How Does One Non-Radial Solar Eruption Produce Two Coronal Mass Ejections on the Sun?[Aug 23, 2019]

An observation conducted by solar physicists from Yunnan Observatories and Yunnan Normal University clearly indicated that two simultaneous radial propagating CMEs were dynamically associated with the eruption of a blowout jet that was driven by the eruption of a miniature filament.

Control Magnetization of a van der Waals Ferromagnet by Current[Aug 24, 2019]

A joint research team from the Chinese Academy of Sciences made progress in electrically controlling the magnetization of van der Waals (vdW) magnets. They developed a convenient method combining the ferromagnetism of vdW materials with the spin Hall effect of an adjacent heavy metal layer.

Scientists Demonstrate Quantum Behavior of Relativistic Electrons in Strong Laser Field[Aug 22, 2019]

A research team from the Shanghai Institute of Optics and Fine Mechanics proposed a cross-collision scheme to demonstrate the quantum behavior of high energy electrons. The study mainly focused to identify the QED feature for relativistic electrons moving in extremely strong laser fields that can be captured in possible experiments.
