Monte Carlo Study of Pure-Phase Cumulants of 2D q-State Potts Models [PDF]

open access: yes, 1997
We performed Monte Carlo simulations of the two-dimensional q-state Potts model with q=10, 15, and 20 to study the energy and magnetization cumulants in the ordered and disordered phase at the first-order transition point $\beta_t$.

Optimal escape from metastable states driven by non-Gaussian noise [PDF]

open access: yes, 2015
5 pages, 2 figures5 pages, 2 figures5 pages, 2 figuresWe investigate escape processes from metastable states that are driven by non-Gaussian noise. Using a path integral approach, we define a weak-noise scaling limit that identifies optimal escape paths ...

Blind recognition of STBC based on higher-order cumulants

open access: yesTongxin xuebao, 2016
Aiming at the problems for blind recognition of space-time block code(STBC)in MIMO communication sys-tems,a method was exploited based on higher-order cumulants of received signals.Firstly,the model of received signals was given and the fourth-order ...

Ott-Antonsen ansatz truncation of a circular cumulant series

open access: yesPhysical Review Research, 2019
The cumulant representation is common in classical statistical physics for variables on the real line and the issue of closures of cumulant expansions is well elaborated. The case of phase variables significantly differs from the case of linear ones; the

Statistical temporal pattern extraction by neuronal architecture

open access: yesPhysical Review Research, 2023
Neuronal systems need to process temporal signals. Here, we show how higher-order temporal (co)fluctuations can be employed to represent and process information.

Baryon number conservation and the cumulants of the net proton distribution

open access: yes, 2012
We discuss the modification of the cumulants of the net baryon and net proton distributions due to the global conservation of baryon number in heavy-ion collisions. Corresponding probability distributions and their cumulants are derived analytically.

Higher Order Cumulants and Inference for a Class of Filtered Poisson Processes

open access: yesAustrian Journal of Statistics, 2016
Spectral methods are useful in the analysis of time series and point process data in Zd or Rd. Parameter estimates based on these often have a limiting Gaussian distribution, whose limiting variance depends upon integrals of the second, third and fourth ...

Improved resolving capabilities of linear array using 2qth order non‐circular statistics

open access: yesIET Signal Processing, 2021
Resolving more sources than sensors is always of interest to researchers. For this purpose, generation of the virtual array from the non‐uniform linear array has recently gathered a lot of attention.

Direction-of-Arrival Estimation Based on Sparse Representation of Fourth-Order Cumulants

open access: yesIEEE Access, 2023
The actual underwater environmental noise is often spatial colored, which results in severe degradation of the performance of the underwater direction of arrival (DOA) estimation method based on the assumption of white noise.

Probing the QCD phase diagram with fluctuations

open access: yes, 2014
The relevance of higher order cumulants of conserved charges for the analysis of freeze-out and critical conditions in heavy ion collisions at LHC and RHIC is discussed.
