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 […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Ruijin Liu, Cheng Peng, Xiaoling Cui, , | Summary: We study the emergence of universal tetramer and pentamer bound states in the two-dimensional $(N+1)$ system, which consists $N$ identical heavy fermions interacting with a light atom. We show that the critical heavy-light mass ratio to support a […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Yuya Ominato, Ai Yamakage, Takeo Kato, Mamoru Matsuo, | Summary: We investigate ferromagnetic resonance (FMR) modulation in $d$-wave superconductor (SC)/ferromagnetic insulator (FI) bilayer systems theoretically. The modulation of the Gilbert damping in these systems reflects the existence of nodes in the $d$-wave SC and shows power-law decay […]
Kavli Affiliate: Xinan Zhou | First 5 Authors: Luis F. Alday, Vasco Gonçalves, Xinan Zhou, , | Summary: We present the tree-level five-point amplitude of the lowest KK mode of SYM on AdS$_5$$times$S$^3$, dual to the correlator of the flavor current multiplet in the dual 4d ${cal N}=2$ SCFT. Its color and kinematical structure is […]
