A Two-Week $IXPE$ Monitoring Campaign on Mrk 421

Kavli Affiliate: Nicola Omodei | First 5 Authors: W. Peter Maksym, Ioannis Liodakis, M. Lynne Saade, Dawoon E. Kim, Riccardo Middei | Summary: X-ray polarization is a unique new probe of the particle acceleration in astrophysical jets made possible through the Imaging X-ray Polarimetry Explorer. Here we report on the first dense X-ray polarization monitoring […]

Counting Ability of Large Language Models and Impact of Tokenization

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Juntai Cao, Chenyu You, , | Summary: Transformers, the backbone of modern large language models (LLMs), face inherent architectural limitations that impede their reasoning capabilities. Unlike recurrent networks, Transformers lack recurrent connections, confining them to constant-depth computation. This restriction places them in the complexity class […]

Observation of Quantum Criticality Class Crossover at the LaAlO$_3$/KTaO$_3$ (111) Interface

Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Long Cheng, Junkun Zha, Fei Ye, Xiaofang Zhai | Summary: In two-dimensional (2D) limit, the quantum fluctuation is significantly enhanced which could induce a quantum phase transition. Investigating the quantum criticality is an effective approach to elucidate the underlying physics of 2D superconductivity. Here we […]

Modeling the Superlattice Phase Diagram of Transition Metal Intercalation in Bilayer 2H-TaS$_2$

Kavli Affiliate: David T. Limmer | First 5 Authors: Isaac M. Craig, B. Junsuh Kim, David T. Limmer, D. Kwabena Bediako, SinĂ©ad M. Griffin | Summary: Van der Waals hosts intercalated with transition metal (TM) ions exhibit a range of magnetic properties strongly influenced by the structural order of the intercalants. However, predictive computational models […]

Resurgence of $Tbar{T}$-deformed Partition Function

Kavli Affiliate: Huajia Wang | First 5 Authors: Jie Gu, Yunfeng Jiang, Huajia Wang, , | Summary: We study non-perturbative effects of torus partition function of the $Tbar{T}$-deformed 2d CFTs by resurgence. The deformed partition function can be written as an infinite series of the deformation parameter $lambda$. We develop highly efficient methods to compute […]

The LAMOST Spectroscopic Survey of Supergiants in M31 and M33

Kavli Affiliate: Huawei Zhang | First 5 Authors: Hao Wu, Yang Huang, Huawei Zhang, Haibo Yuan, Zhiying Huo | Summary: We present systematic identifications of supergiants of M31/M33 based on massive LAMOST spectroscopic survey. Radial velocities of nearly 5000 photometrically selected M31/M33 supergiant candidates have been properly derived from the qualified spectra released in LAMOST […]

A Modulo Sampling Hardware Prototype and Reconstruction Algorithm Evaluation

Kavli Affiliate: Zheng Zhu | First 5 Authors: Jiang Zhu, Junnan Ma, Zhenlong Liu, Fengzhong Qu, Zheng Zhu | Summary: Analog-to-digital converters (ADCs) play a vital important role in any devices via manipulating analog signals in a digital manner. Given that the amplitude of the signal exceeds the dynamic range of the ADCs, clipping occurs […]

Dynamic strain sensing using Doppler-shift-immune phase-sensitive OFDR with ultra-weak reflection array and frequency-tracking

Kavli Affiliate: Li Xin Li | First 5 Authors: Qiang Yang, Weilin Xie, Congfan Wang, Bowen Li, Xin Li | Summary: In distributed fiber-optic sensing based on optical frequency domain reflectometry (OFDR), Doppler frequency shifts due to the changes of disturbances during one sweep period introduce demodulation errors that accumulate along both the distance and […]
