Recent highlights

Unexpected extension in The Journal of Physical Chemistry B, 2023
Conceived as an extension of our previous study [JPCL 2021] to unveil the nature of the limit cycle, we have unpexpectedly arrived at a novel two-variable model of a pH oscillator, which is virtually exact reduction from four variables. Read more

Curious story in The Journal of Physical Chemistry Letters, 2021
published within less than 4 weeks
Rhythms are vital for a variety of processes of life with the pH level having a strong impact on cell performance. Their machinery is hidden in small reaction compartments such as vesicles. How does their smallness affect the rhythm? Read more

Experiment & theory story in Nature Communications, 2021 [ZIB News]
Being of great technological potential, assembling nanosized magnetic particles on surfaces presents a formidable challenge. Using theory to rationalize the experiment, we overcome this problem for traps created by magnetic domain walls. Read more

On the cover for October & Editor's highlight in Communications Physics, 2020
How friction in liquids emerges from conservative forces between atoms is currently not well understood. We combine frequency-resolved simulation data with theory to show that the friction felt by a single molecule occurs abruptly below a certain frequency.

Experiment & theory story in Physical Review Letters, 2020
Directional locking is observed when a colloidal monolayer is driven across and interacts with a triangular lattice of magnetic bubbles. While single particles show no preferred direction, collective effects induce transversal current and directional locking at high density via a spontaneous symmetry breaking.

Details: Phys. Rev. Lett. 124, 058002 (2020)
Rapid Communication & Editor's suggestion in Physical Review Research, 2019 We suggest a theoretical framework to understand how colloidal swimmers propel, interact and assemble in a nematic liquid crystal media by an alternating current electric field. Our results demonstrate importance of hydrodynamic interactions on the assembly of driven microscale matter in anisotropic media.
