Anomalous fluctuations of renewal-reward processes with heavy-tailed distributions
Hiroshi Horii, Raphael Lefevere, Masato Itami +1
For renewal-reward processes with a power-law decaying waiting time distribution, anomalously large probabilities are assigned to atypical values of the asymptotic processes. Previ…
Large-time asymptotic of heavy tailed renewal processes
Hiroshi Horii, Raphael Lefevere, Takahiro Nemoto
We study the large-time asymptotic of renewal-reward processes with a heavy-tailed waiting time distribution. It is known that the heavy tail of the distribution produces an extrem…
Do extreme events trigger turbulence decay? - a numerical study of turbulence decay time in pipe flows
Takahiro Nemoto, Alexandros Alexakis
Turbulence locally created in laminar pipe flows shows sudden decay or splitting after a stochastic waiting time. In laboratory experiments, the mean waiting time was observed to i…
Colloidal transport in bacteria suspensions: from bacteria scattering to anomalous and enhanced diffusion
Antoine Lagarde, Noémie Dagès, Takahiro Nemoto +3
Colloids coupled to a bath of swimming cells generically display enhanced diffusion. This transport dynamics stems from a subtle interplay between the active and passive particles…
Dynamical phase coexistence in the Fredrickson-Andersen model
Robert L. Jack, Takahiro Nemoto, Vivien Lecomte
We analyse a first-order dynamical phase transition that takes place in the Fredrickson--Andersen (FA) model. We construct a two-dimensional spin system whose thermodynamic propert…
Dissipation controls transport and phase transitions in active fluids: Mobility, diffusion and biased ensembles
Étienne Fodor, Takahiro Nemoto, Suriyanarayanan Vaikuntanathan
Active fluids operate by constantly dissipating energy at the particle level to perform a directed motion, yielding dynamics and phases without any equilibrium equivalent. The emer…
Imitating non-equilibrium steady states using time-varying equilibrium force in many-body diffusive systems
Ohad Shpielberg, Takahiro Nemoto
An equivalence between non equilibrium steady states (NESS) driven by a time-independent force and stochastic pumps (SP) stirred by a time-varying conservative force is studied for…
Rare transitions to thin-layer turbulent condensates
Adrian van Kan, Takahiro Nemoto, Alexandros Alexakis
Turbulent flows in a thin layer can develop an inverse energy cascade leading to spectral condensation of energy when the layer height is smaller than a certain threshold. These sp…
How dissipation constrains fluctuations in nonequilibrium liquids: Diffusion, structure and biased interactions
Laura Tociu, Étienne Fodor, Takahiro Nemoto +1
The dynamics and structure of nonequilibrium liquids, driven by non-conservative forces which can be either external or internal, generically hold the signature of the net dissipat…
Universality in dynamical phase transitions of diffusive systems
Ohad Shpielberg, Takahiro Nemoto, João Caetano
Universality, where microscopic details become irrelevant, takes place in thermodynamic phase transitions. The universality is captured by a singular scaling function of the thermo…
Optimizing active work: Dynamical phase transitions, collective motion, and jamming
Takahiro Nemoto, Étienne Fodor, Michael E. Cates +2
Active work measures how far the local self-forcing of active particles translates into real motion. Using Population Monte Carlo methods, we investigate large deviations in the ac…
Method to measure efficiently rare fluctuations of turbulence intensity for turbulent-laminar transitions in pipe flows
Takahiro Nemoto, Alexandros Alexakis
The fluctuations of turbulence intensity in a pipe flow around the critical Reynolds number is difficult to study but important because they are related to turbulent-laminar transi…
Finite-Size Scaling of a First-Order Dynamical Phase Transition: Adaptive Population Dynamics and an Effective Model
Takahiro Nemoto, Robert L. Jack, Vivien Lecomte
We analyze large deviations of the time-averaged activity in the one dimensional Fredrickson-Andersen model, both numerically and analytically. The model exhibits a dynamical phase…
Finite-time and finite-size scalings in the evaluation of large-deviation functions: Analytical study using a birth-death process

The Giardinà-Kurchan-Peliti algorithm is a numerical procedure that uses population dynamics in order to calculate large deviation functions associated to the distribution of time-…
Population dynamics method with a multi-canonical feedback control
Takahiro Nemoto, Freddy Bouchet, Robert L. Jack +1
We discuss the Giardinà-Kurchan-Peliti population dynamics method for evaluating large deviations of time averaged quantities in Markov processes [Phys. Rev. Lett. \textbf{96}, 120…
Finite size effects in a mean-field kinetically constrained model: dynamical glassiness and quantum criticality
Takahiro Nemoto, Vivien Lecomte, Shin-ichi Sasa +1
On the example of a mean-field Fredrickson-Andersen kinetically constrained model, we focus on the known property that equilibrium dynamics take place at a first-order dynamical ph…

Takahiro Nemoto
We study a Brownian particle on a moving periodic potential. We focus on the statistical properties of the work done by the potential and the heat dissipated by the particle. When…
Thermodynamic formula for the cumulant generating function of time-averaged current
Takahiro Nemoto, Shin-ichi Sasa
The cumulant generating function of time-averaged current is studied from an operational viewpoint. Specifically, for interacting Brownian particles under non-equilibrium condition…

Takahiro Nemoto, Shin-ichi Sasa
For Brownian motion of a single particle subject to a tilted periodic potential on a ring, we propose a formula for experimentally determining the cumulant generating function of t…
