We study the role of long-range dipolar interactions on antiferromagnetic spin chains, from the classical S→ limit to the deep quantum case S=1/2, including a transverse magnetic field. To this end, we combine different ...

This paper addresses the estimation of locally stationary long-range dependent processes, a methodology that allows the statistical analysis of time series data exhibiting both nonstationarity and strong dependency. A ...

Se presenta un sistema de monitoreo remoto de sensores de monóxido de carbono (CO) en un hospital usando transceptores Long-Range. Un gas altamente tóxico que no puede ser detectado por el ser humano y que causa daños ...

Some asymptotic statistical properties of the sample mean of a class locally stationary long-memory process are studied in this paper. Conditions for consistency are investigated and precise convergence rates of the variance ...

The depinning transition of elastic interfaces with an elastic interaction kernel decaying as 1/rd+σ is characterized by critical exponents which continuously vary with σ. These exponents are expected to be unique and ...

Long-range memory in time series is often quantified by the Hurst exponent H, a measure of the signal's variance across several time scales. We analyze neurophysiological time series from electroencephalography (EEG) and ...

A numerically efficient transfer matrix approach is used to investigate the validity of the Tsallis scaling hypothesis in the long-range Ising spin chain with competitive interactions. In this model, the interaction between ...
