Physicists uncover hidden order in the quantum world through deconfined quantum critical points

In the intricate world of quantum physics, where particles interact in ways that seem to defy the standard rules of space and time, lies a profound mystery that continues to captivate scientists: the nature of deconfined quantum critical points (DQCPs). These elusive critical phenomena break away from the conventional framework of physics, offering a fascinating […]

Search for sterile neutrinos continues at nuclear reactors

Neutrinos, elusive fundamental particles, can act as a window into the center of a nuclear reactor, the interior of the Earth, or some of the most dynamic objects in the universe. Their tendency to change “flavors” may provide clues into the prominence of matter over antimatter in the universe or explain the existence of dark […]

Secrets of superfluid: How dipolar interactions shape two-dimensional superfluid behavior

In a recent study, researchers made a significant observation of the Berezinskii-Kosterlitz-Thouless (BKT) phase transition in a 2D dipolar gas of ultracold atoms. This work marks a milestone in understanding how 2D superfluids behave with long-range and anisotropic dipolar interactions. The researchers are an international team of physicists, led by Prof. Jo Gyu-Boong from the […]

Rare one-dimensional quantum magnetism discovered in metallic Ti₄MnBi₂ compound

A study by researchers from the University of British Columbia’s Blusson Quantum Matter Institute (UBC Blusson QMI) has found a rare form of one-dimensional quantum magnetism in the metallic compound Ti4MnBi2, offering evidence into a phase space that has remained, until now, largely theoretical.

Tying light from lasers into stable ‘optical knots’

Knots are generally understood to form due to twists and turns of long, flexible materials that keep shoes on your feet or frustrate your attempts at hanging holiday decorations. A beam of light doesn’t sound like a material that can create a knot.

Chirality induces giant charge rectification in a superconductor

Recent studies have revealed that electrons passing through chiral molecules exhibit significant spin polarization—a phenomenon known as chirality-induced spin selectivity. This effect stems from a nontrivial coupling between electron motion and spin within chiral structures, yet quantifying it remains challenging.

Multivalley semiconductor enables optical switching in germanium for high-speed computing and communications

Opaque materials can transmit light when excited by a high-intensity laser beam. This process, known as optical bleaching, induces a nonlinear effect that temporarily alters the properties of a material. Remarkably, when the laser is switched on and off at ultrahigh speeds, the effect can be dynamically controlled, opening new possibilities for advanced optical technologies. […]

Magnetic force training helps AI take charge of material simulations

An international team of researchers has developed a new method for parameterizing machine-learning interatomic potentials (MLIP) to simulate magnetic materials, making the prediction of their properties much more reliable and accurate. A key feature of the new approach is that the models of interatomic interactions are trained on so-called “magnetic forces.”
