Mean-Field Theory of Chiral Active Model B: Arrested Coarsening and Chiral Fingering Instabilities
Kristian Blom, Uwe Thiele
The paper develops a mean‑field description of a chiral active version of Model B, showing how a rotational bias leads to anisotropic, arrested coarsening and a fingering instabili…
Strong Mpemba Effect Through a Reentrant Phase Transition
Kristian Blom, Doron Benyamin, Uwe Thiele +2
We investigate temperature quenches across the reentrant phase transition of the antiferromagnetic Ising model in a magnetic field and show that the strong direct and inverse Mpemb…
Dynamic Models for Two Nonreciprocally Coupled Fields: A Microscopic Derivation for Zero, One, and Two Conservation Laws
Kristian Blom, Uwe Thiele, Aljaž Godec
We construct dynamic models governing two nonreciprocally coupled fields for several cases with zero, one, and two conservation laws. Starting from two microscopic nonreciprocally…
Local Order Controls the Onset of Oscillations in the Nonreciprocal Ising Model
Kristian Blom, Uwe Thiele, Aljaž Godec
We elucidate the generic bifurcation behavior of local and global order in the nonreciprocal Ising model evolving under Glauber dynamics. We show that a critical magnitude of neare…
