Extremely short, configurable "femtosecond" pulses of light demonstrated by an international team could lead to future computers that run up to 100,000 times...
A holmium (Ho) and a iron (Fe) atom placed on a MgO substrate are the components for the world's smallest memory device. Ho is used as a storage medium and Fe as a sensor were. The magnetism of the...

The idealized picture of space and time in general relativity assigns an ideal clock to each point in space, which tick evenly without being influenced by the nearby clocks. However, when quantum mechanical and gravitational effects are taken into...
Researchers have created the world's first time crystal, an exotic state of matter that combines the rigidity of an ordinary crystal with a regular rhythm in time.Credit: E. Edwards/JQI
Salt, snowflakes and diamonds are all crystals, meaning their atoms are...
A proposed diamond probe stimulates magnetic moments (aligned electrons) in the material being studied, which then act upon the magnetic field of the probe itself and thus can be measured. Credit: Michael Flatte, University of Iowa

From compasses used in ancient overseas navigation to electrical motors, sensors, and actuators in cars, magnetic materials have been a mainstay throughout human history. In addition, almost all information that exists in contemporary society is recorded in magnetic media,...

The recent detection of gravitation waves (GW) from the merger of two black holes of about...
Researchers at QuTech have built an on-chip microwave laser based on a fundamental aspect of superconductivity, the AC Josephson effect. The device is made from a single nanoscale Josephson junction strongly coupled to a superconducting cavity. When a small...
A mystery concerning the structure of protons is a step closer to being solved, thanks to a seven-year experiment led by researchers at MIT. Credit: Christine Daniloff/MIT
