Kavli Affiliate: Ke Wang | First 5 Authors: Zehang Bao, Shibo Xu, Zixuan Song, Ke Wang, Liang Xiang | Summary: Greenberger-Horne-Zeilinger (GHZ) states, as maximally entangled Schr"{o}dinger cat states, play vital roles in the foundations of quantum physics and technology, but creating and preserving these fragile states pose tremendous challenges. Discrete time crystals (DTCs), originally […]

Kavli Affiliate: Jing Wang | First 5 Authors: Fu Feng, Jing Wang, Xin Geng, , | Summary: The pre-training paradigm fine-tunes the models trained on large-scale datasets to downstream tasks with enhanced performance. It transfers all knowledge to downstream tasks without discriminating which part is necessary or unnecessary, which may lead to negative transfer. In […]

Kavli Affiliate: Lijing Shao | First 5 Authors: Zhan-Feng Mai, Rui Xu, Dicong Liang, Lijing Shao, | Summary: Spherical black-hole (BH) solutions have been found in the bumblebee gravity where a vector field nonminimally couples to the Ricci tensor. We study dynamic (in)stability associated with the gravitational and vector perturbations of odd parity against these […]

Kavli Affiliate: Zhuo Li | First 5 Authors: Guang-Xuan Lan, Ye Li, Zhuo Li, , | Summary: We present a method to estimate the detection expectations of host galaxies of long gamma-ray bursts (LGRBs) in the {it grizJHKL} bands. It is found that given the same limiting magnitude $m_{grizJHKL,rm lim}$ in each band, the {it […]

Kavli Affiliate: Huawei Zhang | First 5 Authors: Ruifeng Shi, Yang Huang, Xinyi Li, Huawei Zhang, | Summary: Deriving atmospheric parameters of a large sample of stars is of vital importance to understand the formation and evolution of the Milky Way. Photometric surveys, especially those with near-ultraviolet filters, can offer accurate measurements of stellar parameters, […]

Kavli Affiliate: Linhua Jiang | First 5 Authors: Shuqi Fu, Linhua Jiang, Yuanhang Ning, Weiyang Liu, Zhiwei Pan | Summary: We present a study of a sample of 45 spectroscopically confirmed, UV luminous galaxies at $zsim 6$. They were selected as bright Lyman-break galaxies (LBGs) using deep multi-band optical images in more than 2 deg$^2$ […]

Kavli Affiliate: Huawei Zhang | First 5 Authors: Han Lin, Xiaofeng Wang, Jujia Zhang, Danfeng Xiang, Tianmeng Zhang | Summary: We present 206 unpublished optical spectra of 104 type II supernovae obtained by the Xinglong 2.16m telescope and Lijiang 2.4m telescope during the period from 2011 to 2018, spanning the phases from about 1 to […]

Kavli Affiliate: Huawei Zhang | First 5 Authors: Huiling Chen, Yang Huang, Wei Zhu, Timothy C. Beers, Renjing Xie | Summary: A recent study by Hon et al. reported that a close-in planet around the red clump star, 8 UMi, should have been engulfed during the expansion phase of the stellar evolution. They explained the […]
