Kavli Affiliate: Zheng Zhu | First 5 Authors: Ke Yang, Qianqian Chen, Lei Qiao, Zheng Zhu, | Summary: It remains an open question whether the two-dimensional single-band pure Hubbard model and its related pure $t$-$J$ model truly capture the superconducting order in cuprates. Recent numerical studies on this issue have raised a notable disparity in […]

Kavli Affiliate: Masahiro Nozaki | First 5 Authors: Akihiro Miyata, Masahiro Nozaki, Kotaro Tamaoka, Masataka Watanabe, | Summary: The thermodynamics and the entanglement properties of two-dimensional conformal field theories ($2$d CFTs) on curved backgrounds are studied. By means of conformal mapping we study the equivalent system on flat space governed by the deformed Hamiltonian, which […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Taojun Hu, Yi Zhou, Xiao-Hua Zhou, Satoshi Hattori, | Summary: Publication bias (PB) poses a significant threat to meta-analysis, as studies yielding notable results are more likely to be published in scientific journals. Sensitivity analysis provides a flexible method to address PB and to examine the impact […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Yidian Li, Yi Liu, Xian Du, Siqi Wu, Wenxuan Zhao | Summary: Kagome materials exhibit many novel phenomena emerging from the interplay between lattice geometry, electronic structure, and topology. A prime example is the vanadium-based kagome materials AV3Sb5 (A = K, Rb, and Cs) with superconductivity and […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yudan Wang, Yue Wang, Yi Zhou, Shaofeng Zou, | Summary: Actor-critic (AC) is a powerful method for learning an optimal policy in reinforcement learning, where the critic uses algorithms, e.g., temporal difference (TD) learning with function approximation, to evaluate the current policy and the actor updates the […]
Kavli Affiliate: Long Zhang | First 5 Authors: Jinting Li, Xi Chen, Danfang Zhang, Wenzhang Wang, Yang Zhou | Summary: High precision gyroscopes in space are important for sophisticated scientific experiments and deep space navigation. Microgravity in the space provides an ideal condition for operation of a cold atom gyroscope. To demonstrate this advantage, an […]

Due to its potential high precision, the cold atom gyroscope is expected to be the next generation of gyroscopes in space. Here, we […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Juyeon Won, Rong Zhang, Cheng Peng, Ravhi Kumar, Mebatsion S. Gebre | Summary: Recent band structure calculations have suggested the potential for band tuning in a chiral semi-conductor, Ag$_3$AuTe$_2$, to zero upon application of negative strain. In this study, we report on the synthesis of polycrystalline Ag$_3$AuTe$_2$ […]
