Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Xiaogang Liu, , , | Summary: In this paper, we study the existence of perfect state transfer and pretty good state transfer in vertex complemented coronas. We prove that perfect state transfer in vertex complemented coronas is extremely rare. In contrast, we give sufficient conditions […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Razieh Emami, Lars Hernquist, Mark Vogelsberger, Xuejian Shen, Joshua S. Speagle | Summary: We analyze the velocity anisotropy of stars in real and energy space for a sample of Milky Way-like galaxies in the TNG50 simulation. We employ different selection criteria, including spatial, kinematic and metallicity cuts, […]
Kavli Affiliate: Cornelia Bargmann | Authors: Du Cheng, James Lee, Maximillian Brown, Margaret S. Ebert, Masahiro Tomioka, Yuichi Iino and Cornelia I Bargmann | Summary: Information flow through neural circuits is continuously modified by context-dependent learning. In the nematode Caenorhabditis elegans, pairing specific odors with food deprivation results in aversion to the odor. Here we […]
Kavli Affiliate: D. B. Macfarlane | First 5 Authors: SuperCDMS Collaboration, M. F. Albakry, I. Alkhatib, D. W. P. Amaral, T. Aralis | Summary: Two photo-neutron sources, $^{88}$Y$^{9}$Be and $^{124}$Sb$^{9}$Be, have been used to investigate the ionization yield of nuclear recoils in the CDMSlite germanium detectors by the SuperCDMS collaboration. This work evaluates the yield […]
Kavli Affiliate: Jing Wang | First 5 Authors: Si-Yue Yu, Dewang Xu, Luis C. Ho, Jing Wang, Wei-Bo Kao | Summary: Spiral-driven instabilities may drive gas inflow to enhance central star formation in disk galaxies. We investigate this hypothesis using the Sloan Digital Sky Survey (SDSS) in a sample of 2779 nearby unbarred star-forming main-sequence […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: Chun-Xiao Liu, Michael Wimmer, , , | Summary: We study the electronic properties of a planar semiconductor-superconductor heterostructure, in which a thin ferromagnetic insulator layer lies in between and acts as a spin filtering barrier. We find that in such a system one can simultaneously enhance the […]
Kavli Affiliate: Simon Groblacher | First 5 Authors: Jingkun Guo, Simon Gröblacher, , , | Summary: The rapid development of high-Q macroscopic mechanical resonators has enabled great advances in optomechanics. Further improvements could allow for quantum-limited or quantum-enhanced applications at ambient temperature. Some of the remaining challenges include the integration of high-Q structures on a […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Zhicheng He, Guilin Liu, Tinggui Wang, Guobin Mou, Richard Green | Summary: Quasar outflows may play a crucial role in regulating the host galaxy, although the spatial scale of quasar outflows remain a major enigma, with their acceleration mechanism poorly understood. The kinematic information of outflow […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Zhenhai Yu1, Xuejiao Chen, Wei Xia, Ningning Wang, Xiaodong Lv | Summary: The rich nontrivial topological phases rooted in the interplay between magnetism and topology in the layered antiferromagnet EuCd2As2 have captured vast attention, especially the ideal Weyl semimetal state realized in the spin-polarized ferromagnetic (FM) […]
Kavli Affiliate: W. L. Kimmy Wu | First 5 Authors: Dominic Beck, Ari Cukierman, W. L. Kimmy Wu, , | Summary: We investigate simulation-based bandpower covariance matrices commonly used in cosmological parameter inferences such as the estimation of the tensor-to-scalar ratio~$r$. We find that upper limits on $r$ can be biased low. The underestimation of […]
