The relation between quantum and classical field theory with a classical source: Field theory with a classical source
(2020-01-01)
Classical field theory is about fields and how they behave in space-time. Quantum field theory, in practice, usually seems to be about particles and how they scatter. Nevertheless, classical fields must emerge from quantum ...
Crossing the phantom divide with a classical Dirac field
(Springer, 2011-01)
In this paper we consider a spatially flat Friedmann-Robertson-Walker (FRW) cosmological model with cosmological constant, containing a stiff fluid and a classical Dirac field. The proposed cosmological scenario describes ...
The classical limit of non-integrable quantum systems, a route to quantum chaos
(Elsevier, 2006-04)
The classical limit of non-integrable quantum systems is studied. We define non-integrable quantum systems as those, which have, as their classical limit, a non-integrable classical system. This quantum systems will be the ...
The large electron model: the classical background of Compton effect
(2011)
Arthur Holly Compton's persona is usually conceived as one of the founder fathers of the quantum mechanics due to his quantum formulation to explain the process of interaction between the high-frequency radiation and matter. ...
Classical field theory
(2019-01-01)
Classical field theory predicts how physical fields interact with matter, and is a logical precursor to quantum field theory. This introduction focuses purely on modern classical field theory, helping graduates and researchers ...
Scaling laws in the quantum-to-classical transition in chaotic systems
(American Physical Society, 2009-02)
We study the quantum-to-classical transition in a chaotic system surrounded by a diffusive environment. First, we analyze the emergence of classicality when it is monitored by the Renyi entropy, a measure of the entanglement ...
The subcellular localization and physiological roles of estrogen receptors α and β in classical and non-classical tissues
(Nova Science Publishers, 2017)
It is now firmly established that estrogens elicit a variety of rapid effects in many tissues in addition to their delayed action on gene expression in the cell nucleus. Moreover, the classic estrogen receptors have been ...
Quantum-to-classical transition in a system with mixed classical dynamics
(American Physical Society, 2006-12)
We study how decoherence rules the quantum-classical transition of the kicked harmonic oscillator. The system presents classical dynamics that ranges from regular to strong chaotic behavior depending on the amplitude of ...
