Dark matter has long been a perplexing enigma in the world of science. It constitutes approximately 80% of the matter in the universe, yet it remains invisible to the naked eye. Despite its unseen nature, the effects of dark matter’s gravity are evident in the movement of celestial bodies. Countless particles of dark matter are

Understanding how transport networks evolve and take shape is crucial for optimizing their stability and resilience. While tree-like structures are efficient for transport, networks with loops tend to be more damage-resistant. Researchers from the Faculty of Physics at the University of Warsaw and the University of Arkansas set out to explore the conditions that promote
The concept of using ultrafast electrons to emit light, known as synchrotron radiation, has long been utilized in storage rings for materials research. However, the light emitted in this process is longitudinally incoherent, limiting its potential applications. Monochromators can be used to select individual wavelengths, but at the cost of reducing radiant power significantly. This
Supersymmetry (SUSY) is a theoretical framework in particle physics that posits the existence of a “superpartner” for every known particle. This theory, if proven correct, could help answer some of the fundamental questions in the field. In 2021, the CMS collaboration at the Large Hadron Collider (LHC) analyzed data collected from 2016 to 2018 in
Titanium-sapphire (Ti:sapphire) lasers are widely recognized for their remarkable performance in various fields such as quantum optics, spectroscopy, and neuroscience. However, their bulky size, high cost, and energy requirements have limited their real-world adoption. That is until now. Researchers at Stanford University have made a groundbreaking advancement by developing a chip-scale Ti:sapphire laser that is
The study published in Nature Communications by Rice University’s Qimiao Si and his team highlights the exciting potential of flat electronic bands at the Fermi level in the realm of quantum materials and quantum computing. This groundbreaking discovery opens up new possibilities for the design of novel electronic devices and quantum phases. Understanding Quantum Materials
For the past seventy years, scientists have been studying the concept of “kugelblitze” – black holes formed by intense concentrations of light. This idea has been linked to various astronomical phenomena and even proposed as a potential power source for futuristic spacecraft engines. However, recent research by a team from the University of Waterloo and
The recent collaboration between Professor Szameit’s research group at the University of Rostock and researchers from the Albert-Ludwigs-Universität Freiburg has led to a significant breakthrough in stabilizing the interference of two photons in optical chips through the concept of topologically protected wave propagation. This innovative research, published in Science, highlights the synthesis of seemingly unrelated
Superconductivity is a fascinating phenomenon where certain materials exhibit resistance-free electrical conductance at low temperatures. A recent study published in Physical Review Letters (PRL) delves into the potential of quadratic electron-phonon coupling in enhancing superconductivity by forming quantum bipolarons. This study opens up new possibilities for achieving high-temperature superconductivity, challenging conventional mechanisms. Electron-phonon coupling refers
Photonic alloys, combining multiple photonic crystals, have shown promise in controlling electromagnetic wave propagation. However, a major issue with these materials is light backscattering, which hinders data and energy transmission, ultimately affecting their performance as waveguides. A New Approach Recently, researchers at Shanxi University and the Hong Kong University of Science and Technology developed a
