Technology advance could enable space-based atomic clocks, improving communications and GPS navigation. Although quantum technology has proven valuable for highly precise timekeeping, making these technologies…
The study marks a major step toward creating a system for studying quantum phase transitions. In 1934, physicist Eugene Wigner made a theoretical prediction based…
What Is Nucleosynthesis? Nucleosynthesis is the creation of new atomic nuclei, the centers of atoms that are made up of protons and neutrons. Nucleosynthesis first…
Material could be used in future quantum computing applications. An international team of physicists led by the University of Minnesota has discovered that a unique…
In a few years, a new generation of quantum simulators could provide insights that would not be possible using simulations on conventional supercomputers. Quantum simulators…
Three years ago, Arthur Ashkin won the Nobel Prize for inventing optical tweezers, which use light in the form of a high-powered laser beam to capture and…
Physicists at Ludwig-Maximilian University in Munich (LMU) and the Max Planck Institute for Quantum Optics (MPQ) have used ultrashort laser pulses to probe the dynamics…
The results open possibilities for studying gravity’s effects on relatively large objects in quantum states. To the human eye, most stationary objects appear to be…
Research led by Kent and the STFC Rutherford Appleton Laboratory has resulted in the discovery of a new rare topological superconductor, LaPt3P. This discovery may be of…
How reproducible are measurements in solid-state physics? New measurements show: An allegedly sensational effect does not exist at all. A single measurement result is not…
Researchers at the University of Gothenburg have observed the absorption of a single electron by a levitated droplet with such a magnification that it is…
Tiny charged electrons and protons which can damage satellites and alter the ozone have revealed some of their mysteries to University of Otago scientists. In…
Approach could be used to create electrically controlled mirrors for art or advanced devices. Researchers have developed a way to dynamically switch the surface of…
Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a…
Glass is one of the most common subjects we see every day, but the detailed structure of this non-metallic and non-liquid material has always been…
The ability to turn on and off a physical process with just one photon is a fundamental building block for quantum photonic technologies. Realizing this…
Power source clusters near rocket engine fuel injectors could create combustion oscillations. Combustion engines can develop high-frequency oscillations, leading to structural damage to the engines…
