Symmetric Mass Generation in the 1+1 Dimensional Chiral Fermion 3-4-5-0 Model

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) […]

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

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 […]

Face familiarity detection with complex synapses

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 […]

Analysis method for 3D power spectrum of projected tensor field with fast estimator and window convolution modelling: an application to intrinsic alignments

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 […]

Long-term learning transforms prefrontal cortex representations during working memory

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 […]
