Order and shape dependence of mechanical relaxation in proliferating active matter
Jonas Isensee, Lukas Hupe, Philip Bittihn
Collective dynamics in proliferating anisotropic particle systems arise from an interplay between growth, division, and mechanical interactions, often mediated by particle shape. I…
Prediction and control of geometry-induced nematic order in growing multicellular systems
Lukas Hupe, Jonas Isensee, Ramin Golestanian +1
In densely-packed two-dimensional systems of growing cells, such as rod-shaped bacteria, a number of experimental and numerical studies report distinct patterns of nematic orientat…
Phase separation in a mixture of proliferating and motile active matter
Lukas Hupe, Joanna M. Materska, David Zwicker +3
Proliferation and motility are ubiquitous drivers of activity in biological systems. Here, we study a dense binary mixture of motile and proliferating particles with exclusively re…
Isovolumetric dividing active matter
Samantha R. Lish, Lukas Hupe, Ramin Golestanian +1
We introduce and theoretically investigate a minimal particle-based model for a new class of active matter where particles exhibit directional, volume-conserving division in confin…
A minimal model of smoothly dividing disk-shaped cells
Lukas Hupe, Yoav G. Pollack, Jonas Isensee +3
Replication through cell division is one of the most fundamental processes of life and a major driver of dynamics in systems ranging from bacterial colonies to embryogenesis, tissu…
Motility-induced mixing transition in exponentially growing multicellular spheroids
Torben Sunkel, Lukas Hupe, Philip Bittihn
Growth drives cellular dynamics in dense aggregates including bacterial colonies, developing tissues, and tumors. We investigate the underlying physical principles emerging from th…
Stress anisotropy in confined populations of growing rods
Jonas Isensee, Lukas Hupe, Ramin Golestanian +1
Order and alignment are ubiquitous in growing colonies of rod-shaped bacteria due to the nematic properties of the constituent particles. These effects are the result of the active…
Estimating Lyapunov exponents in billiards
George Datseris, Lukas Hupe, Ragnar Fleischmann
Dynamical billiards are paradigmatic examples of chaotic Hamiltonian dynamical systems with widespread applications in physics. We study how well their Lyapunov exponent, character…
