What happens when you explode a chemical bond?

Light-induced breakage of chemical bonds can lead to damage in the body and environment, but techniques for studying this photochemical reaction have been limited to before and after snapshots. With attosecond lasers and a technique to probe the energy states of photoexcited molecules, chemists have made a movie of the process preceding breakup. The technique will help study biological molecules that absorb light without breaking bonds, such as rhodopsin in the retina.

New virtual laboratory for merging neutron stars

For the first time, a high-performance computer will make it possible to simulate gravitational waves, magnetic fields and neutrino physics of neutron stars simultaneously.

The best of both worlds: How to solve real problems on modern quantum computers

Researchers have developed hybrid algorithms to run on size-limited quantum machines and have demonstrated them for practical applications.

A connection between quantum correlations and spacetime geometry

Researchers of the Academy explore the consequences of locality for measurements distributed in spacetime. Their article has now been published in the Nature journal Quantum Information.

Coupling qubits to sound in a multimode cavity

In a recent study, researchers at the University of Colorado have resolved phonon Fock states in the spectrum of a superconducting qubit coupled to a multimode acoustic cavity. Fock states (or number states) are quantum states with a clearly defined number of particles. These states play a crucial part in the second quantization formulation of quantum mechanics.

Midge swarms show mechanical properties, behave as a viscoelastic material

A team of researchers from Stanford University and Rothamsted Research, has found that midge swarms have some types of mechanical properties and also respond to a stimulus at times as a viscoelastic. In their paper published in the journal Science Advances, the group describes their study of swarm behavior in a species of midges and what they found.

Rediscovering Saskatchewan's scientific heritage

Gathered together from every corner of the University of Saskatchewan (USask) Department of Physics and Engineering Physics, the unique collection of scientific artifacts fills two rooms in the Physics Building.

Light may increase magnetic memory speeds 1000 times, decrease electricity consumption

Internet searches, decade-old emails and on-demand video offerings help contribute to electricity consumption by America's server farms and data centers amounting to more than 2 percent of the country's annual total.

Theory explains ferromagnetic superconductor behavior

Researchers from France and Russia have offered a theoretical explanation for the behavior of a recently discovered material combining superconducting and ferromagnetic properties. The new theoretical model also predicts so far unobserved effects in materials of this kind. The study was published in Physical Review Letters.

Discovered: A new way to measure the stability of next-generation magnetic fusion devices

Scientists seeking to bring to Earth the fusion that powers the sun and stars must control the hot, charged plasma—the state of matter composed of free-floating electrons and atomic nuclei, or ions—that fuels fusion reactions. For scientists who confine the plasma in magnetic fields, a key task calls for mapping the shape of the fields, a process known as measuring the equilibrium, or stability, of the plasma. At the U.S.
