Mean-Field Theory of Chiral Active Model B: Arrested Coarsening and Chiral Fingering Instabilities
Kristian Blom, Uwe Thiele
We derive and analyze a mean-field theory of the chiral Ising model recently introduced by Wang, Pietzonka, and Jülicher in "Edge Currents Shape Condensates in Chiral Active Matter…
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 it provides a natural mechanism for…
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…
Milestoning estimators of dissipation in systems observed at a coarse resolution: When ignorance is truly bliss
Kristian Blom, Kevin Song, Etienne Vouga +2
Many non-equilibrium, active processes are observed at a coarse-grained level, where different microscopic configurations are projected onto the same observable state. Such "lumped…
Global Speed Limit for Finite-Time Dynamical Phase Transition and Nonequilibrium Relaxation
Kristian Blom, Aljaž Godec
Recent works unraveled an intriguing finite-time dynamical phase transition in the thermal relaxation of the mean field Curie-Weiss model. The phase transition reflects a sudden sw…
Thermodynamically Consistent Phase-Field Theory Including Nearest-Neighbor Pair Correlations Explains Failure of Mean-Field Reasoning
Kristian Blom, Noah Ziethen, David Zwicker +1
Most of our current understanding of phase separation is based on ideas that disregard correlaions. Here we illuminate unexpected effects of correlations on the structure and therm…
Criticality in Cell Adhesion
Kristian Blom, Aljaž Godec
We illuminate the many-body effects underlying the structure, formation, and dissolution of cellular adhesion domains in the presence and absence of forces. We consider mixed Glaub…
