Anything-goes 'anyons' may be at the root of surprising quantum experiments

In the past year, two separate experiments in two different materials captured the same confounding scenario: the coexistence of superconductivity and magnetism. Scientists had assumed that these two quantum states are mutually ...

A simple spin swap reveals exotic anyons

Researchers from the University of Innsbruck, the Collège de France, and the Université Libre de Bruxelles have developed a simple yet powerful method to reveal anyons—exotic quantum particles that are neither bosons nor ...

CERN's ATLAS detects evidence for decay of Higgs boson into muon–antimuon pair

Although its existence had been theorized for decades, the Higgs boson was finally observed to exist in 2012 at the Large Hadron Collider (LHC) at CERN. Since then, it has continued to be heavily studied at the LHC. Now, ...

Quantum nonlocality may be inherent in the very nature of identical particles

At its deepest physical foundations, the world appears to be nonlocal: particles separated in space behave not as independent quantum systems, but as parts of a single one. Polish physicists have now shown that such nonlocality—arising ...

Exploring how dark matter alters electron-capture supernovae and the birth of neutron stars

Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become unstable when electrons are ...

Simplified Sachdev-Ye-Kitaev model simulated on trapped-ion quantum computer

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, ...

Strontium optical lattice clock exhibits record-high coherence time

Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct quantum states at a particular ...

A new approach to magnify wave functions when imaging interacting ultracold atoms

The precise imaging of many-body systems, which are comprised of many interacting particles, can help to validate theoretical models and better understand how individual particles in these systems influence each other. Ultracold ...

New 3D topological phase of matter exhibits anomalous symmetry at non-zero temperatures

Some phases of matter cannot be described using the conventional framework of symmetry breaking and exhibit a so-called quantum order. One type of quantum order, known as topological order, is characterized by long-range ...

Neutrino masses are not likely to originate from interactions with dark matter, study finds

Neutrinos are fundamental particles characterized by no electric charge and very small masses, which are known to interact with other matter via the weak force or gravity. While these particles have been the focus of numerous ...
