Is Drug Delivery System a Deterministic or Probabilistic Approach? A Theoretical Model Based on the Sequence: Electrodynamics–Diffusion–Bayes

open access: yesMathematics, 2023
Commonly, it is accepted that oncology treatment would yield outcomes with a certain determinism without any quantitative support or mathematical model that establishes such determinations.

The Common Basis of Memory and Consciousness: Understanding the Brain as a Write–Read Head Interacting With an Omnipresent Background Field

open access: yesFrontiers in Psychology, 2020
The main goal of this article consists in addressing two fundamental issues of consciousness research and cognitive science, namely, the question of why declarative memory functions are inextricably linked with phenomenal awareness and the question of ...

Distribution of absorbed photons in the tunneling ionization process

open access: yesScientific Reports, 2021
We describe a procedure that allows us to solve the three-dimensional time-dependent Schrödinger equation for an atom interacting with a quantized one-mode electromagnetic field. Atom-field interaction is treated in an ab initio way prescribed by quantum

Bifurcations in Single Atom Cavity QED [PDF]

open access: yes, 2009
Current research in single-atom cavity quantum electrodynamics largely emphasizes the input-output properties of strongly coupled systems, from normal mode splitting to photon blockade.

Bridging quantum noise and classical electrodynamics with stochastic methods. [PDF]

open access: yesNature Communications
The development of emerging technologies in quantum optics demands accurate models that faithfully capture genuine quantum effects. Mature semiclassical approaches reach their limits when confronted with quantized electromagnetic fields, while full ...

A New Class of Retrocausal Models

open access: yesEntropy, 2018
Globally-constrained classical fields provide a unexplored framework for modeling quantum phenomena, including apparent particle-like behavior. By allowing controllable constraints on unknown past fields, these models are retrocausal but not retro ...

Disagreement between correlations of quantum mechanics and stochastic electrodynamics in the damped parametric oscillator [PDF]

open access: yes, 2000
Intracavity and external third order correlations in the damped nondegenerate parametric oscillator are calculated for quantum mechanics and stochastic electrodynamics (SED), a semiclassical theory.

Quantum framework for describing retarded and nonretarded molecular interactions in external electric fields

open access: yesPhysical Review Research, 2022
We employ various quantum-mechanical approaches for studying the impact of electric fields on both nonretarded and retarded noncovalent interactions between atoms or molecules.

Spontaneous emission in confined space according to stochastic electrodynamics [PDF]

open access: yes, 1992
Modeling an atomic excited state as a simple charged dipole oscillator immersed in a random (zero-point) radiation, we discuss the effects of two metallic plates on the properties of a microscopic system.

Assessment of weak-coupling approximations on a driven two-level system under dissipation

open access: yesNew Journal of Physics, 2021
The standard weak-coupling approximations associated to open quantum systems have been extensively used in the description of a two-level quantum system, qubit, subjected to relatively weak dissipation compared with the qubit frequency.
