A determination of the backscattering probability of low-energy antiprotons
GBAR Collaboration, K. Park, E. Perez +42
It is commonly assumed that antiprotons impinging on a material surface annihilate promptly with the nuclei of the material. However, at kinetic energies of a few keV, this assumpt…

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…
