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…
Activity-induced ferromagnetism in one-dimensional quantum many-body systems
Kazuaki Takasan, Kyosuke Adachi, Kyogo Kawaguchi
We study a non-Hermitian quantum many-body model in one dimension analogous to the Vicsek model or active spin models, and investigate its quantum phase transitions. The model cons…
