The von Neumann entropy asymptotics in multidimensional fermionic systems

open access: yes, 2011
We study the von Neumann entropy asymptotics of pure translation-invariant quasi-free states of d-dimensional fermionic systems. It is shown that the entropic area law is violated by all these states: apart from the trivial cases, the entropy of a cubic ...

Conditional entropy of ordinal patterns [PDF]

open access: yes, 2014
In this paper we investigate a quantity called conditional entropy of ordinal patterns, akin to the permutation entropy. The conditional entropy of ordinal patterns describes the average diversity of the ordinal patterns succeeding a given ordinal ...

Effect of serrated grain boundary on tensile and creep properties of a precipitation strengthened high entropy alloy

open access: yesScience and Technology of Advanced Materials, 2023
In this study, tensile and creep deformation of a high-entropy alloy processed by selective laser melting (SLM) has been investigated; hot ductility drop was identified at first, and the loss of ductility at elevated temperature was associated with ...

Entropy and Entropy Production in Some Applications

open access: yes, 2013
By using entropy and entropy production, we calculate the steady flux of some phenomena. The method we use is a competition method, $S_S/\tau+\sigma={\it maximum}$, where $S_S$ is system entropy, $\sigma$ is entropy production and $\tau$ is microscopic ...

Non-Value-Added Tax to improve market fairness and quality

open access: yesFinancial Innovation, 2022
The promotion of both market fairness and efficiency has long been a goal of securities market regulators worldwide. Accelerated digital disruption and abusive trading behaviors, such as the GameStop mania, prompt regulatory changes.

Generalised exponential families and associated entropy functions

open access: yes, 2008
A generalised notion of exponential families is introduced. It is based on the variational principle, borrowed from statistical physics. It is shown that inequivalent generalised entropy functions lead to distinct generalised exponential families.

Data to reproduce and modify “An approach for screening single phase high-entropy alloys using an in-house thermodynamic database”

open access: yesData in Brief, 2018
XRD raw data of the milled and heat-treated Co,Fe,Mn,Ni,Zn-containing high-entropy alloys (HEAs) is presented. Complete description of the quaternary, quinary and senary binary priority lists, including the names of the most relevant binary sets of ...

Max- relative entropy of coherence: an operational coherence measure

open access: yes, 2017
The operational characterization of quantum coherence is the corner stone in the development of resource theory of coherence. We introduce a new coherence quantifier based on max-relative entropy.
