Heavy operators and hydrodynamic tails [PDF]

open access: yesSciPost Physics, 2020
The late time physics of interacting QFTs at finite temperature is controlled by hydrodynamics. For CFTs this implies that heavy operators – which are generically expected to create thermal states – can be studied semiclassically. We show that hydrodynamics universally fixes the OPE coefficients

Distinguishing Log-Concavity from Heavy Tails

open access: yesRisks, 2017
Well-behaved densities are typically log-convex with heavy tails and log-concave with light ones. We discuss a benchmark for distinguishing between the two cases, based on the observation that large values of a sum X 1 + X 2 occur as result of a single ...

Impact of correlations and heavy tails on quantum error correction [PDF]

open access: yesPhysical Review A, 2021
We show that space- and time-correlated single-qubit rotation errors can lead to high-weight errors in a quantum circuit when the rotation angles are drawn from heavy-tailed distributions.

The Asymptotics of Moments for the Remaining Time of Heavy-Tail Distributions

open access: yesComputer Sciences & Mathematics Forum, 2023
Recent mathematical models of reliability computer systems and telecommunication networks are based on distributions with heavy tails. This paper falls into the category of exploring the classical models with heavy tails: Gnedenko–Weibull, Burr ...

Understanding Heavy Tails of Flood Peak Distributions

open access: yesWater Resources Research, 2022
Statistical distributions of flood peak discharge often show heavy tail behavior, that is, extreme floods are more likely to occur than would be predicted by commonly used distributions that have exponential asymptotic behavior.

Assessment of temporal change in the tails of probability distribution of daily precipitation over India due to climatic shift in the 1970s

open access: yesJournal of Water and Climate Change, 2021
Daily precipitation extremes are crucial in the hydrological design of major water control structures and are expected to show a changing tendency over time due to climate change.

Inferring heavy tails of flood distributions through hydrograph recession analysis [PDF]

open access: yesHydrology and Earth System Sciences, 2023
Floods are often disastrous due to underestimation of the magnitude of rare events. Underestimation commonly happens when the magnitudes of floods follow a heavy-tailed distribution, but this behavior is not recognized and thus neglected for flood hazard

Estimation of the value-at-risk parameter: Econometric analysis and the extreme value theory approach [PDF]

open access: yesEkonomski Anali, 2006
In this paper different aspects of value-at-risk estimation are considered. Daily returns of CISCO, INTEL and NASDAQ stock indices are analyzed for period: September 1996 - September 2006. Methods that incorporate time varying variability and heavy tails

The Fundamentals of Heavy Tails

open access: yes, 2022
Heavy tails –extreme events or values more common than expected –emerge everywhere: the economy, natural events, and social and information networks are just a few examples. Yet after decades of progress, they are still treated as mysterious, surprising,
