Coulomb effects in high-energy e+e− electroproduction by a heavy charged particles in an atomic field

Physics Letters B, 2017
The cross section of high-energy e+e− pair production by a heavy charged particle in the atomic field is investigated in detail. We take into account the interaction with the atomic field of e+e− pair and a heavy particle as well.

Enhanced Optical Cross Section via Collective Coupling of Atomic Dipoles in a 2D Array. [PDF]

Physical Review Letters, 2015
Enhancing the optical cross section is an enticing goal in light-matter interactions, due to its fundamental role in quantum and nonlinear optics. Here, we show how dipolar interactions can suppress off-axis scattering in a two-dimensional atomic array ...

Solar active-sterile neutrino conversion with atomic effects at dark matter direct detection experiments

Journal of High Energy Physics, 2022
The recent XENON1T excess can be explained by the solar active-sterile neutrino conversion with bound electrons via light mediator. Nevertheless, the atomic effects are usually omitted in the solar neutrino explanations.
