Penning-Trap Searches for Lorentz and CPT Violation
Yunhua Ding, Teague D. Olewiler, Mohammad Farhan Rawnak
An overview of recent progress on testing Lorentz and CPT symmetry using Penning traps is presented. The theory of quantum electrodynamics with Lorentz-violating operators of mass…
Consistent explanation for the cosmic-ray positron excess in p-wave Sommerfeld-enhanced dark matter annihilation
Yu-Chen Ding, Yu-Lin Ku, Chun-Cheng Wei +1
Sommerfeld-enhanced dark matter (DM) annihilation through -wave has been widely considered as a consistent explanation for both the observed cosmic-ray (CR) positron excess and…
Lorentz and CPT tests with charge-to-mass ratio comparisons in Penning traps
Yunhua Ding, Mohammad Farhan Rawnak
Applications of the general theory of quantum electrodynamics with Lorentz- and CPT-violating operators of mass dimensions up to six are presented to Penning-trap experiments compa…
Lorentz and CPT Tests using Penning Traps
Yunhua Ding
The theoretical prospects for quantum electrodynamics with Lorentz-violating operators of mass dimensions up to six are revisited in this work. The dominant effects due to Lorentz…
Comparative Penning-Trap Tests of Lorentz and CPT Symmetry
Yunhua Ding
The theoretical and experimental prospects for Lorentz- and CPT-violating quantum electrodynamics in Penning traps are reviewed in this work. With the recent reported results for t…
Notes on diffusive and shear quasinormal modes of black branes
Yu-Chen Ding, Li Li, Towe Wang
In the literature, to extract the dispersion relation of low-frequency quasinormal modes in both diffusive and shear channels, it is a customary recipe to assume firstly $ω\sim\mat…
