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 ...

Stability of numerical method for semi-linear stochastic pantograph differential equations

open access: yesJournal of Inequalities and Applications, 2016
As a particular expression of stochastic delay differential equations, stochastic pantograph differential equations have been widely used in nonlinear dynamics, quantum mechanics, and electrodynamics.

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

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 ...

Spontaneous dressed-state polarization in the strong driving regime of cavity QED [PDF]

open access: yes, 2009
We utilize high-bandwidth phase quadrature homodyne measurement of the light transmitted through a Fabry-Perot cavity, driven strongly and on resonance, to detect excess phase noise induced by a single intracavity atom.

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.

Multi-Qubit Joint Measurements in Circuit QED: Stochastic Master Equation Analysis [PDF]

open access: yes, 2016
We derive a family of stochastic master equations describing homodyne measurement of multi-qubit diagonal observables in circuit quantum electrodynamics.

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.

Stochasticity effects in quantum radiation reaction [PDF]

open access: yes, 2013
When an ultrarelativistic electron beam collides with a sufficiently intense laser pulse, radiation-reaction effects can strongly alter the beam dynamics.
