Soft-Phonon-Driven Effective Inversion-Symmetry Crossover in Quantum Paraelectrics
Xiaojiang Li, Guodong Zhao, Fei Yang +6
Symmetry lays the foundation of condensed matter physics and its experimental manifestation provides fundamental insight into the collective behaviors of quantum materials. Optical…
Measurement of the nucleon spin structure functions for 0.01<<1 GeV using CLAS
A. Deur, S. E. Kuhn, M. Ripani +147
The spin structure functions of the proton and the deuteron were measured during the EG4 experiment at Jefferson Lab in 2006. Data were collected for longitudinally polarized elect…
Optimizing Antihydrogen Production via Slow Plasma Merging
E D Hunter, M Bumbar, C Amsler +29
We measure the time-dependent temperature and density distribution of antiprotons and positrons while slowly combining them to make antihydrogen atoms in a nested Penning-Malmberg…
Measured Properties of an Antihydrogen Beam
E. D. Hunter, M. Bumbar, C. Amsler +29
We report a factor of increase in the antihydrogen beam intensity downstream of ASACUSA's Cusp trap: atoms detected per -minute run. The beam contains many Rydberg…
Towards a Study of Low Energy Antiproton Annihilations on Nuclei
Viktoria Kraxberger, Marcus Bumbar, Angela Gligorova +30
A study of antiproton annihilations at rest on thin solid targets is underway at the ASACUSA facility, which now features a dedicated beam line for slow extraction at 250 eV. The e…
