Researchers have announced results from a new search at the European X-ray Free Electron Laser (European XFEL) Facility at Hamburg for a hypothetical particle that may make up the dark matter of the universe.
The article from MSN discusses a groundbreaking X-ray experiment aimed at resolving significant puzzles in physics, particularly those related to the behavior of matter under extreme conditions. Scientists at the European XFEL, a high-energy X-ray laser facility in Germany, have developed a new technique to study the electronic structure of materials at unprecedented time scales. This experiment utilizes the facility's ability to produce X-ray pulses at a rate of 27,000 times per second, allowing researchers to observe dynamic processes in materials like high-temperature superconductors and quantum materials. By capturing these fleeting states, the experiment seeks to provide insights into phenomena such as high-temperature superconductivity, which could lead to advancements in technology and our understanding of fundamental physics. The technique involves using X-ray photon correlation spectroscopy (XPCS) to measure how X-rays scatter off materials, revealing information about atomic and electronic movements. This could potentially answer long-standing questions about the nature of quantum entanglement, phase transitions, and the behavior of matter at the quantum level.
