Mechanical Engineering Professor Alan McGaughey of Carnegie Mellon University recently coordinated the Phonon Olympics, bringing together developers and expert users to benchmark three leading open-source thermal conductivity calculation packages. Go to Source Researchers from the Department of Molecular Physics at the Fritz Haber Institute have demonstrated the first magneto-optical trap of a stable “closed-shell” molecule: aluminum monofluoride (AlF). They were able to cool AlF with lasers and selectively trap it in three different rotational quantum levels—breaking new ground in ultracold physics. Go to Source […] The new big thing in magnetics is altermagnetism, a form of magnetism that promises to power the next generation of electronics. Unlike ferromagnets, like a fridge magnet, where all internal atomic spins align to create a strong magnetic field, altermagnets have no net magnetic pull (strongly magnetic on the inside, but appears non-magnetic on the […] Researchers from Stockholm University and the Indian Institute of Science Education and Research (IISER) Mohali have reported a practical way to spot one of physics’ strangest predictions: the Unruh effect, which says that an object speeding up (accelerating) would perceive empty space as faintly warm. But, trying to heat something up by accelerating it unimaginably […] The geometry of space, where physical laws unfold, may also hold answers to some of the deepest questions in fundamental physics. The very structure of spacetime might underlie every interaction in nature. Go to Source A new method for measuring three different properties of light, at the same time, has been developed using an interferometry-based quantum sensing scheme capable of simultaneously estimating multiple parameters of an optical network. Go to Source In a new study published in Nature Physics, researchers achieved the first experimental observation of a time rondeau crystal—a novel phase of matter where long-range temporal order coexists with short-time disorder. Go to Source Artificial intelligence (AI) systems, particularly artificial neural networks, have proved to be highly promising tools for uncovering patterns in large amounts of data that would otherwise be difficult to detect. Over the past decade, AI tools have been applied in a wide range of settings and fields. Go to Source Placing materials under extremely strong magnetic fields can give rise to unusual and fascinating physical phenomena or behavior. Specifically, studies show that under magnetic fields above 100 tesla (T), spins (i.e., intrinsic magnetic orientations of electrons) and atoms start forming new arrangements, promoting new phases of matter or stretching a crystal lattice. Go to Source […] High-temperature superconductivity is still not fully understood. Now, an international research team at BESSY II has measured the energy of charge carrier pairs in undoped La₂CuO₄. Their findings revealed that the interaction energies within the potentially superconducting copper oxide layers are significantly lower than those in the insulating lanthanum oxide layers. These results contribute to […] A team of researchers at the Max Born Institute have managed to fully characterize few-femtosecond-long light pulses tunable in the vacuum ultraviolet. These results unlock the possibility for studying valence electron dynamics of many materials in the VUV. The research is published in the journal Nature Photonics. Go to Source A team of European researchers has developed a versatile, open-source luminescence imaging instrument designed to democratize access to advanced fluorescence and electroluminescence techniques across disciplines ranging from plant science to materials research. Go to Source A research group led by Prof. Li Xiangyang from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has made a new discovery: a single organic molecule can induce the Kondo effect in a magnetic atom, challenging the long-standing belief that this quantum phenomenon requires a vast sea of metallic electrons. Go […] In the world of optics, tiny structures called microcavities—often no wider than a human hair—play a crucial role in technologies ranging from lasers to sensors. Go to Source Researchers have been developing computers that deploy light (photons) rather than electricity to power storage and calculations. These light-based computers have the potential to be more energy efficient than traditional computers while also running calculations at greater speeds. Go to Source |
