Researchers from Germany and the United States have discovered that terahertz (THz) light pulses can be used to stabilize ferromagnetism in a crystal at temperatures more than three times its usual transition temperature. This breakthrough could revolutionize processing speeds and efficiency. Details of the Study The team used pulses that were hundreds of femtoseconds long,

Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) have developed a new technique to measure the masses of key nuclei with high precision. Using this method, they have studied X-ray bursts on the surface of a neutron star, which has provided new insights into the properties of these
Los Alamos scientists have achieved light amplification using electrically driven devices based on solution-cast semiconductor nanocrystals. These tiny specs of semiconductor matter are made through chemical synthesis, also known as colloidal quantum dots. This breakthrough, reported in the journal Nature, opens the door to a completely new class of electrically pumped lasing devices. These laser
Researchers at the University of Connecticut have discovered a method for creating topological superconductors by manipulating quantum particles in thin layers of ordinary superconductors. Superconductors can conduct electric current without any resistance or energy loss, making them a potential game-changer in many fields, from energy transmission to quantum computing to MRI machines. However, creating superconductors
Researchers have developed a prototype lidar system using quantum detection technology to obtain 3D images while submerged underwater. The system has high sensitivity, which may allow it to capture detailed information even in low-light conditions found underwater. The technology could be useful for a range of applications, including inspecting underwater installations, monitoring or surveying submerged
Researchers at the University of Maryland (UMD) have come up with a new way of optical guiding using auxiliary ultrashort laser pulses to form a ring of high-intensity light structures called “filaments.” These filaments heat the air molecules to create an extended ring of low-density heated air that surrounds a central undisturbed region, which is
When light interacts with matter, it can produce unique quasi-particles known as polaritons. These particles are half light and half matter. Polaritons have been studied by physicists for a few decades now, with researchers exploring their potential for developing highly performing lasers or other technologies. Development of a High-Performing Device Researchers at the University of
Factorizing large numbers is a difficult task that requires a significant amount of computational effort. However, physicists at the University of Innsbruck, Austria, have created a new blueprint for a quantum computer that can solve the factorization problem. This is a significant development as factorization is a cornerstone of modern cryptography. Current Computing Methods Today’s
In the field of physics, it is common to encounter different scales that can be separately described. For instance, the movement of an elephant walking in a zoo does not affect the Earth’s orbit around the sun. Similarly, the behavior of particles in materials research can be described on different scales. However, finding out which
