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…
Harnessing non-equilibrium forces to optimize work extraction
Kristian Stølevik Olsen, Rémi Goerlich, Yael Roichman +1
While optimal control theory offers effective strategies for minimizing energetic costs in noisy microscopic systems over finite durations, a significant opportunity lies in exploi…
Thermodynamic Cost of Recurrent Erasure
Deepak Gupta, Kristian Stølevik Olsen, Supriya Krishnamurthy
Recent experiments have implemented resetting by means of a time-varying external harmonic trap whereby the trap stiffness is changed from an initial to a final value in finite-tim…
Shear-Driven Diffusion with Stochastic Resetting
Iman Abdoli, Kristian Stølevik Olsen, Hartmut Löwen
External flows, such as shear flow, add directional biases to particle motion, introducing anisotropic behavior into the system. Here, we explore the non-equilibrium dynamics that…
Dynamics of switching processes: general results and applications to intermittent active motion
Ion Santra, Kristian Stølevik Olsen, Deepak Gupta
Systems switching between different dynamical phases is an ubiquitous phenomenon. The general understanding of such a process is limited. To this end, we present a general expressi…
Anisotropic Brownian particles under resetting
Subhasish Chaki, Kristian Stølevik Olsen, Hartmut Löwen
We study analytically the dynamics of an anisotropic particle subjected to different stochastic resetting schemes in two dimensions. The Brownian motion of shape-asymmetric particl…
Partial stochastic resetting with refractory periods
Kristian Stølevik Olsen, Hartmut Löwen
The effect of refractory periods in partial resetting processes is studied. Under Poissonian partial resets, a state variable jumps to a value closer to the origin by a fixed fract…
Optimal diffusion of chiral active particles with strategic reorientations
Kristian Stølevik Olsen, Hartmut Löwen
We investigate the competing effects of simultaneous presence of chirality and generalised tumbles in the dynamics of an active Brownian particle. Chiral active particles perform c…
Dynamics of inertial particles under velocity resetting
Kristian Stølevik Olsen, Hartmut Löwen
We investigate stochastic resetting in coupled systems involving two degrees of freedom, where only one variable is reset. The resetting variable, which we think of as hidden, indi…
Thermodynamic work of partial resetting
Kristian Stølevik Olsen, Deepak Gupta
Partial resetting, whereby a state variable is reset at random times to a value , , generalizes conventional resetting by introducing the resetting…
Steady-state moments under resetting to a distribution
Kristian Stølevik Olsen
The non-equilibrium steady states emerging from stochastic resetting to a distribution is studied. We show that for a range of processes, the steady-state moments can be expressed…
Thermodynamic cost of finite-time stochastic resetting
Kristian Stølevik Olsen, Deepak Gupta, Francesco Mori +1
Recent experiments have implemented resetting by means of an external trap, whereby a system relaxes to the minimum of the trap and is reset in a finite time. In this work, we set…
Entropy production of resetting processes
Francesco Mori, Kristian Stølevik Olsen, Supriya Krishnamurthy
Stochastic systems that undergo random restarts to their initial state have been widely investigated in recent years, both theoretically and in experiments. Oftentimes, however, re…
Trapping of active Brownian and run-and-tumble particles: a first-passage time approach
Emily Qing Zang Moen, Kristian Stølevik Olsen, Jonas Rønning +1
We use a first-passage time approach to study the statistics of the trapping times induced by persistent motion of active particles colliding with flat boundaries. The angular firs…
Collective states of active matter with stochastic reversals: emergent chiral states and spontaneous current switching
Kristian Stølevik Olsen, Luiza Angheluta, Eirik Grude Flekkøy
We study collective dynamical behavior of active particles with topological interactions and directional reversals. Surprising phenomena are shown to emerge as the interaction rela…
Diffusion of active particles with angular velocity reversal
Kristian Stølevik Olsen
Biological and synthetic microswimmers display a wide range of swimming trajectories depending on driving forces and torques. In this paper we consider a simple overdamped model of…
The escape problem for active particles confined to a disc
Kristian Stølevik Olsen, Luiza Angheluta, Eirik Grude Flekkøy
We study the escape problem for interacting, self-propelled particles confined to a disc, where particles can exit through one open slot on the circumference. Within a minimal 2D V…
