Evidence for a spinon Kondo effect in cobalt atoms on single-layer 1T-TaSe$_2$

Kavli Affiliate: Feng Wang | First 5 Authors: Yi Chen, Wen-Yu He, Wei Ruan, Jinwoong Hwang, Shujie Tang | Summary: Quantum spin liquids (QSLs) are highly entangled, disordered magnetic states that arise in frustrated Mott insulators and host exotic fractional excitations such as spinons and chargons. Despite being charge insulators some QSLs are predicted to […]

Insulin/IGF Signaling Regulates Presynaptic Glutamate Release in Aversive Olfactory Learning

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 […]

Ionization yield measurement in a germanium CDMSlite detector using photo-neutron sources

Kavli Affiliate: Paul Brink | 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 for nuclear recoil energies between 1 keV and 7 keV at a temperature of $sim$ 50 mK. We use […]

Strong spiral arms drive secular growth of pseudo bulges in disk galaxies

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 […]

Evidence for quasar fast outflows being accelerated at the scale of tens of parsecs

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 […]

Bias on Tensor-to-Scalar Ratio Inference With Estimated Covariance Matrices

Kavli Affiliate: 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 by tens of percent. The underestimation of the upper limit is most severe when the number […]

Proposal for asymmetric photoemission and tunneling spectroscopies in quantum simulators of the triangular-lattice Fermi-Hubbard model

Kavli Affiliate: Zheng Zhu | First 5 Authors: Shuai A. Chen, Qianqian Chen, Zheng Zhu, , | Summary: Recent realization of well-controlled quantum simulators of the triangular-lattice Fermi-Hubbard model, including the triangular optical lattices loaded with ultracold Fermions and the heterostructures of the transition-metal dichalcogenides, as well as the more advanced techniques to probe them, […]
