Suppression of noise-induced modulations in multidelay systems

Many physical systems involve time-delayed feedback or coupling. In such delay-systems noise can give rise to undesirable oscillations at frequencies resonant to the delay times. We investigate how an additional feedback term can suppress noise-induced modulations in delay-systems with self-feedback that exhibit deterministic oscillatory dynamics. For the prototypical example of a Stuart-Landau oscillator we derive an equation which describes how the stability of the oscillating solutions depends on the feedback delay times. The stability of the solutions is related to the noise-induced modulations, hence this equation can be used to find feedback conditions for which the noise-induced modulations are reduced. For more complex systems it is sometimes not possible to derive an equivalent analytic expression, however, we show that under certain conditions the dependence on the feedback delays time, of the stability of various oscillatory systems, is ubiquitous.

A real world example for which this work is of relevance is a semiconductor passively mode-locked laser. Such a laser produces a train of light pulses and for applications it is generally desired that the pulses arrive at highly regular time intervals. However, the regularity of the pulse trains is invariably diminished by noise sources within the laser. With one feedback loop the regularity of the pulse trains can be improved on long time scales, however this also introduces a noise-induced modulation of the time between consecutive pulses with a period given approximately by the feedback delay time. By adding a second feedback loop and using the expression we found for the delay time dependence of the stability of the pulsed solutions, the length of the second feedback loop can be chosen such that the noise-induced modulations are suppression, thereby improving the temporal regularity of the pulse train.

Left - The ancient idea of the centrifugal governor (top, from Wikipedia) was transferred to modern electronic nano-devices (bottom). Right - Whereas without control the shot noise (dashed curve) grows indefinitely in time, with control it saturates and reaches a constant value inversely proportional to the feedback strength. Experimental results (dotted lines) and theory (solid lines) correspond perfectly. Note the logarithmic scaling for the plot.

Strong suppression of shot noise in a feedback-controlled single-electron transistor

In ordinary electric devices there are so many electrons flowing through the cable that it suffices to characterize only their average behavior by a single quantity: the electric current. But due to the enormous progress in nanotechnology it is now possible to detect the motion of single electrons in very small devices. At this resolution, however, it does not suffice to characterize the device simply based on its average current; in contrast, the transport of electrons can only be described probabilistically. The dominant contribution to this inherent statistical nature is known as ”shot noise”, which limits our ability to build reliable and easily predictable nanotechnological devices.
We succeeded for the first time to control and almost completely suppress the shot noise due to a real-time feedback loop applied to the system. The basic idea behind this experiment can be traced back to an ancient machine devised by James Watt known as the centrifugal governor. The centrifugal governor controls the speed of a heat engine by self-regulating the amount of fuel supplied with respect to a fixed reference value. Consequently, it is possible to stabilize the motion of the engine independent of the environmental conditions, i.e., the effect of inevitable noise in the fuel supply is suppressed to a minimum. An analogous effect was now predicted and experimentally confirmed in a collaboration of researchers from the GRK and an experimental group from the university of Hannover.

Distribution of active Brownian particles (ABPs) and and run-and-tumble particles (RTPs) in a Matryoshka-like maze in the steady state. ABPs accumulate at the rim, whereas RTP are encountered all through the maze.

Active Brownian particles and run-and-tumble particles separate inside a maze

Microorganisms as well as artificial microswimmers need to navigate through confined environments. Two important models for microswimmers exist: active Brownian particles (ABPs) move with constant speed and continuously change their directions, while for run-and-tumble particles (RTPs) straight runs are interrupted by abrupt changes in direction.
We numerically study how both types of swimmers behave in various two-dimensional mazes. We demonstrate that ABPs can be separated from RTPs by means of geometrical confinement. Especially Matryoshka-like mazes with nested circular shells are efficient filters: ABPs quickly escape the center of the maze and accumulate at the outer rim. In contrast, RTBs can access the inner regions when starting from the fringe of the maze and are more evenly spread across the maze in the steady state. We corroborate this finding using a rate theory. Our results suggest that Matryoshka-like mazes separate different types of active particles from each other, which has potential technological and biomedical applications.

Collisions of deformable cells lead to collective migration

Collective migration of eukaryotic cells plays a fundamental role in tissue growth, wound healing and immune response. We present a model based on reaction-diffusion equations to describe the movement of many self-organized, interacting cells crawling on a layer of substrate. The model accounts for the 'propulsion engine' of each cell in form of acto-myosin dynamics, as well as for adhesion of cells to the substrate and to each other. It predicts that collective cell migration emerges spontaneously as a result of inelastic collisions between neighboring cells: collisions lead to a mutual alignment of the cell velocities and to the formation of coherently-moving multi-cellular clusters. As a result, cells migrate collectively in the same direction in unbounded domains or perform concerted rotation inside a circular domain.
