A Worst-Case Approximate Analysis of Peak Age-of-Information Via Robust Queueing Approach
Zhongdong Liu, Yu Sang, Bin Li +1
A new timeliness metric, called Age-of-Information (AoI), has recently attracted a lot of research interests for real-time applications with information updates. It has been extens…
Reconstruction of dark energy using DESI DR2
Xue Zhang, Yin-Hao Xu, Yu Sang
Using a model-independent Gaussian process (GP) method to reconstruct the dimensionless luminosity distance and its derivatives, we derive the evolution of the dimensionless Hu…
The temporally evolving energy and waiting time statistics of two repeating fast radio bursts
Yu Sang, Hai-Nan Lin
Based on two very large samples of repeating fast radio bursts (FRBs), i.e. FRB 20121102A and FRB 20201124A observed by the FAST telescope, we study the statistical properties of e…
Oscillons during Dirac-Born-Infeld Preheating
Yu Sang, Qing-Guo Huang
Oscillons are long-lived, localized, oscillating nonlinear excitations of a real scalar field which can be abundantly produced during preheating after inflation. We give the first…
Cosmological Forecasts from the Baryon Acoustic Oscillations in 21cm Intensity Mapping
Benjamin Ostergaard, André Alencar da Costa, Yu Sang
In this work we use a template method to extract the scale associated with the Baryon Acoustic Oscillation (BAO) signal in 21cm neutral hydrogen intensity maps. We then forecast th…
Entanglement transfer between giant atoms in waveguide-QED systems
Jie Liu, Zhi-Qiang Liu, Yu Sang +1
We investigate the entanglement transfer between giant atoms in waveguide-QED systems. The system consists of two pairs of two-level giant atoms, and , each independently…
