Nonlinear exciton polaritons in TMDs microcavities provide a versatile platform for exploring interacting many-body phenomena. To achieve an appropriate combination of strong nonlinearity with the thermal stability of the polaritons, scientists from Tsinghua University, Wuhan University and Beijing Academy of Quantum Information Sciences jointly developed the artificial mesa cavities to manipulate the nonlinear interaction and the macroscopic coherence of polaritons at ambient conditions. This work will stimulate more developments in realistic polaritonic applications based on the TMDs microcavities.

Researchers have discovered a way to tune some semiconductors to reduce the amount of energy needed to eject electrons. The approach works by placing a bilayer coating of an insulator and graphene on top of the semiconductor then applying a voltage between the semiconductor and graphene. This bilayer approach could improve the efficiency of electromechanical devices and electron accelerators.

In Journal of Applied Physics, researchers describe an acoustic metasurface that uses pingpong balls, with small holes punctured in each, as Helmholtz resonators to create inexpensive but effective low-frequency sound insulation. The coupling between two resonators led to two resonance frequencies, and more resonant frequencies meant the device was able to absorb more sound. At the success of two coupled resonators, the researchers added more, until their device resembled a square sheet of punctured pingpong balls, multiplying the number of resonant frequencies that could be absorbed.

Within a neighboring dwarf galaxy known as the Small Magellanic Cloud (SMC) lies a dramatic region of star birth – NGC 346, shown here. As the brightest and largest star-forming region in the SMC, it has been studied intensely by a variety of telescopes. NASA’s Hubble Space Telescope showed a visible-light view filled with thousands of stars. More recently, NASA’s James Webb Space Telescope offered a near-infrared vista highlighting both cool and warm dust. Now, Webb has turned its mid-infrared gaze to NGC 346, revealing streamers of gas and dust studded with bright patches filled with young protostars.

When a muon binds with a deuteron, it forms a system with two neutrons in a process analogous to proton-proton fusion. Nuclear theorists examined this muon capture process to quantify theoretical uncertainty relevant for comparison with experimental data and to test predictions involving proton-proton fusion. The study supports ongoing efforts to enhance the accuracy of muon capture measurements and to apply the same theoretical framework to other processes.
