Quantum Hall effect gains a new twist in graphene moiré systems

Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an electric voltage appears perpendicular to a current flowing through a material. Unlike its classical counterpart, the nonlinear version can arise even without breaking time-reversal symmetry, and its magnitude is tied to deep geometric properties […]

Random deformation lets glassy materials store precise mechanical memories, simulations reveal

Amorphous materials such as glass are solids whose internal structure lacks a repeating pattern. Their molecules are arranged in a random and irregular way. Surprisingly, these disordered materials can “remember” past mechanical experiences; that is, the way they respond to a force can depend on how they have responded to external forces before.

Quantum hyperdimensional computing can work 500 times faster than other methods

Cleveland Clinic researchers are unlocking quantum computing’s full potential through the creation of a new computing paradigm inspired by the human brain. Fabio Cumbo, Ph.D., research associate in the lab of Daniel Blankenberg, Ph.D., associate staff, Computational Life Sciences, is developing the model, called quantum hyperdimensional computing (QHDC).

Intermolecular collisions may explain why organic radical fluids become unusually magnetic

Certain substances can become magnetic when exposed to an external magnetic field. Magnetic susceptibility measures how easily a material can be magnetized. Materials known as organic radicals have been noted to possess anomalously large magnetic susceptibility. However, researchers have been unable to explain this phenomenon using conventional theories.

High degree of quantum entanglement detected for first time in centimeter-sized crystal of strange metal

Many quantum effects can be observed only when a small number of particles is studied—individual atoms, molecules or photons, for example, carefully shielded from the rest of the world. But what about macroscopic objects, consisting of an unimaginably large number of particles? Can they, too, display effects that provide a direct glimpse into the quantum […]

Rare B meson decays tighten search for hidden particles and dark matter links

A University of Melbourne researcher has placed the strongest constraints yet on certain rare decays of subatomic particles, narrowing the window for where new “hidden” particles could be lurking.

Abstract algebra unlocks distinguishable states for quantum systems

Researchers around the world are racing to develop new quantum-based systems for sensing, communication, computing and control that have the promise of outperforming traditional systems. Creating stable, measurable, distinguishable quantum states—which would be the heart of any such system—is a daunting task.

Ultrafast laser pulses reveal a material’s hidden state of matter

What would it take to instantly transform a material from an electrical insulator into a conductive state without ever touching it? Using ultrafast laser pulses and powerful X-rays, scientists at the National Synchrotron Light Source II (NSLS-II)—a U.S. Department of Energy (DOE) Office of Science user facility at DOE’s Brookhaven National Laboratory—developed a methodology to […]

Most precise measurement of the force that binds nuclear matter achieved

Trinity’s Prof. Stefan Sint, along with collaborators from Germany, Spain and Italy, has published the most precise determination to date of the strong coupling constant. This parameter governs the interactions between quarks and gluons, the fundamental components of nuclear matter. The new result halves the error of all previous experimental measurements combined, setting a new […]

Passive quantum error correction doubles qubit lifetime, reaching break-even point

A team of U.S. researchers has designed a passive quantum error correction technique that enables qubits to correct their own errors. Demonstrated by Shruti Shirol and colleagues at the University of Massachusetts Amherst, the protocol transforms the inevitable dissipation of energy in qubit systems from a hindrance into an advantage, offering a promising route toward […]

Quasi-1D material unlocks electric control of charge waves beyond standard limits

The ability to control the movement of negatively charged particles (i.e., electrons) is central to the functioning of all modern electronic devices. This control is typically attained using a gate, an electrode via which an applied electric field alters a material’s electrical properties.

Light-programmed system projects 28-layer 3D images in single shot

Researchers at the UCLA Samueli School of Engineering and CNSI (California NanoSystems Institute), led by Professor Aydogan Ozcan, introduced a snapshot 3D image projection system that integrates a digital encoder with a passive diffractive optical decoder, jointly optimized end-to-end through deep learning. The hybrid architecture projects multiple distinct images onto closely spaced axial planes in […]

Unique chromium beam experiment unlocks cosmic ray origins and galactic chemistry

When a star dies, it generates an explosion of elemental nuclei and hurls them into space. Those elements, called cosmic rays, travel at nearly the speed of light, and eventually some of them encounter manmade detectors. Recording how many of each of these elements show up helps scientists better understand cosmic processes—but despite incredible research […]
