Quantum $z=2$ Lifshitz criticality in one-dimensional interacting fermions

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, , , , | Summary: We consider Lifshitz criticality (LC) with the dynamical critical exponent $z=2$ in one-dimensional interacting fermions with a filled Dirac Sea. We report that interactions have crucial effects on Lifshitz criticality. Single particle excitations are destabilized by interaction and decay into […]

Wet Compaction to a Blue Nugget: a Critical Phase in Galaxy Evolution

Sharon Lapiner, Avishai Dekel, Jonathan Freundlich, Omri Ginzburg, Fangzhou Jiang | Summary: [[{“value”:”We utilize high-resolution cosmological simulations to reveal that high-redshift galaxies tend to undergo a robust `wet compaction’ event when near a `golden’ stellar mass of $sim 10^{10} M_{odot}$. This is a gaseous shrinkage to a compact star-forming phase, a `blue nugget’ (BN), followed […]

The Dark Side of Using Dark Sirens to Constrain the Hubble-LemaƮtre Constant

Kavli Affiliate: Xian Chen | First 5 Authors: Liang-Gui Zhu, Xian Chen, , , | Summary: Dark sirens, i.e., gravitational-wave (GW) sources without electromagnetic counterparts, are new probes of the expansion of the universe. The efficacy of this method relies on correctly localizing the host galaxies. However, recent theoretical studies have shown that astrophysical environments […]

$g$-mode of neutron stars in pseudo-Newtonian gravity

Kavli Affiliate: Lijing Shao | First 5 Authors: Hong-Bo Li, Yong Gao, Lijing Shao, Renxin Xu, | Summary: The equation of state (EOS) of nuclear dense matter plays a crucial role in many astrophysical phenomena associated with neutron stars (NSs). Fluid oscillations are one of the most fundamental properties therein. NSs support a family of […]

CodeScore: Evaluating Code Generation by Learning Code Execution

Kavli Affiliate: Zhuo Li | First 5 Authors: Yihong Dong, Jiazheng Ding, Xue Jiang, Ge Li, Zhuo Li | Summary: A proper code evaluation metric (CEM) profoundly impacts the evolution of code generation, which is an important research field in NLP and software engineering. Prevailing match-based CEMs (e.g., BLEU, Accuracy, and CodeBLEU) suffer from two […]
