On a $mathbb{Z}_3$-valued discrete topological term in 10d heterotic string theories

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Hao Y. Zhang, , , | Summary: We show that the low-energy effective actions of two ten-dimensional supersymmetric heterotic strings are different by a $mathbb{Z}_3$-valued discrete topological term even after we turn off the $E_8times E_8$ and $Spin(32)/mathbb{Z}_2$ gauge fields. This will be demonstrated by […]

Towards a Consistent Calculation of the Lunar Response to Gravitational Waves

Kavli Affiliate: Xian Chen | First 5 Authors: Han Yan, Xian Chen, Jinhai Zhang, Fan Zhang, Mengyao Wang | Summary: The recent increasing interest in detecting gravitational waves (GWs) by lunar seismic measurement urges us to have a clear understanding of the response of the moon to passing GWs. In this paper, we clarify the […]

EIGER VI. The Correlation Function, Host Halo Mass and Duty Cycle of Luminous Quasars at $zgtrsim6$

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Anna-Christina Eilers, Ruari Mackenzie, Elia Pizzati, Jorryt Matthee, Joseph F. Hennawi | Summary: We expect luminous ($M_{1450}lesssim-26.5$) high-redshift quasars to trace the highest density peaks in our universe, and therefore to reside in proto-clusters encompassing an abundance of galaxies in close vicinity. Here, we present observations […]

Hennawi | Summary: We expect luminous ($M_{1450}lesssim-26.5$) high-redshift quasars to trace the highest density peaks in the early universe. Here, we present observations of four $zgtrsim6$ quasar fields using JWST/NIRCam in imaging and widefield slitless spectroscopy […]

Isolated nearly flat higher Chern band in monolayer transition metal trihalides

Kavli Affiliate: Jing Wang | First 5 Authors: Kejie Bao, Huan Wang, Yadong Jiang, Haosheng Xu, Jing Wang | Summary: The interplay between non-trivial topology and strong electron interaction can generate a variety of exotic quantum matter. Here we theoretically propose that monolayer transition metal trihalides MoF$_3$ and WI$_3$ have isolated nearly flat band near […]

Enhanced Monochromatic Photon Emission from Millicharged Co-Interacting Dark Matter

Kavli Affiliate: Jia Liu | First 5 Authors: Mingxuan Du, Jia Liu, Xiao-Ping Wang, Tianhao Wu, | Summary: We study a millicharged co-interacting dark matter scenario, where the primary dark matter constituent is the dark photon $A’$ and the secondary component is the fermion $chi$. In this model, $chi$ interacts with $A’$ via a $U(1)’$ […]
