Light, matter, action: Shining light on active matter
Light carries energy and momentum. It can therefore alter the motion of objects on the
atomic to astronomical scales. Being widely available, readily controllable, and broadly …

Chiral active matter
Chiral active matter comprises particles which can self-propel and self-rotate. Examples
range from sperm cells and bacteria near walls to autophoretic L-shaped colloids. In this …

Entropy production of nonreciprocal interactions
Nonreciprocal interactions are present in many systems out of equilibrium. The rate of
entropy production is a measure that quantifies the time irreversibility of a system, and thus …

Network effects lead to self-organization in metabolic cycles of self-repelling catalysts
Mixtures of particles that interact through phoretic effects are known to aggregate if they
belong to species that exhibit attractive self-interactions. We study self-organization in a …

Corneal endothelium assessment in specular microscopy images with Fuchs' dystrophy via deep regression of signed distance maps
Specular microscopy assessment of the human corneal endothelium (CE) in Fuchs'
dystrophy is challenging due to the presence of dark image regions called guttae. This …

Collective behavior of active molecules: Dynamic clusters, holes, and active fractalytes
S Fehlinger, B Liebchen - Physical Review Research, 2023 - APS
Recent experiments have led to active colloidal molecules, which aggregate from nonmotile
building blocks and acquire self-propulsion through their nonreciprocal interactions. Here …

Non-Hermitian non-equipartition theory for trapped particles
The equipartition theorem is an elegant cornerstone theory of thermal and statistical physics.
However, it fails to address some contemporary problems, such as those associated with …

Spontaneous chiral symmetry breaking in a random driven chemical system
Living systems have evolved to efficiently consume available energy sources using an
elaborate circuitry of chemical reactions which, puzzlingly, bear a strict restriction to …

Non-Reciprocal Interactions Reshape Topological Defect Annihilation
We show how non-reciprocal ferromagnetic interactions between neighbouring planar spins
in two dimensions, affect the behaviour of topological defects. Non-reciprocity is introduced …
