Kavli Affiliate: Chris Xu | First 5 Authors: Chris Xu, , , , | Summary: We prove nonhalting of the Turing machine dubbed "Skelet #17", known to be one of the toughest 5-state, 2-symbol Turing machines to analyze. Combined with the efforts of The Busy Beaver Challenge, we are therefore able to show that BB(5), […]
Kavli Affiliate: Dan Luo | First 5 Authors: Chaoran Zhang, Lixin Zou, Dan Luo, Min Tang, Xiangyang Luo | Summary: In recent years, Large Language Models (LLMs) have demonstrated remarkable capabilities across a wide array of text-centric tasks. However, their `large’ scale introduces significant computational and storage challenges, particularly in managing the key-value states of […]
Kavli Affiliate: Jie Shan | First 5 Authors: Huiying Cui, Qianying Hu, Xuan Zhao, Liguo Ma, Feng Jin | Summary: The study of exciton-polarons has offered profound insights into the many-body interactions between bosonic excitations and their immersed Fermi sea within layered heterostructures. However, little is known about the properties of exciton polarons with interlayer […]
Kavli Affiliate: Brad J. Ramshaw | First 5 Authors: Fabian Jerzembeck, You-Sheng Li, Grgur Palle, Zhenhai Hu, Mehdi Biderang | Summary: There is considerable evidence that the superconductivity of Sr2RuO4 has two components. Among this evidence is a jump in the shear elastic modulus $c_{66}$ at the critical temperature $T_c$, observed in ultrasound measurements. Such […]

Kavli Affiliate: Jie Shan | First 5 Authors: Patrick Knüppel, Jiacheng Zhu, Yiyu Xia, Zhengchao Xia, Zhongdong Han | Summary: Twisted bilayers of transition metal dichalcogenide (TMD) semiconductors have emerged as a highly tunable system for the studies of correlated and topological states of matter, such as superconductivity, ferromagnetism, correlated insulators, and topological and Chern […]
Kavli Affiliate: Jie Shan | First 5 Authors: Patrick Knüppel, Jiacheng Zhu, Yiyu Xia, Zhengchao Xia, Zhongdong Han | Summary: Twisted bilayers of transition metal dichalcogenide semiconductors have enabled the discovery of superconductivity, ferromagnetism, correlated insulators and a series of new topological phases of matter. However, the connection between these electronic phases and the underlying […]
Kavli Affiliate: Jeffrey Moses | First 5 Authors: Dylan Heberle, Noah Flemens, Connor Davis, Philippe Lassonde, Adrien Leblanc | Summary: Dispersion management of few-cycle pulses is crucial for ultrafast optics and photonics. Often, nontrivial dispersion is compensated using complex optical systems or minimized through careful design of waveguides. Here, we present dispersion-managed adiabatic frequency conversion […]
Kavli Affiliate: Jie Shan | First 5 Authors: Yiyu Xia, Zhongdong Han, Kenji Watanabe, Takashi Taniguchi, Jie Shan | Summary: Moir’e materials have enabled the realization of flat electron bands and quantum phases that are driven by strong correlations associated with flat bands. Superconductivity has been observed, but solely, in graphene moir’e materials. The absence […]
Kavli Affiliate: Zhiting Tian | First 5 Authors: Jaeyun Moon, Zhiting Tian, , , | Summary: Thermal transport properties of amorphous carbon has attracted increasing attention due to its extreme thermal properties: It has been reported to have among the highest thermal conductivity for bulk amorphous solids up to $sim$ 37 Wmtextsuperscript{-1}Ktextsuperscript{-1}, comparable to crystalline […]
