Manipulating nonlinear exciton polaritons in an atomically-thin semiconductor with artificial potential landscapes
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.
Spin-orbit Optical Rabi oscillations
Rabi oscillation is an important wave phenomenon in different disciplines. The wave states in the Rabi oscillations have been revealed as spin waves and orbital waves, while a Rabi wave state merging the spin and orbital angular momentum has remained elusive.

Researchers Develop a Novel Method to Study Nuclear Reactions on Short-Lived Isotopes Involved in Explosions of Stars
The nuclear reactions that power stellar explosions involve short-lived nuclei that are hard to study in the laboratory. Researchers used a combination of methods to measure a reaction where a neutron from a deuterium target is exchanged with a proton from a radioactive projectile, a reaction equivalent to a process in exploding stars.

Quantum Dots: FAMU-FSU College of Engineering Professor Collaborated on Early Work That Led to Nobel Prize in Chemistry
By: Tisha Keller | Published: October 11, 2023 | 2:41 pm | SHARE: The 2023 Nobel Prize in Chemistry was recently awarded to three renowned scientists for the development of quantum dots -- nanoparticles so small that their properties are determined by quantum phenomena. Quantum dots are used to illuminate televisions and computer screens, LED lamps, and help guide surgeons in removal of tumor tissue.

Finding explanation for Milky Way's warp
The Milky Way is often depicted as a flat, spinning disk of dust, gas, and stars. But if you could zoom out and take an edge-on photo, it actually has a distinctive warp -- as if you tried to twist and bend a vinyl LP.
Tuning a Fundamental Material Property with an Electronic Coating
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.
Pingpong Balls Score Big as Sound Absorbers
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.
NASA's Webb Captures an Ethereal View of NGC 346
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.
