From fundamental physics of light-matter interaction to fabrication of targeted optical properties in highly complex optical engineering, the femtosecond (fs) laser plays a crucial role in laser manufacturing. Ultrashort ...
When optical beams, consisting of photons, travel through fibers, they cause vibrations that generate acoustic waves, consisting of phonons. The phenomenon, called Brillouin scattering, has been harnessed by researchers to ...
Researchers from North Carolina State University and the University of North Carolina at Chapel Hill used chiral phonons to convert wasted heat into spin information—without needing magnetic materials. The finding could lead ...
Exceptional points are a distinct type of spectral singularity in non-Hermitian systems and their intriguing physics are in study with optical exceptional points. Exceptional points are singularities in the energy functions ...
The advent of intense ultrashort coherent light pulses has revolutionized the spectroscopy field. They allow easy observation of various nonlinear optical effects and facilitate the characterization of materials with nonlinear ...
Scientists have found the secret behind a property of solid materials known as ferroelectrics, showing that quasiparticles moving in wave-like patterns among vibrating atoms carry enough heat to turn the material into a thermal ...
Starting with the emergence of quantum mechanics, the world of physics has been divided between classical and quantum physics. Classical physics deals with the motions of objects we typically see every day in the macroscopic ...
Scientists working on laser application at the RIKEN Center for Advanced Photonics (RAP) have demonstrated that GHz burst mode femtosecond laser pulses can create unique two-dimensional (2D) laser-induced periodic surface ...
Using a quantum simulator, researchers at the Max Planck Institute of Quantum Optics (MPQ) have observed pairs of charge carriers that may be responsible for the resistance-free transport of electric current in high-temperature ...
Topological phases are not restricted to electronic systems. They can also occur in magnetic materials whose properties are described in terms of magnetic waves—or so-called magnons. However, even though scientists have established ...
