The fascinating patterns of collective motion created by autonomously driven particles have
fuelled active-matter research for over two decades. So far, theoretical active-matter …

This work reviews the present position of and surveys future perspectives in the physics of
chaotic advection: the field that emerged three decades ago at the intersection of fluid …

To probe the difference between static-driven and dynamically triggered rockbursts, three
types (static-driven rockburst, SDR; pulse-disturbance rockburst, PUDR; period-disturbance …

In addition to the striking beauty inherent in their complex nature, fractals have become a
fundamental ingredient of nonlinear dynamics and chaos theory since they were defined in …

Mixing is the operation by which a system evolves under stirring from one state of simplicity—
the initial segregation of the constituents—to another state of simplicity—their complete …

Chaotic Dynamics provides a clear introduction to chaotic phenomena, based on
geometrical interpretations and simple arguments, without requiring prior in-depth scientific …

We propose a new experimental set up to characterize mixing and reactive transport in
porous media with a high spatial resolution at the pore scale. The analogous porous …

Natural soils are host to a high density and diversity of microorganisms, and even deep-
earth porous rocks provide a habitat for active microbial communities. In these …

There are numerous physical situations in which a hole or leak is introduced in an otherwise
closed chaotic system. The leak can have a natural origin, it can mimic measurement …

The macroscopic properties of fluid flow and transport through porous media are a direct
consequence of the underlying pore structure. However, precise relations that characterize …
