by Research Laboratory of Electronics, MIT News Imagine how a phone call works: Your voice is converted into electronic signals, shifted up to higher frequencies, transmitted over long distances, and then shifted back down so it can be…

Researchers at Rensselaer Polytechnic Institute have fabricated a device no wider than a human hair that will help physicists investigate the fundamental nature of matter and light. Their findings, published in the journal Nature…

There are challenges in physics. For example, when light interacts with matter, light seems to slow down. When incident light (light that falls on a subject) is on an interface, the standard wave equation is satisfied on both sides. Solving…

According to fundamental physics, the properties of mass—weight, inertia, and gravitation—always remain the same relative to each other. If this is not true, Einstein's theory of relativity would be debunked. Now, however, quantum theory…

Optical manipulation of material properties could bring about new functions. For example, exciting electrons with strong light can lead to exotic quantum effects. The periodic perturbations from the strong light field cause electrons to…

In a study published in Nature Physics, Rice University physicists and collaborators presented an array of experimental evidence showing their charge density wave discovery was rarer than first thought--a case where the magnetic and…

Every light wave is characterized by its frequency and the human eye can detect frequencies between 400 and 750 trillion Hz (or terahertz, THz), which define the visible spectrum. Cell phone camera light sensors detect frequencies down to…

Physicists created a new ultra-thin two-layer material with quantum properties that normally require rare earth compounds. This material is easy to make and does not contain rare earth metals, and it may provide a new platform for quantum…

Physicists at the Universities of Bristol, Vienna, the Balearic Islands and the Institute for Quantum Optics and Quantum Information (IQOQI-Vienna) have demonstrated how quantum systems simultaneously evolve along two opposite time arrows,…

While we know that with superconductivity, electrons form pairs. Can they also condense into foursomes? According to a paper in Nature Physics, Professor Egor Babaev and collaborators at KTH Royal Institute of Technology presented evidence…
