Kavli Affiliate: Zheng Zhu | First 5 Authors: Qianqian Chen, Shuai A. Chen, Zheng Zhu, , | Summary: The recent discovery of persistent revivals in the Rydberg-atom quantum simulator has revealed a weakly ergodicity-breaking mechanism dubbed quantum many-body scars, which are a set of nonthermal states embedded in otherwise thermal spectra. Until now, such a […]
Kavli Affiliate: Xinan Zhou | First 5 Authors: Agnese Bissi, Aninda Sinha, Xinan Zhou, , | Summary: This review aims to offer a pedagogical introduction to the analytic conformal bootstrap program via a journey through selected topics. We review analytic methods which include the large spin perturbation theory, Mellin space methods and the Lorentzian inversion […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Shuai A. Chen, Qianqian Chen, Zheng Zhu, , | Summary: Recent realization of well-controlled quantum simulators of the triangular-lattice Fermi-Hubbard model, including the triangular optical lattices loaded with ultracold Fermions and the heterostructures of the transition-metal dichalcogenides, as well as the more advanced techniques to probe them, […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Hiroyuki Tajima, Daigo Oue, Mamoru Matsuo, Takeo Kato, | Summary: We theoretically propose a method to identify the tunneling current carrier in interacting fermions from nonequilibrium noise in the Bardeen-Cooper-Schrieffer to Bose–Einstein condensate crossover. The noise-to-current ratio, the Fano factor, can be a crucial probe for the […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Ruijin Liu, Cheng Peng, Xiaoling Cui, , | Summary: Identifying few-body correlations is an efficient tool to solve complex many-body problems. The polarons, interpolating between few- and many-body systems, serve as an ideal platform to achieve the goal. In this work, we reveal various crystalline few-body correlations […]

Kavli Affiliate: Yi Zhou | First 5 Authors: Quang Minh Nguyen, Hoang H. Nguyen, Yi Zhou, Lam M. Nguyen, | Summary: We study the Unbalanced Optimal Transport (UOT) between two measures of possibly different masses with at most $n$ components, where marginal constraints of the standard Optimal Transport (OT) are relaxed via Kullback-Leibler divergence with […]

Kavli Affiliate: Zheng Zhu | First 5 Authors: Xiangyu Peng, Kai Wang, Zheng Zhu, Mang Wang, Yang You | Summary: Recent self-supervised contrastive learning methods greatly benefit from the Siamese structure that aims at minimizing distances between positive pairs. For high performance Siamese representation learning, one of the keys is to design good contrastive pairs. […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Mingkun Li, Shupeng Cheng, Peng Xu, Xiatian Zhu, Chun-Guang Li | Summary: We investigate unsupervised person re-identification (Re-ID) with clothes change, a new challenging problem with more practical usability and scalability to real-world deployment. Most existing re-id methods artificially assume the clothes of every single person to […]
