Researchers have for the first time observed a time crystal on a microscale semiconductor chip oscillating at a rate of several billion times per second, unveiling exceptionally high non-linear dynamics in the GHz range.
Materials scientists and engineers would like to know precisely how electrons interact and move in new materials and how the devices made with them will behave. Will the electrical current flow easily within the material? ...
Terahertz waves, known as non-ionizing radiation, can turn into ionization radiation when sufficiently many terahertz photons are focused in space and time. A team led by scientists in Korea and the U.S. has created the world's ...
Transistors are the basis for microchips and the whole electronic industry. The invention of transistors, by Bardeen and Brattain in 1947, awarded with a Nobel prize, is regarded as one of the most important discoveries of ...
Many of today's quantum devices rely on collections of qubits, also called spins. These quantum bits have only two energy levels, the "0" and the "1." However, spins in real devices also interact with light and vibrations ...
Quantum information science is truly fascinating—pairs of tiny particles can be entangled such that an operation on either one will affect them both even if they are physically separated. A seemingly magical process called ...
Superconductors are materials that can conduct electricity with zero resistance when they are cooled below a certain critical temperature. They have applications in several fields, including magnetic resonance imaging, particle ...
Diamond is the hardest material found in nature—diamond also has the highest thermal conductivity, allowing the most heat to flow through it rapidly.
Researchers at the University of Rochester have used surface acoustic waves to overcome a significant obstacle in the quest to realize a quantum internet.
The nuclear reactions that power the stars and forge the elements emerge from the interactions of the quantum mechanical particles, protons and neutrons. Explaining these processes is one of the most challenging unsolved ...
