An emerging view of neural geometry in motor cortex supports high-performance decoding

Posted by dbos Columbia

Kavli Affiliate: Mark Churchland | Authors: Sean M. Perkins, Elom A. Amematsro, John P. Cunningham, Qi Wang and Mark M. Churchland | Summary: Decoders for brain-computer interfaces (BCIs) assume constraints on neural activity, chosen to reflect scientific beliefs while yielding tractable computations. Recent scientific advances suggest that the true constraints on neural activity, especially its […]

Analysis of Crab X-ray Polarization using Deeper IXPE Observations

Posted by dbos Stanford

Kavli Affiliate: Nicola Omodei | First 5 Authors: Josephine Wong, Tsunefumi Mizuno, Niccoló Bucciantini, Roger W. Romani, Yi-Jung Yang | Summary: We present Crab X-ray polarization measurements using IXPE data with a total exposure of 300ks, three times more than the initial 2022 discovery paper. Polarization is detected in three times more pulsar phase bins, […]

Edge Optical Effect as Probe of Chiral Topological Superconductor

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Linghao Huang, Jing Wang, , , | Summary: We study the optical effect of chiral topological superconductors in two dimensions. The linear optical response from chiral Bogoliubov edge modes in clean superconductors has in-gap resonances, which is originated from the transitions within the edge particle-hole pair bands. […]

Engineering Fractional Chern Insulators through Periodic Strain in Monolayer Graphene and Transition Metal Dichalcogenides

Posted by dbos UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Yuchen Liu, Zheng Zhu, , , | Summary: We propose the realization of interaction-driven insulators in periodically strained monolayer graphene and transition metal dichalcogenides (TMDs). Through extensive many-body exact diagonalization, we provide compelling evidence for various fractional Chern insulators (FCIs) in both strained monolayer graphene and TMDs, […]

Improved Nonlocality Certification via Bouncing between Bell Operators and Inequalities

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Weikang Li, Mengyao Hu, Ke Wang, Shibo Xu, Zhide Lu | Summary: Bell nonlocality is an intrinsic feature of quantum mechanics, which can be certified via the violation of Bell inequalities. It is therefore a fundamental question to certify Bell nonlocality from experimental data. Here, we present […]
