Researchers at the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, together with international collaborators, have developed two complementary methods that could make quantum communication via fiber ...
Randomness is incredibly useful. People often draw straws, throw dice or flip coins to make fair choices. Random numbers can enable auditors to make completely unbiased selections. Randomness is also key in security; if a ...
Kerr microcombs are sets of equidistant spectral lines generated by pumping a high-Q microresonator with a resonant continuous-wave single-mode laser. They have arguably created a new field in cavity nonlinear photonics, ...
Sunlight sparkling on water evokes the rich phenomena of liquid-light interaction, spanning spatial and temporal scales. While the dynamics of liquids have fascinated researchers for decades, the rise of neuromorphic computing ...
Intense mid-infrared excitation has been demonstrated as a powerful tool for controlling the magnetic, ferroelectric and superconducting properties of complex materials. Nonlinear phononics is key to this end, as it displaces ...
The 3D Dirac and Weyl semimetals can be characterized by a charge chirality with the parallel or antiparallel locking of electron spin in its momentum. Such materials can exhibit a chiral magnetic effect associated with the ...
The traditional mathematical model of predator-prey relations in the wild does not take into account indirect nonlocal interactions. However, according to a mathematician from RUDN University, they affect the dynamics of ...
Sometimes in shallow water, a type of wave can form that is much more stable than ordinary waves. Called solitons, these phenomena emerge as solitary waves and can travel long distances while maintaining their shape and speed, ...
In quantum electrodynamics, the choice of gauge (i.e. specific mathematical formalism used to regulate degrees of freedom) can greatly influence the form of light-matter interactions. Interestingly, however, the "gauge invariance" ...
New photonic tools for medical imaging can be used to understand the nonlinear behavior of laser light in human blood for theranostic applications. When light enters biological fluids it is quickly scattered, however, some ...
