Nonperturbative quantization ‘a la Heisenberg for non-Abelian gauge theories: two-equation approximation. Applications: a flux tube solution and a scalar model of glueball

EPJ Web of Conferences, 2017
The nonperturbative quantization technique à la Heisenberg is applied for the SU(3) gauge theory. The operator Yang-Mills equation and corresponding infinite set of equations for all Green’s functions are considered. Gauge degrees of freedom are splitted

A Program Library for Computing Pure Spin-Angular Coefficients for One- and Two-Particle Operators in Non-Relativistic Atomic Theory

Atoms
A program library, libang77, for computing pure spin-angular coefficients for any one- and scalar two-particle operator is presented. The method is based on the combination of the second quantization and quasi-spin techniques with angular momentum theory

Towards Efficient AI: A Survey of Model Compression Techniques on the Edge [PDF]

Jisuanji gongcheng
A considerable structural contradiction exists between the surge in the parameter scale of Large Language Models (LLMs) and the limited physical resources of edge terminals, which restricts their large-scale deployment.

Unsupervised Classification of Hydrophone Signals With an Improved Mel-Frequency Cepstral Coefficient Based on Measured Data Analysis

IEEE Access, 2019
Recently, passive detection technology has developed the ability to detect surface ships based on the noise emissions recorded by hydrophones, making it possible in some cases to classify surface ships.

Stochastic integral representations of second quantization operators

Journal of Functional Analysis, 2004
The author proves that the second quantization \(\Gamma (h)\) of a bounded operator \(h\) on \(L^2 ({\mathbb R}_+)\) can be represented as a quantum stochastic integral if and only if \(h\) admits a decomposition as the sum of a Hilbert-Schmidt operator \(K\) and an operator \(M\) of multiplication by an essentially bounded function.

Second quantization and evolution operators in infinite dimension

Journal of Functional Analysis
In an infinite dimensional separable Hilbert space $X$, we study compactness properties and the hypercontractivity of the Ornstein-Uhlenbeck evolution operators $P_{s,t}$ in the spaces $L^p(X,γ_t)$, $\{γ_t\}_{t\in\R}$ being a suitable evolution system of measures for $P_{s,t}$. Moreover, we study the asymptotic behavior of $P_{s,t}$.
