For countless millions across the globe, commuting to work or school is an everyday routine. But during a pandemic, the practice can contribute enormously to the spread of infectious disease, a fact that many traditional metapopulation models often overlook because they are designed primarily for migration and treat people as if they rarely move locally. […] Electrons in two-dimensional (2D) systems placed under strong magnetic fields often behave in unique ways, prompting the emergence of so-called fractional quantum Hall liquids. These are exotic states of matter in which electrons behave collectively and form new quasiparticles carrying only a fraction of an electron’s charge and obeying unusual quantum statistics. Go to Source […] Scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have discovered a way to control sound and vibrations using a concept inspired by “twistronics,” a phenomenon originally developed for electronics. Go to Source Professor Edmund Lam, Dr. Ni Chen and their research team from the Department of Electrical and Electronic Engineering under the Faculty of Engineering at the University of Hong Kong (HKU) have developed a novel uncertainty-aware Fourier ptychography (UA-FP) technology that significantly enhances imaging system stability in complex real-world environments. The research has been published in […] The world’s most sensitive table-top interferometric system—a miniature version of miles-long gravitational-wave detectors like LIGO—has completed its first science run. Go to Source Nobel Prize in physics awarded for ultracold electronics research that launched a quantum technologyQuantum mechanics describes the weird behavior of microscopic particles. Using quantum systems to perform computation promises to allow researchers to solve problems in areas from chemistry to cryptography that have so many possible solutions that they are beyond the capabilities of even the most powerful nonquantum computers possible. Go to Source Scientists have created the world’s hottest engine running at temperatures hotter than those reached in the sun’s core. The team from King’s College London and collaborators believe their platform could provide an unparalleled understanding of the laws of thermodynamics on a small scale, and provide the foundation for a new, efficient way to compute how […] Magnetic materials have been known since ancient times and play an important role in modern society, where the net magnetic order offers routes to energy harvesting and data processing. It is the net magnetic moment of ferromagnets that has so far been key to their applications, with an alternative type of magnetic material, the antiferromagnet, […] Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the precision of atomic clocks. Go to Source Imagine zooming into matter at the quantum scale, where tiny particles can interact in more than a trillion configurations at once. Go to Source Cornell researchers have built a programmable optical chip that can change the color of light by merging photons, without requiring a new chip for new colors. Go to Source For decades, scientists have observed, but been unable to explain, a phenomenon seen in some soft materials: When force is applied, these materials exhibit not one, but two spikes in energy dissipation, known as overshoots. Because overshoots are generally thought to indicate the point at which a material yields, or transitions from solid-like to fluid-like […] For decades, it’s been known that subtle chemical patterns exist in metal alloys, but researchers thought they were too minor to matter—or that they got erased during manufacturing. However, recent studies have shown that in laboratory settings, these patterns can change a metal’s properties, including its mechanical strength, durability, heat capacity, radiation tolerance, and more. […] A team of researchers at the Ming Hsieh Department of Electrical and Computer Engineering has created a new breakthrough in photonics: the design of the first optical device that follows the emerging framework of optical thermodynamics. Go to Source From computer chips to quantum dots—technological platforms were only made possible thanks to a detailed understanding of the used solid-state materials, such as silicon or more complex semiconductor materials. This understanding also includes being able to identify and control irregularities in the crystal lattice of such materials. Go to Source |
