Reaction Delays Boost, Rectify, and Reverse Motility in Activity Landscapes
Constantin Rein, Klaus Kroy, Viktor Holubec
Local detailed balance restricts transport by self-propulsion in static activity landscapes. We show that a delayed speed adaptation (``delayed motility/kinesis'') generically brea…
Probing scale-dependent liveliness with nonequilibrium thermospectroscopy
Joscha Mecke, Klaus Kroy
Probing the spatially heterogeneous activity across scales is a major challenge in living matter. Energy injection at diverse length scales leads to mode coupling, inter-modal ener…
Coevolving aerodynamic and impact ripples on Earth
Hezi Yizhaq, Katharina Tholen, Lior Saban +11
Windblown sand creates multiscale bedforms on Earth, Mars, and other planetary bodies. According to conventional wisdom, decameter-scale dunes and decimeter-scale ripples emerge vi…
Active Ornstein-Uhlenbeck Model for Bacterial Heat Engines
Roland Wiese, Klaus Kroy, Viktor Holubec
We use Brownian dynamics simulations to study a model of a cyclic bacterial heat engine based on a harmonically confined colloidal probe particle in a bath formed by active Brownia…
Modeling the Efficiency and Effective Temperature of Bacterial Heat Engines
Roland Wiese, Klaus Kroy, Viktor Holubec
We present a Brownian dynamics simulation of the bacterial Stirling engine studied by Krishnamurthy et al., Nat. Phys. 12, 1134 (2016). In their experimental setup, an overdamped c…
Time-reversal and PT symmetry breaking in non-Hermitian field theories
Thomas Suchanek, Klaus Kroy, Sarah A. M. Loos
We study time-reversal symmetry breaking in non-Hermitian fluctuating field theories with conserved dynamics, comprising the mesoscopic descriptions of a wide range of nonequilibri…
