Type-II character and anisotropic superconductivity in natural superconducting covellite

Zouyouwei Lu, Yuhang Zhang, Qiming Zhang, Xinyi Zheng et autres

Abstract We report a comprehensive investigation of the superconducting properties of the mineral superconductor covellite (CuS) using high-quality single crystals. First, we establish that CuS is an intrinsic type-II superconductor, correcting its long-standing classification as type-I. Second, a complete set of anisotropic …

MC study: The distribution features of Cherenkov lights in the EAS at a High Altitude site

Jiali Liu

Very-high-energy (VHE) gamma-rays serve as crucial probes for investigating the origin, acceleration mechanisms, propagation characteristics, and material composition of cosmic rays. The Imaging Atmospheric Cherenkov Technique (IACT) is one of the primary methods for detecting such VHE 𝛾-rays. This study aims to …

The Large Array of Imaging Atmospheric Cherenkov Telescopes (LACT): Performance and Status

Jiali Liu

The Large High Altitude Air Shower Observatory (LHAASO) has recently detected over 40 ultra-high-energy (UHE) gamma-ray sources. However, many of these sources are extended, and some are located within a small angular region ( 1°) that LHAASO cannot resolve clearly. To address …

Refined analysis and representation of atomic polarization in NMOR atomic magnetometers

Yanchao Chai, Jiali Liu, Mengnan Tian, Xin Hui Zhao et autres

The nonlinear magneto-optical rotation (NMOR) atomic magnetometer is a highly sensitive total-field device with significant applications in fundamental physics, geophysics, and biomedical monitoring. The atomic polarization, which is optically induced through resonant light pumping, plays a pivotal role in determining the sensitivity …

Free-induction-decay magnetometer based on synchronous optical pumping and RF pulse modulation

Jinghong Xu, Liwei Jiang, Jiali Liu, Yuanqiang Chen et autres

Free-induction-decay (FID) magnetometer is highly suitable for precise magnetic field sensing in unshielded environments with the benefit of exceptional accuracy and large dynamic range. The sensitivity of the FID magnetometer is directly influenced by the signal-to-noise ratio, making it critical to enhance …

Signal enhancement in single-beam free-induction-decay magnetometers by manipulation of spin polarization

Chi Fang, Jun Zhu, Yuntian Zou, Yuanqiang Chen et autres

The conventional single-beam free-induction-decay (FID) magnetometers based on an optical modulation scheme suffer from the reduction of signal in non-orthogonal magnetic field orientations, leading to worse magnetometer sensitivity. Here, we propose a scheme to enhance the signal in single-beam FID magnetometers by …

Measurement and suppression of tensor light shift for nonlinear magneto-optical rotating atomic magnetometers

Mengnan Tian, Liwei Jiang, Yanchao Chai, Jiali Liu et autres

In the NMOR atomic magnetometer , the tensor light shift is identified as a critical systemic error that affects the accuracy of magnetic resonance frequency measurements. In this paper, we present a tensor light shift measurement and suppression method based on Linear …

Nontrivial Fermi surface topology in kagome superconductor CsTi3Bi5 revealed by de Haas–van Alphen oscillation

Yuhang Zhang, Xin-Wei Yi, Zhen Zhao, Jiali Liu et autres

Abstract The kagome lattice, naturally encompassing Dirac fermions, flat bands, and van Hove singularities, tends to intertwine exotic electronic states. Revealing the characteristics of its Fermi surface will help clarify the nature of the complex quantum phenomena in kagome material. Here we …
