Over the past few years, some researchers have been working on alternative energy storage systems that leverage the principles of quantum mechanics. These systems, known as quantum batteries, could be more efficient and compact than conventional battery technologies, while also achieving faster charging times. Go to Source Time is vital to the functioning of our everyday lives: from the watches on our wrists to the GPS systems in our phones. Communication systems, power grids, and financial transactions all rely on precision timing. Seconds are the vital units of measurement in timekeeping. Go to Source Perovskites, materials with a crystal structure that mirrors that of the mineral calcium titanate CaTiO₃, exhibit properties that are advantageous for developing various technologies. For instance, they have proved promising for designing photovoltaic (PV) systems and electronic devices. Go to Source Theoretical physicists have established a close connection between the two rapidly developing fields in theoretical physics, quantum information theory and non-invertible symmetries in particle and condensed matter theories, after proving that any non-invertible symmetry operation in theoretical physics is a quantum operation. The study was published in Physical Review Letters as an Editors’ Suggestion on […] In a study at the University of Twente, researchers discovered a way to scatter light in a special, symmetrical way using nanotechnology. This shows potential for future technologies such as anti-counterfeiting. Go to Source Since it was first demonstrated in the 1960s, spontaneous parametric down-conversion (SPDC) has been at the center of many quantum optics experiments that test the fundamental laws of physics in quantum mechanics, and in applications like quantum simulation, quantum cryptography, and quantum metrology. Go to Source Higher-density storage technique could allow diamond disk to store equivalent of 2,000 Blu-ray discsA team of engineers at the University of Science and Technology of China has developed a new way to code data onto a diamond with higher density than prior methods. In their paper published in the journal Nature Photonics, the group notes that such optical discs could hold data safely at room temperature for millions […] Physicists from the University of the Witwatersrand (Wits) have developed an innovative computing system using laser beams and everyday display technology, marking a significant leap forward in the quest for more powerful quantum computing solutions. Go to Source A research team, led by Professor Jung-Woo Yoo from the Department of Materials Science and Engineering at UNIST has unveiled a new type of magnetic memory device, designed to reduce power consumption and heat generation in MRAM semiconductors. The work was published in Nature Communications on October 10, 2024. Go to Source […] A team of physics educators from Italy, Hungary, Slovenia and Germany is focusing on a new approach to teaching quantum physics in schools. Traditional classroom teaching has tended to focus on presenting the history of the origins of quantum physics, which often poses problems for learners. Go to Source Improved spin and density correlation simulations give researchers clearer insights on neutron starsWhen a star dies in a supernova, one possible outcome is for the remains to become a neutron star. Inside a neutron star, the protons and electrons combine into uncharged neutrons. This substance is called neutron matter. Go to Source A team led by Francesca Ferlaino has set a new milestone in atomic physics by trapping individual erbium atoms in optical tweezers for the first time. Taking advantage of erbium’s complex electronic structure, which opens up new degrees of freedom and possibilities, this advancement opens the door to a range of innovative experiments in quantum […] Whether it’s our phones, cars, televisions, medical devices or even washing machines, we now have computers everywhere. Go to Source It’s a paper that’s been more than four decades in the making. Published in Physical Review Accelerators and Beams, a study has re-benchmarked the main particle accelerator at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility. It has captured the accelerator’s original and upgraded operating parameters and describes in detail its main systems […] Thermoelectric materials, which convert heat into electricity, are valuable tools for capturing waste heat and turning it into usable electricity. These materials are especially useful in industries and vehicles where engines produce a lot of waste heat, improving energy efficiency by converting it into additional power. They also exhibit potential for portable power generation, in […] |
