Spectroscopy is an essential field in both chemistry and astrophysics that focuses on analyzing the interaction between matter and electromagnetic radiation. By examining the unique spectral fingerprints emitted or absorbed by substances, researchers can identify chemical compounds, understand elemental compositions, and derive the physical properties of distant celestial bodies. Each substance and celestial body has

Recent advancements in material science have opened exciting avenues for the exploration of nonlinear optical effects, particularly in two-dimensional (2D) magnetic materials. Spearheaded by Professor Sheng Zhigao of the Hefei Institutes of Physical Science, a research team has made a groundbreaking discovery in the realm of nonlinear magnetic second harmonic generation (MSHG). The findings, published
The unfolding world of quantum dynamics has recently witnessed a significant breakthrough, as highlighted by a new study published in Physical Review Letters. Researchers have made the groundbreaking experimental observation of non-Hermitian edge bursts, which could reshape our understanding of quantum systems. Non-Hermitian physics stands apart from traditional Hermitian frameworks, primarily due to the complex
Rohit Velankar, a senior at Fox Chapel Area High School, stumbled upon a thought-provoking question while engaging in a simple, everyday act: pouring juice. The rhythmic “glug, glug, glug” sound that emerged as juice flowed from the carton led him to ponder the physics behind it. Specifically, he wondered whether the material elasticity of the
Neutrinos, elusive particles that abound in the universe, are at the heart of a significant breakthrough in particle physics, with researchers at the Short-Baseline Near Detector (SBND) at Fermilab making headlines by identifying their first interactions. This achievement is more than just a technical milestone; it lays the groundwork for a deeper understanding of the
