Kavli Affiliate: Huajia Wang | First 5 Authors: Liangyu Chen, Anatoly Dymarsky, Jia Tian, Huajia Wang, | Summary: The eigenstate thermalization hypothesis (ETH) in chaotic two dimensional CFTs is subtle due to infinitely many conserved KdV charges. Previous works have demonstrated that primary CFT eigenstates have flat entanglement spectrum, which is very different from the […]
Kavli Affiliate: Huajia Wang | First 5 Authors: Liangyu Chen, Anatoly Dymarsky, Jia Tian, Huajia Wang, | Summary: We study subsystem entropy in 2d CFTs, for subsystems constituting a finite fraction of the full system. We focus on the extensive contribution, which scales linearly with the subsystem size in the thermodynamic limit. We employ the […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Weichen Dai, Yezeng Chen, Zijie Dai, Zhijie Huang, Yubo Liu | Summary: Artificial intelligence is gradually demonstrating its immense potential, and increasing attention is being given to how AI can be harnessed to advance scientific research. In this vision paper, we present our perspectives on how AI […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Xin Hu, Yuya Ominato, Mamoru Matsuo, , | Summary: We develop a microscopic theory of the spin Seebeck effect (SSE) at the interface of a bilayer system of a ferromagnetic insulator and graphene. We compare the tunneling spin current at the interface due to the SSE and […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Masaki Yama, Mamoru Matsuo, Takeo Kato, , | Summary: We theoretically investigate spin transport in a junction system composed of a ferromagnetic insulator (FI) and a two-dimensional electron gas (2DEG) with both Rashba and Dresselhaus spin-orbit interactions. We briefly present our findings on spin pumping into the […]

Kavli Affiliate: Gang Su | First 5 Authors: Jin-Wei Dong, Yu-Han Lin, Ruiqing Fu, Gang Su, Ziqiang Wang | Summary: Loop current order has been suggested as a promising candidate for the spontaneous time-reversal symmetry breaking $2a_0 times 2a_0$ charge density wave (CDW) revealed in vanadium-based kagom’e metals avs ($A$ = K, Rb, Cs) near […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Yiqian Chen, Lang Cheng, Peng Wang, Haitang Yang, | Summary: This study investigates polarized images of an equatorial synchrotron-emitting ring surrounding hairy black holes within the Einstein-Maxwell-scalar theory. Our analysis demonstrates qualitative similarities between the polarization patterns of hairy black holes and Schwarzschild black holes. However, due […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Jintian Zhang, Cheng Peng, Mengshu Sun, Xiang Chen, Lei Liang | Summary: Despite the recent advancements in Large Language Models (LLMs), which have significantly enhanced the generative capabilities for various NLP tasks, LLMs still face limitations in directly handling retrieval tasks. However, many practical applications demand the […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Jie Zhu, Yiwei Qiu, Yangjun Zeng, Yi Zhou, Shi Chen | Summary: Utility-scale off-grid renewable power-to-hydrogen systems (OReP2HSs) typically include photovoltaic plants, wind turbines, electrolyzers (ELs), and energy storage systems. As an island system, OReP2HS requires at least one component, generally the battery energy storage system (BESS), […]
