Reliably verifying the location of a device connected to the internet or other networks is important for various real-world applications. For instance, it could be valuable for authorizing financial transactions, securing ...
Understanding the origin, acceleration and propagation of high-energy cosmic rays has been a century-old mystery in astrophysics. Recently, joint observations from China's Einstein Probe (EP) satellite and the Large High ...
Students in Cornell's Space Systems Design Studio (SSDS) have released mission results for two unique light-sail experiments. These sails are slightly larger than a pizza box and harness momentum from photons to accelerate ...
Quantum key distribution allows two users to establish secret keys whose security is grounded in the laws of quantum mechanics. Extending this capability to multiple users is an essential step toward quantum networks that ...
Ultrashort laser pulses can be used to generate X-rays. Normally, however, only certain specific frequencies are produced. A team from TU Wien and the University of California San Diego has developed a method that makes it ...
Photonic integrated circuits route information with optical signals instead of relying only on electrical currents. Silicon (Si) and silicon nitride (SiNx) are excellent photonic platforms for waveguides, but they cannot ...
The electronic properties of materials are typically determined by their structure under normal, undisturbed conditions, when they are in a state known as equilibrium. Intense light beams, however, can temporarily reshape ...
Multiferroics are materials that simultaneously exhibit two or more ferroic orders—stable arrangements of physical properties that can be switched using an external stimulus. These materials could be highly advantageous for ...
Beauty and mystery—it is hard to imagine a more alluring combination, and this is precisely what we encounter when we observe phenomena in the nanoworld. But are we really sure that observations made using modern microscopic ...
Physicists at The City College of New York have demonstrated a new way to transfer microwave signals onto light using magnetic waves inside a layered semiconductor. The work establishes a materials platform for building interfaces ...
