Semiconductor-superconductor hybrids can host intriguing phases of matter such as Majorana zero modes. One example is planar Josephson junctions (JJs) based on a two dimensional electron gas (2DEG) coupled to a superconductor. Compared to nanowire proposals, the advantage of this 2D approach is th…

On April 19, 2024, the opening ceremony of the National Conference on Low Temperature Physics was held in Ningbo, Zhejiang Province, at which the winners of the 7th Sir Martin Wood Science Prize for…
Recently, a research team led by Prof. Yong-Chun Liu at Department of Physics, Tsinghua University, discovers that the collision of thermal atoms can induce high-performance optical nonreciprocity. …
The critical magnetic field of a superconductor defines the field that can turn the superconducting state to the normal state. It is one of the basic properties of superconductivity and an important…
Recently, a group led by Associate Professor Yong-Chun Liu from Tsinghua University proposed an intracavity-squeezed optomechanical cooling method to break the quantum backaction limit for ground-st…
