Preparation and observation of anomalous counterpropagating edge states in a periodically driven optical Raman lattice

Kavli Affiliate: Long Zhang | First 5 Authors: Hongting Hou, Long Zhang, , , | Summary: Motivated by the recent observation of real-space edge modes with ultracold atoms [Braun et al., Nat. Phys. 20, 1306 (2024)], we investigate the preparation and detection of anomalous counterpropagating edge states — a defining feature of the anomalous Floquet […]

D-commuting SYK model: building quantum chaos from integrable blocks

Kavli Affiliate: Cheng Peng | First 5 Authors: Ping Gao, Han Lin, Cheng Peng, , | Summary: We construct a new family of quantum chaotic models by combining multiple copies of integrable commuting SYK models. As each copy of the commuting SYK model does not commute with others, this construction breaks the integrability of each […]

Sobolev Versus Homogeneous Sobolev Extension

Kavli Affiliate: Zheng Zhu | First 5 Authors: Pekka Koskela, Riddhi Mishra, Zheng Zhu, , | Summary: In this paper, we study the relationship between Sobolev extension domains and homogeneous Sobolev extension domains. Precisely, we obtain the following results. 1- Let $1leq qleq pleq infty$. Then a bounded $(L^{1, p}, L^{1, q})$-extension domain is also […]

SPARS3R: Semantic Prior Alignment and Regularization for Sparse 3D Reconstruction

Kavli Affiliate: Cheng Peng | First 5 Authors: Yutao Tang, Yuxiang Guo, Deming Li, Cheng Peng, | Summary: Recent efforts in Gaussian-Splat-based Novel View Synthesis can achieve photorealistic rendering; however, such capability is limited in sparse-view scenarios due to sparse initialization and over-fitting floaters. Recent progress in depth estimation and alignment can provide dense point […]

Diffusive dynamics of charge regulated macro-ion solutions

Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Bin Zheng, Shigeyuki Komura, David Andelman, Rudolf Podgornik, | Summary: Onsager’s variational principle is generalized to address the diffusive dynamics of an electrolyte solution composed of charge-regulated macro-ions and counterions. The free energy entering the Rayleighian corresponds to the Poisson-Boltzmann theory augmented by the charge-regulation mechanism. The […]

ProteinWeaver: A Divide-and-Assembly Approach for Protein Backbone Design

Kavli Affiliate: Yi Zhou | First 5 Authors: Yiming Ma, Fei Ye, Yi Zhou, Zaixiang Zheng, Dongyu Xue | Summary: Nature creates diverse proteins through a ‘divide and assembly’ strategy. Inspired by this idea, we introduce ProteinWeaver, a two-stage framework for protein backbone design. Our method first generates individual protein domains and then employs an […]
