Bloch oscillations are periodic oscillations of quantum particles in a repeating energy "landscape" (e.g., a crystal lattice) that are subjected to a constant force. These particle motions have been the focus of numerous ...
Imagine a clock that doesn't have electricity, but its hands and gears spin on their own for all eternity. In a new study, physicists at the University of Colorado Boulder have used liquid crystals, the same materials that ...
From precision machining to advanced microscopy, the demand for higher-power, ultrafast lasers continues to grow. Traditionally, researchers have relied on single-mode fibers to build these lasers, but they face a fundamental ...
Optical frequency combs, as a time and frequency "ruler," have important applications in precision ranging. Conventional dual-comb ranging schemes utilize the optical Vernier effect to achieve long-distance measurements, ...
Solitonic waves—waves that keep their shape and direction of motion for a long time—have intrigued physicists for almost two centuries. In real-world circumstances, these waves eventually die out due to energy loss. A ...
Cornell researchers have developed a two-phase liquid crystal system that can rapidly change—and hold—its shape, transforming from a transparent thin liquid film to an opaque emulsion, and then back again, all with a ...
Do you think you know which species are most vulnerable in an ecosystem? A novel analytical method developed by Italian physicists at the Complexity Science Hub (CSH) suggests there's more to discover. In their recent study, ...
A study in Nature describes both the mechanism and the material conditions necessary for superfluorescence at room temperature. The work could serve as a blueprint for designing materials that allow exotic quantum states—such ...
What if the magnon Hall effect, which processes information using magnons (spin waves) capable of current-free information transfer with magnets, could overcome its current limitation of being possible only on a 2D plane? ...
Laser frequency combs are light sources that produce evenly spaced, sharp lines across the spectrum, resembling the teeth of a comb. They serve as precise rulers for measuring time and frequency, and have become essential ...
