In September 2023, Associate Professor Guorui Chen's team at the Key Laboratory of Artificial Structures and Quantum Regulation of the Ministry of Education, Shanghai Jiao Tong University, collaborated with Jeil Jung's team at Seoul National University, Korea, to publish an article in Nature titled 'Spontaneous broken-symmetry insulator and metals in tetralayer rhombohedral graphene'. The article demonstrates that crystalline multilayer graphene is an ideal platform for studying various symmetry breaking driven by Coulomb interactions.
In 2022, Prof. Xiaomu Wang and Prof. Yi Shi from Nanjing University published an article in Nature Communications titled 'Quantum Criticality of Excitonic Mott Metal-Insulator Transitions in Black Phosphorus.' The article reports on the spectroscopy and transport phenomena of excitonic Mott metal-insulator transitions in black phosphorus. Photoexcitation continuously modulates the interactions between electron-hole pairs. Fourier transform photocurrent spectroscopy was used to measure the integrated phase diagrams of the electron-hole states at different temperatures and electron-hole pair density parameter spaces as a probe.

The MRS Fall Meeting & Exposition 2023 is the world's premier international scientific meeting for materials research, showcasing interdisciplinary research by scientists from around the world in both fundamental and applied fields.
Keywords: NV color center, Lock-in amplifier, Quantum sensing
Sine Scientific Instrument's dual-channel lock-in amplifier, the OE1022D, is being used in four groups at the University of Wisconsin's School of Electrical and Computer Engineering and the School of Materials Science and Engineering, primarily for research work in two-dimensional/quantum materials characterization, nanodevices, and terahertz.
Recently, in the 2023 "National Key R&D Program Project" progress exchange meeting, Sine Scientific Instrument team's chief technical advisor, Associate Professor Wang Zixin of Sun Yat-sen University, as the project leader reported the progress of the "National Key R&D Program" project, "Research and Development of Precision and Large-Bandwidth Lock-in Amplifier and Application". "The project has realized the high precision phase-locked amplification technology with more than 100M bandwidth. The industry experts attending the meeting highly praised the current team's achievements in phase-locked amplifiers.
OE1022D has been used in SQUID scanning microscope measurements by The Witzman Institute of Israel. Witzman Institute has purchased more than 10 scion scientific Instruments lock-In amplifiers. This type of phase-locked amplifier has been approved by Witzman Institute of Israel, as detailed in the user comments below.
The OE1022D Lock-In Amplifier designed by SSI obtained an order from the Weizman Institute of Science in Israel. The team was satisfied with the performance of the instrument and indicated that they would have further cooperation with SSI in the future.
