Kavli Affiliate: Zheng Zhu | First 5 Authors: Meng Zeng, Zheng Zhu, Juven Wang, Yi-Zhuang You, | Summary: Lattice regularization of chiral fermions has been a long-standing problem in physics. In this work, we present the density matrix renormalization group (DMRG) simulation of the 3-4-5-0 model of (1+1)D chiral fermions with an anomaly-free chiral U(1) […]
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 […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Xinyu Wu, Yi Zhou, Jin-Kao Hao, Zhang-Hua Fu, | Summary: The Steiner tree problem, which asks for a minimum weighted tree spanning a given set of terminal vertices in a given graph, is a classic problem arising in numerous practical applications. Many algorithms about this problem emerged […]

Kavli Affiliate: Stefano Fusi | Authors: Li Ji-An, Fabio Stefanini, Marcus K Benna and Stefano Fusi | Summary: Synaptic plasticity is a complex phenomenon involving multiple biochemical processes that operate on different timescales. We recently showed that this complexity can greatly increase the memory capacity of neural networks when the variables that characterize the synaptic […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Toshiki Kurita, Masahiro Takada, , , | Summary: Rank-2 tensor fields of large-scale structure, e.g. a tensor field inferred from shapes of galaxies, open up a window to directly access 2 scalar, 2 vector and 2 tensor modes, where the scalar fields can be measured independently from […]
Kavli Affiliate: Anastasia Kiyonaga | Authors: Jacob Miller, Arielle Tambini, Anastasia Kiyonaga and Mark D’Esposito | Summary: The lateral prefrontal cortex (lPFC) is reliably active during working memory (WM) across human and animal models, but the role of lPFC in successful WM is under debate. For instance, non-human primate (NHP) electrophysiology research finds that lPFC […]
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 […]
Kavli Affiliate: Ke Wang | First 5 Authors: Hong-Li Liu, Anandmayee Tej, Tie Liu, Paul F. Goldsmith, Amelia Stutz | Summary: We present a comprehensive study of the gas kinematics associated with density structures at different spatial scales in the filamentary infrared dark cloud, G034.43+00.24 (G34). This study makes use of the H13CO+ (1-0) molecular […]
