Ultrafast laser irradiation can trigger anisotropically structured nanoscaled gratinglike
arrangements of matter, the laser-induced periodic surface structures (LIPSSs). We …

Studying femtosecond laser ablation of wide band gap insulators, with BaF2 as a
representative, we observe a complex structure of fine ripples at the bottom of the ablated …

We develop a coupled hydro-morphodynamic numerical model for carrying out large-eddy
simulation of stratified, turbulent flow over a mobile sand bed. The method is based on the …

Complex emergent systems of many interacting components, including complex biological
systems, have the potential to perform quantifiable functions. Accordingly, we define …

Crater morphology is investigated after femtosecond laser ablation of wide bandgap
insulators (BaF2 and CaF2). Experiments performed at a weak laser ablation rate show a …

The understanding of the morphodynamics of harmonic bed forms on the seabed is
essential for modeling marine sediment transport and coastal morphologic development …

One of the most enigmatic steps in Earth's ancient transition from a lifeless planet to a living
world was the process or processes by which prebiotic organic molecules were selected …

Laboratory studies of ripples and dunes show robust relations between bedform geometry
and both fluid flow conditions and grain size. These empirical relations are derived at …

Three principles guide natural pattern formation in both biological and non-living systems:(1)
patterns form from interactions of numerous individual particles, or “agents,” such as sand …

We report the existence of anomalous metamagnetic fluctuations in the vicinity of the
dynamic phase transition (DPT) that do not occur for the corresponding thermodynamic …
