Scientists have come a step closer to understanding how collisionless shock waves—found throughout the universe—are able to accelerate particles to extreme speeds. Go to Source Since the invention of the laser in 1960, nonlinear optics has aimed to broaden light’s spectral range and create new frequency components. Among the various techniques, supercontinuum (SC) generation stands out for its ability to produce light across a wide portion of the visible and infrared spectrum. Go to Source Science is always looking for more computing power and more efficient tools capable of answering its questions. Quantum computers are the new frontier in data processing, as they use the quantum properties of matter, such as the superposition of states and entanglement, to perform very complex operations. Go to Source A team of physicists led by The City College of New York’s Lia Krusin-Elbaum has developed a novel technique that uses hydrogen cations (H+) to manipulate relativistic electronic bandstructures in a magnetic Weyl semimetal—a topological material where electrons mimic massless particles called Weyl fermions. These particles are distinguished by their chirality or “handedness” linked to […] Multiterminal Josephson junctions, nanoscale devices with unique electronic properties, comprise non-superconducting metallic material coupled to three or more superconducting leads. These devices have proved to be promising platforms for the exploration of topological phenomena in condensed matter physics. Go to Source Alexander Hartmann, a physicist at the University of Oldenburg, in Germany, has introduced a new model to explain a common word puzzle phenomenon. In his paper published in the journal Physical Review E, he suggests that instances where a puzzle solver experiences a sudden insight that allows them to begin finding solutions that seemed hidden […] Molecular crystals with conductivity and magnetism, due to their low impurity concentrations, provide valuable insights into valence electrons. They have helped link charge ordering to superconductivity and to explore quantum spin liquids, where electron spins remain disordered even at extremely low temperatures. Go to Source The development of sustainable energy sources that can satisfy the world energy demand is one of the most challenging scientific problems. Nuclear fusion, the energy source of stars, is a clean and virtually unlimited energy source that appears as a promising candidate. Go to Source Epithelial tissues are in constant interaction with their environment. Maintaining their functionality requires dynamic balance (homeostasis) and that their cell numbers are tightly regulated. This is achieved by cell extrusion programs, a checkpoint mechanism eliminating unwanted or harmful cells. Go to Source In a new study published in Nature, researchers at the Indian Institute of Science (IISc) and collaborators show that the efficacy of a commonly used piezoelectric ceramic material can be dramatically increased just by reducing its thickness and by preventing atomic defects inadvertently formed during manufacturing. Go to Source Researchers have developed a new method for quickly detecting and identifying very low concentrations of gases. The new approach, called coherently controlled quartz-enhanced photoacoustic spectroscopy, could form the basis for highly sensitive real-time sensors for applications such as environmental monitoring, breath analysis and chemical process control. Go to Source Quantum computers require extreme cooling to perform reliable calculations. One of the challenges preventing quantum computers from entering society is the difficulty of freezing the qubits to temperatures close to absolute zero. Go to Source From the early days of quantum mechanics, scientists have thought that all particles can be categorized into one of two groups—bosons or fermions—based on their behavior. Go to Source A research team led by The Hong Kong University of Science and Technology (HKUST) has achieved a groundbreaking quantum simulation of the non-Hermitian skin effect in two dimensions using ultracold fermions, marking a significant advance in quantum physics research. Go to Source Ferroelectrics are special materials with polarized positive and negative charges—like a magnet has north and south poles—that can be reversed when external electricity is applied. The materials will remain in these reversed states until more power is applied, making them useful for data storage and wireless communication applications. Go to Source |
