Exponential Decay of Correlations Implies Area Law [PDF]

Communications in Mathematical Physics, 2014
We prove that a finite correlation length, i.e. exponential decay of correlations, implies an area law for the entanglement entropy of quantum states defined on a line. The entropy bound is exponential in the correlation length of the state, thus reproducing as a particular case Hastings proof of an area law for groundstates of 1D gapped Hamiltonians ...

Index option returns and systemic equity risk

Journal of Finance and Data Science, 2018
In an environment characterized by stochastic variances and correlations, we demonstrate through construction of the equilibrium index option value from constituent components, that the generalized PDE identifies the stochastic elements differentially ...

Implied motion activation in cortical area MT can be explained by visual low-level features [PDF]

, 2011
To investigate form-related activity inmotion-sensitive cortical areas, we recorded cell responses to animate implied motion in macaque middle temporal (MT) and medial superior temporal (MST) cortex and investigated these areas using fMRI in humans.

Newborn Weight and Second-Hand Smoking in Utero Exposure: A Case in A Low-Middle Income Country

Jurnal Keperawatan Soedirman, 2023
Smoking exposure among pregnant women is correlated with the risk of low birth weight. The policy factors are believed to contribute to the rate or prevalence of smoking activities.

Numerical Simulation of the Heston Model under Stochastic Correlation

International Journal of Financial Studies, 2017
Stochastic correlation models have become increasingly important in financial markets. In order to be able to price vanilla options in stochastic volatility and correlation models, in this work, we study the extension of the Heston model by imposing ...
