Surprising signals can arise from the coupling of light particles.

Researchers at Lawrence Livermore National Laboratory (LLNL) have optimized and 3D-printed helix structures as optical materials for Terahertz (THz) frequencies, a potential way to address a technology gap for next-generation telecommunications, non-destructive evaluation, chemical/biological sensing and more. The printed microscale helixes reliably create circularly polarized beams in the THz range and, when arranged in patterned arrays, can function as a new type of Quick R

Using proteins from a common tobacco plant virus, McGill chemistry researchers have developed a simple, eco-friendly way to arrange gold nanoparticles into ultrathin sheets, strengthening the particles’ optical properties. The result: cheaper, safer materials for solar panels, sensors and advanced optical devices. Gold nanoparticles are only effective in strengthening optical signals when the nanoparticles are arranged on a surface and spaced at exact distances. Until now, cr

A team from the Faculty of Physics and the Centre for Quantum Optical Technologies at the Centre of New Technologies, University of Warsaw has developed a new method for measuring elusive terahertz signals using a "quantum antenna." The authors of the work utilized a novel setup for radio wave detection with Rydberg atoms to not only detect but also precisely calibrate a so-called frequency comb in the terahertz band. This band was until recently a white spot in the electroma

One of the enigmas of life is emergence, when the whole becomes more than its parts. Flocks of birds can instantly change direction when a predator appears, guided not by a lead bird but by a collective intelligence that no single bird can possess on its own. Multitudes of molecules skitter chaotically in a cell, but certain ones find each other, interact, and give rise to sophisticated cellular structures and functions that could not have been predicted by studying the molec

For a long time, the two areas of strong-field physics and quantum optics were considered independent areas of physics research without any significant overlaps. Whilst strong-field physics focuses on the behavior of material, such as atomic gases, in intense light fields, quantum optics focuses on researching special quantum properties of light that cannot be described within the framework of classical physics. Strong-field physics requires intense laser rays, in other words
