Physicists realize fractionalization without a magnetic field
Wannier states and schematic phase diagram. (a) Wannier states and a typical moiré pattern. The yellow and green blobs schematically represent the shape of Wannier orbitals on the BA and AB sublattices, respectively. (b) Schematic representation of the six-phase registry of AB-BA sites. The vertices of the triangle correspond to the three charge lobes. (c) Proposed phase diagram…

Using air to deflect lasers
Credit: Science Communication Lab for DESY Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original quality of the beam, reports an interdisciplinary research team in the journal…

Optimizing continuous-variable functions with quantum annealing
Credit: Tokyo Tech Quantum annealing (QA) is a cutting-edge algorithm that leverages the unique properties of quantum computing to tackle complex combinatorial optimization problems (a class of mathematical problems dealing with discrete-variable functions). Quantum computers use the rules of quantum physics to solve such problems potentially faster than classical computers. In essence, they can… Continue…

Perfect Cones Are as Weak as They Seem
October 3, 2023• Physics 16, s137 The early failure of thin-walled cones under compression was thought to arise mainly from the presence of imperfections. A new model suggests otherwise. Physicists simplify problems to make calculations easier, but doing so risks neglecting important physical properties, as illustrated by the fabled spherical cow in a vacuum,…

Unexpected Noise in Next-Generation Mirror Material
October 3, 2023• Physics 16, 170 A crystalline reflective coating being considered for future gravitational-wave detectors exhibits peculiar noise features at cryogenic temperatures. M. Heintze/Caltech/MIT/LIGO Lab Gravitational-wave detectors rely on mirrors that reflect without introducing too much noise into the light. M.
