An active Lorentz gas: walking droplets in periodic media

Aleksi Majaniemi, Esko Toivonen, Rahil N. Valani +2

The Lorentz gas is a paradigmatic model in dynamical systems theory for understanding the origin of nonequilibrium transport in terms of microscopic deterministic chaos. In the per…

An analogue of Kida's formula for Mazur-Tate elements

Naman Pratap, Anwesh Ray

We prove an analogue of Kida's formula for the Iwasawa invariants of the Mazur-Tate elements attached to elliptic curves over . Let be an odd prime and let be…

Neural non-canonical Hamiltonian dynamics for long-time simulations

Clémentine Courtès, Emmanuel Franck, Michael Kraus +2

This work focuses on learning non-canonical Hamiltonian dynamics from data, where long-term predictions require the preservation of structure both in the learned model and in numer…

Diffusion in the Inverted Triangular Soft Lorentz Gas

Esko Toivonen, Aleksi Majaniemi, Rainer Klages +1

We investigate diffusion in a two-dimensional inverted soft Lorentz gas, where attractive Fermi-type potential wells are arranged in a triangular lattice. This configuration contra…

A new look into the atmospheric composition of WASP-39 b

Sushuang Ma, Arianna Saba, Ahmed Faris Al-Refaie +4

Being one of the first exoplanets observed by the James Webb Space Telescope, WASP-39 b has become an iconic target and many transit spectra recorded with different instruments (NI…

Individual particle persistence antagonizes global ordering in populations of nematically-aligning self-propelled particles

Josué Manik Nava-Sedeño, Rainer Klages, Haralampos Hatzikirou +1

The transition from individual to collective motion plays a significant role in many biological processes. While the implications of different types of particle-particle interactio…
