Narrow spectra of repeating fast radio bursts: A magnetospheric origin

Kavli Affiliate: Renxin Xu | First 5 Authors: Wei-Yang Wang, Yuan-Pei Yang, Hong-Bo Li, Jifeng Liu, Renxin Xu | Summary: Fast radio bursts (FRBs) can present a variety of polarization properties, and some of them have narrow spectra. We study spectral properties from perspectives of intrinsic radiation mechanisms and absorption during the waves propagating in […]

KMT-2023-BLG-1431Lb: A New $q < 10^{-4}$ Microlensing Planet from a Subtle Signature

Kavli Affiliate: Subo Dong | First 5 Authors: Aislyn Bell, Jiyuan Zhang, Youn Kil Jung, Jennifer C. Yee, Hongjing Yang | Summary: The current studies of microlensing planets are limited by small number statistics. Follow-up observations of high-magnification microlensing events can efficiently form a statistical planetary sample. Since 2020, the Korea Microlensing Telescope Network (KMTNet) […]

New limits on the local Lorentz invariance violation of gravity in the Standard-Model Extension with pulsars

Kavli Affiliate: Lijing Shao | First 5 Authors: Yiming Dong, Ziming Wang, Lijing Shao, , | Summary: Lorentz Invariance Violation (LIV) is posited as a possible relic effect of quantum gravity at low energy scales. The Standard-Model Extension provides an effective field-theoretic framework for examining possible deviations attributed to LIV. With the observations of the […]

Josephson Diode Effect in Topological Superconductor

Kavli Affiliate: Jing Wang | First 5 Authors: Zhaochen Liu, Linghao Huang, Jing Wang, , | Summary: We investigate the Josephson diode effect in topological Josephson junctions. We find that while a Josephson junction in the topological phase may exhibit higher diode efficiency compared to that in the trivial phase, this behavior is not universal. […]

Charged vacancy in graphene: interplay between Landau levels and atomic collapse resonances

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Wen-Sheng Zhao, Yue Hu, R. N. Costa Filho, Francois M. Peeters | Summary: The interplay between a magnetic field and the Coulomb potential from a charged vacancy on the electron states in graphene is investigated within the tight-binding model. The Coulomb potential removes locally Landau […]
