Spectroscopy Signatures of Electron Correlations in a Trilayer Graphene/hBN Moiré Superlattice

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Jixiang Yang, Guorui Chen, Tianyi Han, Qihang Zhang, Ya-Hui Zhang | Summary: ABC-stacked trilayer graphene/hBN moir’e superlattice (TLG/hBN) has emerged as a playground for correlated electron physics. We report spectroscopy measurements of dual-gated TLG/hBN using Fourier transformed infrared photocurrent spectroscopy. We observed a strong optical transition between […]

$Rheomergy$: Collective behavior mediated by active flow-based recruitment

Posted by klaurent Harvard

Kavli Affiliate: L. Mahadevan | First 5 Authors: S Ganga Prasath, L Mahadevan, , , | Summary: The physics of signal propagation in a collection of organisms that communicate with each other both enables and limits how active excitations at the individual level reach, recruit and lead to collective patterning. Inspired by the patterns in […]

Exploring Edge Disentanglement for Node Classification

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Tianxiang Zhao, Xiang Zhang, Suhang Wang, , | Summary: Edges in real-world graphs are typically formed by a variety of factors and carry diverse relation semantics. For example, connections in a social network could indicate friendship, being colleagues, or living in the same neighborhood. However, these latent […]

DialMed: A Dataset for Dialogue-based Medication Recommendation

Posted by Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Zhenfeng He, Yuqiang Han, Zhenqiu Ouyang, Wei Gao, Hongxu Chen | Summary: Medication recommendation is a crucial task for intelligent healthcare systems. Previous studies mainly recommend medications with electronic health records(EHRs). However, some details of interactions between doctors and patients may be ignored in EHRs, which are […]

Performance evaluation of baseline-dependent averaging based onfull-scale SKA1-LOW simulation

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Qing-Wen Deng, Feng Wang, Hui Deng, Ying Mei, Jing Li | Summary: The Square Kilometre Array (SKA) is the largest radio interferometer under construction in the world. Its immense amount of visibility data poses a considerable challenge to the subsequent processing by the science data processor (SDP). […]

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

Posted by klaurent Berkeley

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 […]

Optimizing the topological properties of stacking semiconductor-ferromagnet-superconductor heterostructures

Posted by klaurent Delft

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 […]

Integrated optical-readout of a high-Q mechanical out-of-plane mode

Posted by klaurent Delft

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 […]
