Kavli Affiliate: Jie Shan | First 5 Authors: Patrick Knüppel, Jiacheng Zhu, Yiyu Xia, Zhengchao Xia, Zhongdong Han | Summary: Twisted bilayers of transition metal dichalcogenide semiconductors have enabled the discovery of superconductivity, ferromagnetism, correlated insulators and a series of new topological phases of matter. However, the connection between these electronic phases and the underlying […]
Kavli Affiliate: Jie Shan | First 5 Authors: Patrick Knüppel, Jiacheng Zhu, Yiyu Xia, Zhengchao Xia, Zhongdong Han | Summary: Twisted bilayers of transition metal dichalcogenide (TMD) semiconductors have emerged as a highly tunable system for the studies of correlated and topological states of matter, such as superconductivity, ferromagnetism, correlated insulators, and topological and Chern […]
Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Tamara Evstafyeva, Ulrich Sperhake, Isobel Romero-Shaw, Michalis Agathos, | Summary: Gravitational-wave signals detected to date are commonly interpreted under the paradigm that they originate from pairs of black holes or neutron stars. Here, we explore the alternative scenario of boson-star signals being present in the data stream. […]

Kavli Affiliate: Mohammad Mirhosseini | First 5 Authors: Han Zhao, William David Chen, Abhishek Kejriwal, Mohammad Mirhosseini, | Summary: A quantum interface between microwave and optical photons is essential for entangling remote superconducting quantum processors. To preserve fragile quantum states, a transducer must operate efficiently while generating less than one photon of noise referred to […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Ian U. Roederer, Timothy C. Beers, Kohei Hattori, Vinicius M. Placco, Terese T. Hansen | Summary: We present stellar parameters and chemical abundances of 47 elements detected in the bright (V = 11.63) very metal-poor ([Fe/H] = -2.20 +- 0.12) star 2MASS J22132050-5137385. We observed this star […]
Kavli Affiliate: Philip J. Marshall | First 5 Authors: Kenneth C. Wong, Frédéric Dux, Anowar J. Shajib, Sherry H. Suyu, Martin Millon | Summary: Time-delay cosmography is a powerful technique to constrain cosmological parameters, particularly the Hubble constant ($H_{0}$). The TDCOSMO collaboration is performing an ongoing analysis of lensed quasars to constrain cosmology using this […]

Kavli Affiliate: Yingjie Peng | First 5 Authors: Caro Derkenne, Richard M. McDermid, Francesco D’Eugenio, Caroline Foster, Aman Khalid | Summary: We use the `Middle Ages Galaxy Properties with Integral field spectroscopy’ (MAGPI) survey to investigate whether galaxies have evolved in the distribution of their stellar angular momentum in the past 3-4 Gyr, as probed […]
Kavli Affiliate: Wei Gao | First 5 Authors: Ruichao Yang, Wei Gao, Jing Ma, Hongzhan Lin, Bo Wang | Summary: Learning multi-task models for jointly detecting stance and verifying rumors poses challenges due to the need for training data of stance at post level and rumor veracity at claim level, which are difficult to obtain.
