In the everyday world, governed by classical physics, the concept of equilibrium reigns. If you put a drop of ink into water, it will eventually evenly mix. If you put a glass of ice water on the kitchen table, it will eventually ...
Scientists are proposing to build a laser in a crater on the moon to help future lunar missions land safely in the dark and find their way around. This ultra-stable light source could also help us keep time more accurately, ...
Researchers in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Faculty of Arts and Sciences have devised a new way to make some of the smallest, smoothest mirrors ever created for controlling ...
Lasers, devices that emit intense beams of coherent light in specific directions, are widely used in research settings and are central components of various technologies, including optical clocks (i.e., systems that can keep ...
Forecasting earthquakes presents a serious challenge on land, but in the oceans that cover around 70% of Earth's surface it is all but impossible. However, the vast network of undersea cables that crisscross the world's seas ...
In a quiet laboratory, a team of atmospheric scientists and engineers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory recently gathered around a workstation to watch as little floating speckles, illuminated ...
A team of physicists from the University of Ottawa, led by Neda Boroumand, have developed a new theoretical model that shines new light on how scientists understand the way lasers interact with dense matter, such as solids ...
Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, including quantum key distribution (QKDs). However, conventional polarization-based entanglement states ...
When an electron travels through a polar crystalline solid, its negative charge attracts the positively charged atomic cores, causing the surrounding crystal lattice to deform. The electron and lattice distortion then move ...
Physicists in Germany have carried out the most accurate measurement to date of the width of the proton. By examining a previously unexplored energy-level transition in the hydrogen atom, Lothar Maisenbacher and colleagues ...
