Beyond local detailed balance: Microscopic rates reshape nonequilibrium phase behavior
Takahiro Kanazawa, Kyogo Kawaguchi, Kyosuke Adachi
Local detailed balance (LDB) is a central guiding principle for modeling nonequilibrium stochastic dynamics, yet it only constrains the ratio of forward and backward transition rat…
Mean-Field Convective Phase Separation under Thermal Gradients
Meander Van den Brande, François Huveneers, Kyosuke Adachi
Nonequilibrium conditions fundamentally change how systems undergo phase separation. In lattice gases with attractive interactions under temperature gradients, particles have been…
Convection Patterns in Nonequilibrium Kawasaki Dynamics at Low Temperature
Meander Van den Brande, Kyosuke Adachi, Francois Huveneers
We study a conservative stochastic lattice gas (Kawasaki dynamics) coupled in the bulk to a heat bath, which leads to standard phase separation at low uniform temperatures. Instead…
Dynamical phase transitions in single particle Brownian motion without drift
Takahiro Kanazawa, Kyogo Kawaguchi, Kyosuke Adachi
Dynamical phase transitions (DPTs) arise from qualitative changes in the long-time behavior of stochastic trajectories, often observed in systems with kinetic constraints or driven…
Universality in the dynamical phase transitions of Brownian motion
Takahiro Kanazawa, Kyogo Kawaguchi, Kyosuke Adachi
We study the dynamical phase transitions (DPTs) appearing for a single Brownian particle without drift. We first explore how first-order DPTs in large deviations can be found even…
Power-law correlation in the homogeneous disordered state of anisotropically self-propelled systems
Kyosuke Adachi, Hiroyoshi Nakano
Self-propelled particles display unique collective phenomena, due to the intrinsic coupling of density and polarity. For instance, the giant number fluctuation appears in the orien…
Universal properties of repulsive self-propelled particles and attractive driven particles
Hiroyoshi Nakano, Kyosuke Adachi
Motility-induced phase separation (MIPS) is a nonequilibrium phase separation that has a different origin from equilibrium phase separation induced by attractive interactions. Simi…
Universality of active and passive phase separation in a lattice model
Kyosuke Adachi, Kyogo Kawaguchi
The motility-induced phase separation (MIPS) is the spontaneous aggregation of active particles, while equilibrium phase separation (EPS) is thermodynamically driven by attractive…
Activity-induced phase transition in a quantum many-body system
Kyosuke Adachi, Kazuaki Takasan, Kyogo Kawaguchi
A crowd of nonequilibrium entities can show phase transition behaviors that are prohibited in conventional equilibrium setups. An interesting question is whether similar activity-d…
