with processes of aging could lead to vasculopathy and fibrosis of the donor heart. Moreover a spontaneous process of reinnervation proceeds in the myocardial tissue. All together impact on...
