Research Progress on Thermal Conductivity of Ordered Crystals

The CSNS data analysis group has successfully investigated the structure and phonon dynamics of the thermoelectric material CsAg5Te3, explaining the mechanism behind the anomalously low thermal conductivity of this well-ordered crystal. This researchwas published in National Science Review under the title "Strong low-energy rattling modes enabled liquid-like ultralow thermal conductivity in a well-ordered solid."

LHAASO Discovers Ultra-high-energy Gamma-ray Radiation from the Tail of Bow-shock Pulsar Wind Nebula

The Large High Altitude Air Shower Observatory (LHAASO), a major national science and technology infrastructure project in China, has achieved a groundbreaking discovery in gamma-ray astronomy. Using over 1,200 days of observational data, LHAASO detected ultra-high-energy gamma-ray radiation from the tail region of the bow-shock pulsar wind nebula (BSPWN) associated with the pulsar PSR J1740+1000 with a significance of 17 standard deviations. This marks the first observation of gamma-ray radiation from the tail of a bow-shock pulsar wind nebula, challenging existing theories on particle transport mechanisms and suggesting the presence of a robust particle acceleration process in this region. The findings were published on February 7, 2025, in the academic journal The Innovation.

Multi-stage Clustering Algorithm Enabling Intelligent Nano-ARPES Experiment

Recently, the HEPS (High Energy Photon Source) Software for experimental control System and Nano-ARPES (angle-resolved photoemission spectroscopy) beamline have made significant progress in automatically categorizing the ARPES spatial mapping dataset using unsupervised clustering method. Researchers have developed a multi-stage clustering algorithm (MSCA) that achieves the clustering analysis both in real space and momentum space in spatially resolved ARPES dataset and successfully distinguishes the monolayer and multilayer of MoS2 and whether it is on different substrates (BN or Au).
