Net-particle number fluctuations in a hydrodynamic description of heavy-ion collisions [PDF]
EPJ Web of Conferences, 2022 Utilizing viscous hydrodynamic simulations of heavy-ion collisions, we study the behavior of cumulants of (net-)(anti)proton number distributions at RHIC beam energy scan energies, incorporating non-critical contributions like baryon conservation and ...

Numerical Generation of Trajectories Statistically Consistent with Stochastic Differential Equations. [PDF]
Entropy (Basel)A weak second-order numerical method for generating trajectories based on stochastic differential equations (SDE) is developed. The proposed approach bypasses direct noise realization by updating the system’s state using independent Gaussian random ...

Effects of Initial Density Fluctuations on Cumulants in Au + Au Collisions at
Universe, 2022 Within the ultrarelativistic quantum molecular dynamics (UrQMD) model, the effect of initial density fluctuations on cumulants of the net-proton multiplicity distribution in Au + Au Collisions at sNN = 7.7 GeV was investigated by varying the minimum ...

A Fourier-cumulant analysis for multiharmonic flow fluctuation
European Physical Journal C: Particles and Fields, 2021 The Fourier analysis of the final particle distribution followed by cumulant study of the Fourier coefficient event-by-event fluctuation is one of the main approaches for testing the collective evolution in the heavy-ion collision.

Analogs of the Prime Number Problem in a Shot Noise Suppression of the Soft-Reset Process. [PDF]
Nanomaterials (Basel)The soft-reset process, or a sequence of charge emissions from a floating storage node through a transistor biased in a subthreshold bias condition, is modeled by a master (Kolmogorov–Bateman) equation.

Empirical estimation of realized higher-order (joint) cumulants and their practical issues [PDF]
Seonmul yeonguAs conventional realized third and fourth (co)moments estimated with sub-period returns are biased, Neuberger (2012) and Bae and Lee (2021) develop new unbiased realized (joint) cumulants using extended information.
