Phase Transitions as the Breakdown of Statistical Indistinguishability
Taiyo Narita, Hideyuki Miyahara
We introduce a novel characterization of phase transitions based on hypothesis testing. In our formulation, a phase transition is defined as the breakdown of statistical indistingu…
Absence of symmetry in the Vicsek model
Yushin Takahashi, Kota Mitsui, Tsuyoshi Mizohata +1
The phase transition in the Vicsek model is widely believed to be associated with spontaneous symmetry breaking of the two-dimensional rotational symmetry . In this…
Vicsek Model Meets DBSCAN: Cluster Phases in the Vicsek Model
Hideyuki Miyahara, Hyu Yoneki, Tsuyoshi Mizohata +1
The Vicsek model, which was originally proposed to explain the dynamics of bird flocking, exhibits a phase transition with respect to the absolute value of the mean velocity. Altho…
Emergent invariance and scaling properties in the collective return dynamics of a stock market
Hideyuki Miyahara, Hai Qian, Pavan Holur +1
Several works have observed heavy-tailed behavior in the distributions of returns in different markets, which are observable indicators of underlying complex dynamics. Such prior w…
Steady-state thermodynamics for population dynamics in fluctuating environments with side information
Hideyuki Miyahara
Steady-state thermodynamics (SST) is a relatively newly emerging subfield of physics, which deals with transitions between steady states. In this paper, we find an SST-like structu…
Many-body perturbation theory and fluctuation relations for interacting population dynamics
Hideyuki Miyahara
Population dynamics deals with the collective phenomena of living organisms, and it has attracted much attention since it is expected to explain how not only living organisms but a…
Work relations with measurement and feedback control on nonuniform temperature systems
Hideyuki Miyahara, Kazuyuki Aihara
The relation between the work performed to a system and the change of its free energy during a certain process is important in nonequilibrium statistical mechanics. In particular,…
