Opaque materials can transmit light when excited by a high-intensity laser beam. This process, known as optical bleaching, induces a nonlinear effect that temporarily alters the properties of a material. Remarkably, when the laser is switched on and off at ultrahigh speeds, the effect can be dynamically controlled, opening new possibilities for advanced optical technologies. […] An international team of researchers has developed a new method for parameterizing machine-learning interatomic potentials (MLIP) to simulate magnetic materials, making the prediction of their properties much more reliable and accurate. A key feature of the new approach is that the models of interatomic interactions are trained on so-called “magnetic forces.” Go to Source […] In a major step forward for radiation detection technology, a research team led by Prof. Meng Gang from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has significantly enhanced the performance of CsPbBr3-based X-ray detectors by dramatically lowering their detection limit and suppressing noise and ion migration through innovative cooling and […] With millions of dollars at stake across tournaments and more than 45 million regular annual participants, bowling continues to reign as a top sport in the U.S. A unified model that predicts how a bowling ball behaves down the lane, however, remains elusive. Go to Source Diamonds with certain optically active defects can be used as highly sensitive sensors or qubits for quantum computers, where the quantum information is stored in the electron spin state of these color centers. However, the spin states have to be read out optically, which is often experimentally complex. Now, a team at HZB has developed […] In the realm of general relativity, black holes are well-known for their ability to trap light and matter by bending spacetime, creating a point of no return. While black holes have fascinated scientists and the public alike, another concept, the white hole, has remained more theoretical. A white hole is thought to be the reverse […] The University of Jyväskylä (Finland), in collaboration with the Finnish Radiation and Nuclear Safety Authority (STUK), has developed a new type of handheld multi-purpose radiation detector that comprehensively detects all types of ionizing radiation. The device can be used by industrial and medical radiation users, regulatory authorities, the nuclear energy industry, first responders and military […] A new study published in Nature Communications April 7 could reshape the future of magnetic and electronic technology. Scientists at Rice University have discovered how a disappearing electronic pattern in a quantum material can be revived under specific thermal conditions. The finding opens new doors for customizable quantum materials and in-situ engineering, where devices are […] A research team has successfully fine-tuned the Rabi oscillation of polaritons, quantum composite particles, by leveraging changes in electrical properties induced by crystal structure transformation. Published in Advanced Science, this study demonstrates that the properties of quantum particles can be controlled without the need for complex external devices, which is expected to greatly enhance the […] Superconductivity—the ability of some materials to conduct electricity with no energy loss—holds immense promise for new technologies from lossless power grids to advanced quantum devices. Go to Source Rapidly increasing data traffic is placing ever greater demands on the capacity of communication systems. In an article titled “Ultra-broadband optical amplification using nonlinear integrated waveguides” published in Nature, a research team from Chalmers University of Technology, in Sweden, introduce a new amplifier that enables the transmission of 10 times more data per second than […] Superconductivity is a quantum property of materials entailing an electrical resistance of zero at very low temperatures. In some materials, multiple electronic bands are known to contribute to the emergence of superconductivity, leading to multiple superconducting energy gaps. This phenomenon is referred to as multiband superconductivity. Go to Source Anyone who’s ever tried tiling a floor, a backsplash or even an arts-and-crafts project probably knows the emotional frustration of working with pieces whose shapes don’t perfectly complement each other. It turns out, though, that some creatures may actually rely on similar mismatches to create geometric frustrations that result in complex natural structures with remarkable […] Researchers have successfully demonstrated the UK’s first long-distance ultra-secure transfer of data over a quantum communications network, including the UK’s first long-distance quantum-secured video call. Go to Source Quantum systems are known to be prone to dissipation, a process that entails the irreversible loss of energy and that is typically linked to decoherence. Decoherence, or the loss of coherence, occurs when interactions between a quantum system and its environment cause a loss of coherence, which is ultimately what allows quantum systems to exist […] |
