Study uses thermodynamics to describe expansion of the universe

The idea that the universe is expanding dates from almost a century ago. It was first put forward by Belgian cosmologist Georges Lemaître (1894–1966) in 1927 and confirmed observationally by American astronomer Edwin Hubble ...

Internet can achieve quantum speed with light saved as sound

Researchers at the University of Copenhagen's Niels Bohr Institute have developed a new way to create quantum memory: A small drum can store data sent with light in its sonic vibrations, and then forward the data with new ...

Saturday Citations: Listening to bird dreams, securing qubits, imagining impossible billiards

It's Saturday, which means that in a universe where the arrow of time moves backward, people have to go to work tomorrow. In such a hypothetical universe, Garfield hates Fridays—tough to imagine. This week, we looked at ...

Searching for new asymmetry between matter and antimatter

Once a particle of matter, always a particle of matter. Or not. Thanks to a quirk of quantum physics, four known particles made up of two different quarks—such as the electrically neutral D meson composed of a charm quark ...

The next-generation triggers for CERN detectors

The experiments at the Large Hadron Collider (LHC) require high-performance event-selection systems—known as "triggers" in particle physics—to filter the flow of data to manageable levels. The triggers pick events with ...

Efficiency boost: Dual light pulses minimize energy for phase transitions

Researchers have explained the mechanisms behind a counterintuitive phenomenon: Making a phase transition effective requires less energy if it is initiated by two pulses of light instead of just one. The energy needed to ...
