Shadows and accretion disk images of charged rotating black hole in modified gravity theory by He-Bin Zheng, Meng-Qi Wu, Guo-Ping Li, Qing-Quan Jiang

“…Interestingly, as $$\alpha $$ α increases, the flat edge of the BH’s shadow gradually becomes more rounded, the size of shadow enlarges, and the deviation rate ( $$\delta s$$ δ s ) correspondingly decreases. By tracing the photon around BH, we observe that the trajectory of photon exhibits distortion behavior, i.e., the formation of two “tails” near the Einstein ring, which elongate as a increases. …”

Reimagining e+e− collider precision luminosity measurements by Wilson Graham, Madison Brendon

“…It will also serve as a general forward electromagnetic calorimeter helping ensure hermeticity and detecting individual electrons, positrons, and photons. In this contribution we highlight the Bhabha rejection capability in the context of the e+e− → γγ luminosity measurement and motivate the utility of a Bhabha “mini-tracker” consisting of a few planes of upstream thin silicon detectors. …”

Scalable Networking of Neutral-Atom Qubits: Nanofiber-Based Approach for Multiprocessor Fault-Tolerant Quantum Computers by Shinichi Sunami, Shiro Tamiya, Ryotaro Inoue, Hayata Yamasaki, Akihisa Goban

“…To overcome this challenge, we clarify the criteria and technological requirements for further scaling based on multiple neutral atom quantum processing units (QPUs) connected through photonic networking links. Our quantitative analysis shows that nanofiber optical cavities have the potential as an efficient atom-photon interface to enable fast entanglement generation between atoms in distinct neutral-atom modules, allowing multiple neutral-atom QPUs to operate cooperatively without sacrificing computational speed. …”
