Distribution of absorbed photons in the tunneling ionization process

Scientific 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

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

Journal 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.

A New Class of Retrocausal Models

Entropy, 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 ...

The Zero-Point Field and Inertia [PDF]

, 1998
A brief overview is presented of the basis of the electromagnetic zero-point field in quantum physics and its representation in stochastic electrodynamics.

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

Physical 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.

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

New 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.

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

, 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.

Stochasticity effects in quantum radiation reaction [PDF]

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

From Stochastic Optics to theWigner Formalism: The Role of the Vacuum Field in Optical Quantum Communication Experiments

Atoms, 2019
TheWigner formalism in the Heisenberg picture constitutes a bridge that connects QuantumOptics to Stochastic Optics. The vacuum field appears explicitly in the formalism, and the wavelikeaspects of light are emphasised.
