Effective-medium approach to the resonance distribution of wave scattering in a random point field
David Gaspard, Jean-Marc Sparenberg
In a previous paper [Phys. Rev. A 105, 042205 (2022)], the distribution of resonance poles in the complex plane of the wavenumber associated to the multiple scattering of a qua…
Transverse quantum decoherence of a fast particle in a gas
David Gaspard, Jean-Marc Sparenberg
The decoherence of a fast quantum particle in a gas is studied by applying the Kramers-Moyal expansion to the quantum master equation for the reduced density matrix of the particle…
Quantum master equations for a fast particle in a gas
David Gaspard
The propagation of a fast particle in a low-density gas at thermal equilibrium is studied in the context of quantum mechanics. A quantum master equation in the Redfield form govern…
Resonance distribution in the quantum random Lorentz gas
David Gaspard, Jean-Marc Sparenberg
The multiple scattering model of a quantum particle in a random Lorentz gas consisting of fixed point scatterers is considered in arbitrary dimension. An efficient method is develo…
Multiple scattering model of the quantum random Lorentz gas
David Gaspard, Jean-Marc Sparenberg
A multiple scattering model of a quantum particle interacting with a random Lorentz gas of fixed point scatterers is established in an Euclidean space of arbitrary dimension. At th…
Complex-energy analysis of proton-proton fusion
David Gaspard, Jean-Marc Sparenberg, Quentin Wenda +1
An analysis of the astrophysical factor of the proton-proton weak capture () is performed on a larg…
Connection formulas between Coulomb wave functions
David Gaspard
The mathematical relations between the regular Coulomb function and the irregular Coulomb functions and are obtained in the complex…
Effective-range function methods for charged particle collisions
David Gaspard, Jean-Marc Sparenberg
Different versions of the effective-range function method for charged particle collisions are studied and compared. In addition, a novel derivation of the standard effective-range…
Decoherence and determinism in a one-dimensional cloud-chamber model
Jean-Marc Sparenberg, David Gaspard
The hypothesis by Sparenberg et al. (2013) that the particular linear tracks appearing in the measurement of a spherically-emitting radioactive source in a cloud chamber are determ…
