Optical transition radiation based transverse beam diagnostics for nonrelativistic ion beams [PDF]

open access: yesPhysical Review Accelerators and Beams, 2022
The usage of optical transition radiation (OTR) for profile monitoring of relativistic electron beams is well known. This paper presents the case for beam diagnostic application of OTR for nonrelativistic ion beams.

Disentangling Cathodoluminescence Spectra in Nanophotonics: Particle Eigenmodes vs Transition Radiation [PDF]

open access: greenNano letters (Print), 2022
Cathodoluminescence spectroscopy performed in an electron microscope has proven a versatile tool for analyzing the near- and far-field optical response of plasmonic and dielectric nanostructures.

Gravitational Waves Induced by Scalar Perturbations during a Gradual Transition from an Early Matter Era to the Radiation Era [PDF]

open access: yesJournal of Physics: Conference Series, 2019
We revisit the effects of an early matter-dominated era on gravitational waves induced by scalar perturbations. We carefully take into account the evolution of the gravitational potential, the source of these induced gravitational waves, during a gradual

Modification of transition radiation by three-dimensional topological insulators [PDF]

open access: yesPhysical review B, 2021
We study how transition radiation is modified by the presence of a generic magnetoelectric medium with a special focus on topological insulators. To this end, we use the Green’s function for the electromagnetic field in presence of a plane interface ...

Photonic and plasmonic transition radiation from graphene [PDF]

open access: yesJournal of Optics, 2020
We theoretically study the transition radiation in the framework of full Maxwell equations, when a swift electron crosses a monolayer graphene. Based on the Sommerfeld integration, we demonstrate in the frequency domain the spatial distribution of this ...

Generation of Terawatt Attosecond Pulses from Relativistic Transition Radiation. [PDF]

open access: yesPhysical Review Letters, 2020
When a femtosecond duration and hundreds of kiloampere peak current electron beam traverses the vacuum and high-density plasma interface, a new process, that we call relativistic transition radiation (RTR), generates an intense ∼100 as pulse containing ...

Transition radiation from a Dirac-particle wave packet traversing a mirror [PDF]

open access: yesPhysical Review A, 2020
The explicit expression for the inclusive probability to record a photon created in transition radiation from a one Dirac particle wave packet traversing an ideally conducting plate is derived in the leading order of perturbation theory.

Controlling Cherenkov angles with resonance transition radiation [PDF]

open access: yesConference on Lasers and Electro-Optics, 2018
Cherenkov radiation provides a valuable way to identify high-energy particles in a wide momentum range, through the relation between the particle velocity and the Cherenkov angle.

Coherent Transition Radiation from the Geomagnetically Induced Current in Cosmic-Ray Air Showers: Implications for the Anomalous Events Observed by ANITA. [PDF]

open access: yesPhysical Review Letters, 2019
We show that coherent transition radiation from the electrically neutral transverse geomagnetic current (CTR-GM) in a cosmic-ray air shower provides a natural, standard model, explanation to the recent "anomalous" events observed by the ANITA detector ...

Driving positron beam acceleration with coherent transition radiation

open access: yesCommunications Physics, 2020
Positron acceleration in plasma wakefield faces significant challenges, as the positron beam must be pre-generated and precisely coupled into the wakefield and, most critically, suffers from defocusing issues. Here we propose a scheme that utilizes laser-
