A particle-resolved rheological study of chirality transfer and odd transport
Rémi Goerlich, Alexander P. Antonov, Kristian Stølevik Olsen +4
Chirality, or the breaking of mirror symmetry, appears across all scales in nature, from molecular conformations to the dynamics of bacterial collectives. Environments composed of…
Self-propulsion protocols for swift non-equilibrium state transitions and enhanced cooling in active systems
Kristian Stølevik Olsen, Hartmut Löwen
A control framework is proposed for inducing non-equilibrium state transitions in confined active matter, where the statistics of self-propulsion serve as the only control paramete…
Information-fluctuation inequalities for collective response
Kristian Stølevik Olsen
Hidden stochastic effects acting uniformly on a many-particle system can generate strong correlations and macroscopic relative fluctuations that persist at large system sizes, even…
Information bound on navigation speed in smart active matter
Kristian Stølevik Olsen, Mitsusuke Tarama, Hartmut Löwen
Intelligent behavior in life-like systems often arises from the ability to gather, process, and act on information. While active matter provides a framework for studying life-like…
Optimal area exploration by resetting active particles
Kristian Stølevik Olsen, Hartmut Löwen, Lorenzo Caprini
Identifying optimal strategies for efficient spatial exploration is crucial, both for animals seeking food and for robotic search processes, where maximizing the covered area is a…
Time-energy tradeoff in stochastic resetting using optimal control
Rémi Goerlich, Kristian Stølevik Olsen, Hartmut Löwen +1
Stochastic resetting is a driving mechanism that is known to minimize the first passage time to reach a target, at the cost of energy expenditure. The choice of the physical implem…
