Light-cone quantization of scalar field on time-dependent backgrounds

European Physical Journal C: Particles and Fields, 2022
We discuss what is light-cone quantization on a curved spacetime also without a null Killing vector. Then we consider as an example the light-cone quantization of a scalar field on a background with a Killing vector and the connection with the second ...

A dichotomy color quantization algorithm for the HSI color space

Scientific 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 ...

Second Quantization of the Wilson Loop [PDF]

, 1994
Treating the QCD Wilson loop as amplitude for the propagation of the first quantized particle we develop the second quantization of the same propagation.

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

Port 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.

Quantum state diffusion, measurement and second quantization [PDF]

, 1999
Realistic dynamical theories of measurement based on the diffusion of quantum states are nonunitary, whereas quantum field theory and its generalizations are unitary.

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

Sensors, 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

Quasi-free “second quantization” [PDF]

Communications in Mathematical Physics, 1976
Araki and Wyss considered in 1964 a mapA→Q(A) of one-particle trace-class observables on a complex Hilbert-space ℋ into the fermionC*-algebraU(ℋ) over ℋ. In particular they considered this mapping in a quasi-free representation.

Superposition and second quantization in classical mechanics

Results 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.
