Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Yoann L. Launay, Gerasimos I. Rigopoulos, E. P. S. Shellard, , | Summary: We provide a formulation of Stochastic Inflation in full general relativity that goes beyond the slow-roll and separate universe approximations. We show how gauge invariant Langevin source terms can be obtained for […]
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: Misao Sasaki | First 5 Authors: Guillem Domènech, Misao Sasaki, , , | Summary: It is possible that primordial black holes consitute (or consituted) a significant fraction of the energy budget of our universe. Terrestrial gravitational wave detectors offer the opportunity to test the existence of primordial black holes in two different mass […]
Kavli Affiliate: Sara Seager | First 5 Authors: William Bains, Janusz J. Petkowski, Sara Seager, , | Summary: Life is a complex, dynamic chemical system that requires a dense fluid solvent in which to take place. A common assumption is that the most likely solvent for life is liquid water, and some researchers argue that […]
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: John Silverman | First 5 Authors: Angelo George, Ivana Damjanov, Marcin Sawicki, Stéphane Arnouts, Guillaume Desprez | Summary: We analyze the size evolution of $16000$ star-forming galaxies (SFGs) and $5000$ quiescent galaxies (QGs) with mass $M_*>10^{9.5}M_odot$ at $0.1<z<0.9$ from the COSMOS field using deep CLAUDS+HSC imaging in two rest-frame wavelengths, $3000$r{A} (UV light) […]
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, […]
