Holomorphic anomaly of 2d Yang-Mills theory on a torus revisited

open access: yesJournal of High Energy Physics, 2019
We study the large N ’t Hooft expansion of the chiral partition function of 2d U(N) Yang-Mills theory on a torus. There is a long-standing puzzle that no explicit holomorphic anomaly equation is known for the partition function, although it admits a ...

Artificial Intelligence Knowledge Graph for Dynamic Networks: An Incremental Partition Algorithm

open access: yesIEEE Access, 2020
The quick and intelligent requests and answers in artificial intelligence (AI) are inseparable from intelligent data. Knowledge graph makes data more intelligent by establishing association among data, which provides convenience for intelligent search ...

Calculation of thermodynamic properties and transport parameters of C6F12O

open access: yesFrontiers in Materials, 2022
C6F12O has good insulating properties and has the potential to be used as an insulating medium in gas-insulated equipment. Previous researches show that thermodynamic properties and transport parameters can reflect the microscopic properties of plasma ...

Joint multifractal analysis based on the partition function approach: analytical analysis, numerical simulation and empirical application

open access: yesNew Journal of Physics, 2015
Many complex systems generate multifractal time series which are long-range cross-correlated. Numerous methods have been proposed to characterize the multifractal nature of these long-range cross correlations.

Microscopic entropy of rotating electrically charged AdS4 black holes from field theory localization

open access: yesJournal of High Energy Physics, 2020
We employ supersymmetric localization to determine the exact partition function of 3d N $$ \mathcal{N} $$ = 2 gauge theories on a background given by a round S 2 fibered over a circle and certain complexified background fields.

Stochastic Theory of Discrete Binary Fragmentation—Kinetics and Thermodynamics

open access: yesEntropy, 2022
We formulate binary fragmentation as a discrete stochastic process in which an integer mass k splits into two integer fragments j, k−j, with rate proportional to the fragmentation kernel Fj,k−j.

Nonmonotonic pressure as a function of the density in a fluid without attractive forces

open access: yesCondensed Matter Physics, 2013
A simple result for the pressure of a hard sphere fluid that was developed many years ago by Rennert is extended in a straightforward manner by adding additional terms that are of the same form as Rennert's formula. The resulting expression is moderately

STATISTICAL MECHANICS: BRIDGING MICROSCOPIC BEHAVIOR TO MACROSCOPIC OBSERVABLES: Gravitational waves

open access: yesWorldwide Journal of Physics, 2023
This study investigates how statistical mechanics bridges the gap between microscopic particle dynamics and macroscopic thermodynamic observables through a mixed-methods framework combining ensemble theory, computational modeling, and statistical ...

On the Wigner-Kirkwood Expansion of the Free Energy and the Evaluation of the Quantum Correction

open access: yesAtoms, 2022
The Wigner-Kirkwood expansion of the quantum correction to the classical free energy is generally said to be in powers of ℏ2 and only its first few terms are presented.
