Understanding the thermodynamic cost of timekeeping

Clocks are essential building blocks of modern technology, from computers to GPS receivers. They are also essentially engines, irreversibly consuming resources in order to generate accurate ticks. But what resources have ...

Evading the uncertainty principle in quantum physics

The uncertainty principle, first introduced by Werner Heisenberg in the late 1920's, is a fundamental concept of quantum mechanics. In the quantum world, particles like the electrons that power all electrical product can ...

Team directs and measures quantum drum duet

Like conductors of a spooky symphony, researchers at the National Institute of Standards and Technology (NIST) have "entangled" two small mechanical drums and precisely measured their linked quantum properties. Entangled ...

Researchers produce laser pulses with record-breaking intensity

Researchers have demonstrated a record-high laser pulse intensity of over 1023 W/cm2 using the petawatt laser at the Center for Relativistic Laser Science (CoReLS), Institute for Basic Science in the Republic of Korea. It ...

Homing in on the smallest possible laser

At extremely low temperatures, matter often behaves differently than in normal conditions. At temperatures only a few degrees above absolute zero (-273 degrees Celsius), physical particles may give up their independence and ...

Random close packing or jamming of spheres in a container

Scientists at the theoretical institutes, Chinese Academy of Science and Cybermedia Center at Osaka University performed extensive computer simulations to generate and examine random packing of spheres. They show that the ...

New boost in quantum technologies

In an international collaboration, researchers at the University of Stuttgart were able to detect quantum bits in two-dimensional materials for the first time. Nature Materials publishes this research in its May 6, 2021 issue.

Magnetic material breaks super-fast switching record

Researchers at CRANN (The Centre for Research on Adaptive Nanostructures and Nanodevices), and the School of Physics at Trinity College Dublin, today announced that a magnetic material developed at the Centre demonstrates ...

Searching for the supersymmetric bottom quark (and its friends)

When it comes to quarks, those of the third generation (the top and bottom) are certainly the most fascinating and intriguing. Metaphorically, we would classify their social life as quite secluded, as they do not mix much ...
