First measurement of the antihydrogen production cross section through the charge-exchange reaction of low-energy antiprotons with orthopositronium
GBAR Collaboration, P. Adrich, I. Belosevic +42
The GBAR experiment has measured the formation rate of antihydrogen from antiproton impact on a positronium cloud for antiproton kinetic energies of 4 and 6 keV. This is the first…
Monitoring antiproton numbers with a CMOS detector in a dense-track environment
C. Regenfus, P. Adrich, I. Belosevic +42
The production of antihydrogen by the GBAR experiment at AD/ELENA requires good knowledge of the number of incident keV antiprotons, which can be problematic. We have used a commer…
Probing the Weak-Driving Quantum Speed Limit via Drift-Aware Shooting Methods
Denis Janković, Saba Taherpour, Paul-Louis Etienney +2
A central goal of quantum optimal control is to achieve high-fidelity and low-energy control pulses. When quantum optimal control methods optimize every point of a pulse discretize…
Optimal Quantum Feshbach Engines
Aaron Wandhammer, Vincent Hardel, Paul-Antoine Hervieux +1
We develop an optimization framework for high-efficiency quantum cycles implemented with a trapped Bose-Einstein condensate, whose control parameters are the trap stiffness and the…
Record accumulation of antiprotons in a Penning-Malmberg Trap and their preparation for improved production of antihydrogen beams
B. Lee, B. Kim, P. Adrich +35
CERN's AD/ELENA ``antimatter factory'' - unique worldwide - serves several experiments, all of which use electromagnetic traps to accumulate antiprotons for fundamental science. Th…
Fast and Smooth Quantum Unitary Control of High-Dimensional Spin-Qudits via a Shooting Technique
Paul-Louis Etienney, Denis Janković, Killian Lutz +3
High-fidelity quantum control is a cornerstone of scalable quantum technologies. We introduce a shooting-based optimization framework that generates smooth, experimentally realisti…
The hyperfine interaction as a probe of the microscopic structure of the atomic nucleus
Denis Janković, Jean-Gabriel Hartmann, Johann Bartel +3
The study of highly charged electronic and muonic hydrogen-like ions, provides an intriguing way to probe the internal structure of their atomic nuclei. In this work, we use nuclea…
Shake-up and shake-off spectra in the electron capture decay of atomic Be
Mauro Guerra, Inwook Kim, Stephan Friedrich +33
The most stringent laboratory-based experimental limits on the existence of sub-MeV sterile neutrinos are currently set by decay spectroscopy of radioactive Be embedded into su…
