Power law correlations in the Southern Oscillation Index fluctuations characterizing El Nino
The essentials
- Study by M. Ausloos and K. Ivanova analyzes the Southern Oscillation Index (SOI) in relation to El Nino
- Examined monthly averaged SOI data from 1866 to 2000
- Large fluctuations in SOI signal were more common than expected based on Gaussian distribution
- Utilized energy spectrum analysis and Detrended Fluctuation Analysis (DFA) methods
- Results showed self-affine properties and power law correlations in the SOI signal
- Antipersistent correlations found within a specific time interval of 4 months to 6 years
- Suggests some predictability in El Nino event behavior over this timeframe
- Findings provide insights into dynamics of El Nino events and support physical models for prediction

Tsallis nonextensive statistical mechanics of El Nino Southern Oscillation IndexM. Ausloos, F. Petroni · 2006 · Physica A 373 (2007) 721 - 736 · AI summary available
Abstract
The shape and tails of partial distribution functions (PDF) for a climatological signal, i.e. the El Nino SOI and the turbulent nature of the ocean-atmosphere variability are linked through a model encompassing Tsallis nonextensive statistics and leading to evolution equations of the Langevin and Fokker-Planck type. A model originally proposed to describe the intermittent behavior of turbulent flows describes the behavior of the normalized variability for such a climatological index, for small and large time windows, both for small and large variability. This normalized variabil- ity distributions can be sufficiently well fitted with a chi-square-distribution. The transition between the smal…

Power-law exponent in multiplicative Langevin equation with temporally correlated noiseSatoru Morita · 2017 · Journal of the Physical Society of Japan 87, 053801 (2018) · Not summarized yet
Abstract
Power-law distributions are ubiquitous in nature. Random multiplicative processes are a basic model for the generation of power-law distributions. It is known that, for discrete-time systems, the power-law exponent decreases as the autocorrelation time of the multiplier increases. However, for continuous-time ystems, it has not yet been elucidated as to how the temporal correlation affects the power-law behavior. Herein, we have analytically investigated a multiplicative Langevin equation with colored noise. We show that the power-law exponent depends on the details of the multiplicative noise, in contrast to the case of discrete-time systems.

Statistical optimization for passive scalar transport: maximum entropy production vs maximum Kolmogorov-Sinay entropyMartin Mihelich, Berengere Dubrulle, Didier Paillard et al. · 2015 · Statistical Mechanics · AI summary available
Abstract
We derive rigorous results on the link between the principle of maximum entropy production and the principle of maximum Kolmogorov-Sinai entropy using a Markov model of the passive scalar diffusion called the Zero Range Process. We show analytically that both the entropy production and the Kolmogorov-Sinai entropy seen as functions of f admit a unique maximum denoted fmaxEP and fmaxKS. The behavior of these two maxima is explored as a function of the system disequilibrium and the system resolution N. The main result of this article is that fmaxEP and fmaxKS have the same Taylor expansion at _rst order in the deviation of equilibrium. We find that fmaxEP hardly depends on N whereas fmaxKS dep…

Drift-Controlled Anomalous Diffusion: A Solvable Gaussian ModelFabrizio Lillo, Rosario N. Mantegna · 2000 · Statistical Mechanics · AI summary available
Abstract
We introduce a Langevin equation characterized by a time dependent drift. By assuming a temporal power-law dependence of the drift we show that a great variety of behavior is observed in the dynamics of the variance of the process. In particular diffusive, subdiffusive, superdiffusive and stretched exponentially diffusive processes are described by this model for specific values of the two control parameters. The model is also investigated in the presence of an external harmonic potential. We prove that the relaxation to the stationary solution is power-law in time with an exponent controlled by one of model parameters.

Classical limit of measurement-induced transition in many-body chaos in integrable and non-integrable oscillator chainsSibaram Ruidas, Sumilan Banerjee · 2022 · Statistical Mechanics · AI summary available
Abstract
We discuss the dynamics of integrable and non-integrable chains of coupled oscillators under continuous weak position measurements in the semiclassical limit. We show that, in this limit, the dynamics is described by a standard stochastic Langevin equation, and a measurement-induced transition appears as a noise- and dissipation-induced chaotic-to-non-chaotic transition akin to stochastic synchronization. In the non-integrable chain of anharmonically coupled oscillators, we show that the temporal growth and the ballistic light-cone spread of a classical out-of-time correlator characterized by the Lyapunov exponent and the butterfly velocity, are halted above a noise or below an interaction s…

Fluctuation-induced spin nematic order in magnetic charge-iceA. Hemmatzade, K. Essafi, M. Taillefumier et al. · 2023 · Statistical Mechanics · AI summary available
Abstract
Disorder in materials may be used to tune their functionalities, but much more strikingly, its presence can entail entirely new behavior. This happens in charge-ice where structural disorder is not weak and local, but strong and long-range correlated. Here, two cations of different charge occupy a pyrochlore lattice, arranging themselves such that all tetrahedra host two cations of each type. The ensuing correlated disorder is characterized by randomly packed loops of a single cation-type. If the cations are magnetic and interact antiferromagnetically, a new type of magnet with strong interactions along the loops, but frustrated interactions between loops, emerges. This results in an ensembl…

Field Theory of BirhythmicitySergei Shmakov, Peter B. Littlewood · 2025 · Statistical Mechanics · AI summary available
Abstract
Non-equilibrium dynamics are present in many aspects of our lives, ranging from microscopic physical systems to the functioning of the brain. What characterizes stochastic models of non-equilibrium processes is the breaking of the fluctuation-dissipation relations as well as the existence of non-static stable states, or phases. A prototypical example is a dynamical phase characterized by a limit cycle - the order parameter of finite magnitude rotating or oscillating at a fixed frequency. Consequently, birhythmicity, where two stable limit cycles coexist, is a natural extension of the simpler single limit cycle phase. Both the abundance of real systems exhibiting such states as well as their …

How are these papers found?
We compare the title and abstract of this paper with those of every paper summarized on this site, and with the papers Semantic Scholar recommends, those it cites and those citing it (for a much-cited paper, its most recent citations and, from OpenAlex, the most cited ones). Among the prior work and the follow-ups, the papers that use each other in depth, a method it uses and the much-cited follow-ups come a little higher. The levels (very close, close, related) come from the similarity of the texts, not from a judgment of quality; * marks a paper without an abstract, compared by its title. The sentence under a paper is written by an AI from the two abstracts: check it in the papers. A paper marked not relevant by three readers leaves the list.
For now only among the papers summarized on this site: search again to add the prior work, the follow-ups and Semantic Scholar’s recommendations.
