Second Quantization-based Symmetry-Adapted Perturbation Theory: Generalizing Exchange Beyond Single Electron Pair Approximation

open access: yes, 2023
This paper presents a general second-quantized form of a permutation operator interchanging $n$ pairs of electrons between interacting subsystems in the framework of the symmetry-adapted perturbation theory (SAPT).

A dichotomy color quantization algorithm for the HSI color space

open access: yesScientific Reports, 2023
Color quantization is used to obtain an image with the same number of pixels as the original but represented using fewer colors. Most existing color quantization algorithms are based on the Red Green Blue (RGB) color space, and there are few color ...

Geometric Quantization and Foliation Reduction [PDF]

open access: yes, 2013
A standard question in the study of geometric quantization is whether symplectic reduction interacts nicely with the quantized theory, and in particular whether “quantization commutes with reduction.” Guillemin and Sternberg first proposed ...

Superposition and second quantization in classical mechanics

open access: yesResults in Physics, 2019
Some natural phenomena can be measured directly, while others are recognized indirectly by clues. In this study, we show that the classical laws of mechanics can be reformulated with entangled labeling-states that experience a collapse.

A Hybrid Color Image Quantization Algorithm Based on K-means and Harmony Search Algorithms [PDF]

open access: yesPort Said Engineering Research Journal, 2015
The importance of color image quantization is reduce the number of different colors in an image with minimum distortion so, it is one of the most important operations in the computer graphics and image processing.

Robust Precoding for Multi-User Visible Light Communications with Quantized Channel Information

open access: yesSensors, 2022
In this paper, we address the design of multi-user multiple-input single-output (MU-MISO) precoders for indoor visible light communication (VLC) systems. The goal is to minimize the transmitted optical power per light emitting diode (LED) under imperfect

The Mathematics of Second Quantization [PDF]

open access: yesProceedings of the National Academy of Sciences, 1951
quantum field theory. Although few nonspecialists have had opportunity to become familiar with the language of modern pure mathematics, quantum theory seems to have reached a point where it must use that language if it is to find a genuine escape from the divergence difficulties.
