A research team has taken a major step forward in the field of spintronics, a technology that uses not only the charge but also the spin of electrons to create faster, smarter, and more energy-efficient electronic devices. Their discovery could pave the way for the next generation of memory chips that combine high speed with […] The artificial intelligence (AI) boom has created unprecedented demand for data traffic. But the infrastructure needed to support it faces mounting challenges. AI data centers must deliver faster, more reliable communication than ever before, while also confronting their soaring electricity use and a looming quantum security threat, which could one day break today’s encryption methods. […] EPFL researchers have discovered that a droplet of liquid can bounce for several minutes—and perhaps indefinitely—over a vibrating solid surface. The seemingly simple observation has big implications for physics and chemistry. Go to Source Researchers at University of Tsukuba have successfully measured electric fields near the surfaces of two-dimensional layered materials with femtosecond temporal and nanometer spatial resolution. They employed a diamond containing a nitrogen-vacancy center—a lattice defect—as a probe within an atomic force microscope, enabling atomic-scale spatial precision. Go to Source Researchers at Umeå University and the Swedish Defense Research Agency, FOI, have developed new laser methods that can quickly detect chemical weapons and harmful bacteria directly on site—without the need to send samples to a laboratory. Go to Source What happens when electrons leave a solid material? This seemingly simple phenomenon has, until now, eluded accurate theoretical description. In a new study, researchers have found the missing piece of the puzzle. Go to Source Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to develop a wide range of advanced technologies, including optical photonic, sensing and communication systems. Go to Source In the right combinations and conditions, two-dimensional materials can host intriguing and potentially valuable quantum phases, like superconductivity and unique forms of magnetism. Why they occur, and how they can be controlled, is of considerable interest among physicists and engineers. Research published in Nature Physics reveals a previously hidden feature that could explain how and […] New research shows that dark matter has a different distribution in our galaxy than previously thought, and that advances dark matter’s status as a potential source of the observed gamma ray excess in the Milky Way’s center. High-resolution simulations reveal that the dark matter distribution in the inner galaxy is not spherical, but flattened and […] The simulation of strongly interacting many-body systems is a key objective of quantum physics research, as it can help to test the predictions of physics theories and yield new valuable insight. Researchers at Quantinuum, a quantum computing company, recently simulated a simplified version of a well-known theoretical model, the so-called Sachdev-Ye-Kitaev (SYK) model, using a […] The nature of dark matter remains one of the greatest mysteries in cosmology. Within the standard framework of non-collisional cold dark matter (CDM), various models are considered: WIMPs (Weakly Interacting Massive Particles, with masses of around 100 GeV/c2), primordial black holes, and ultralight axion-like particles (mass of 10-22 to 1 eV/c2). In the latter case, […] Shock waves should not be shocking—engineers across scientific fields need to be able to precisely predict how the instant and strong pressure changes initiate and dissipate to prevent damage. Now, thanks to a team from Yokohama National University, those predictions are even better understood. Go to Source Networks are systems comprised of two or more connected devices, biological organisms or other components, which typically share information with each other. Understanding how information moves between these connected components, also known as nodes, could help to advance research focusing on numerous topics, ranging from artificial intelligence (AI) to neuroscience. Go to Source […] Detecting dark matter—the mysterious substance that holds galaxies together—is one of the greatest unsolved problems in physics. Although it cannot be seen or touched directly, scientists believe dark matter leaves weak signals that could be captured by highly sensitive quantum devices. Go to Source A new twist on a classic material could advance quantum computing and make modern data centers more energy efficient, according to a team led by researchers at Penn State. Go to Source |
