Cell-induced wrinkling patterns on soft substrates
Aleksandra Ardaševa, Varun Venkatesh, Daiki Matsunaga +2
Cells exert traction forces on compliant substrates and can induce surface instabilities that appear as characteristic wrinkling patterns. Here, we develop a mechanical description…
Non-equilibrium geometric forces steer spiral waves on folded surfaces
Varun Venkatesh, Farzan Vafa, Martin Cramer Pedersen +1
Spiral waves are ubiquitous signatures of non equilibrium dynamics, appearing across chemical, biological, and active systems. Yet, in many living systems these waves unfold on cur…
The Interplay of Polar and Nematic Order in Active Matter: Implications for Non-Equilibrium Physics and Biology
Varun Venkatesh, Niels de Graaf Sousa, Amin Doostmohammadi
Active matter has played a pivotal role in advancing our understanding of non-equilibrium systems, leading to a fundamental shift in the study of biophysical phenomena. The foundat…
Nematic ordering in active fluids driven by substrate deformations: Mechanisms and patterning regimes
Varun Venkatesh, Amin Doostmohammadi
The interplay between active matter and its environment is central to understanding emergent behavior in biological and synthetic systems. Here, we show that coupling active nemati…
