Extremely short, intense light flashes are in high demand to investigate atoms, molecules and new materials. Free-electron lasers (FELs) produce these flashes. But around the world, beam time available at large-scale user facilities is in short supply, and waiting times are long.
The vast majority of modern quantum technologies—from quantum cryptography to the quantum internet to the quantum computer—rely on one essential element: the transmission of photons. Two qubits (two atoms, for example) exchange information: One qubit emits a photon, and the other qubit absorbs it.
Physicists at the University of Oxford have helped confirm that one of the strangest phenomena in physics—quantum entanglement—occurs even among some of the heaviest and most fleeting particles ever created. The discovery, made using the world’s most powerful particle collider at CERN, has been published in Physical Review Letters.
In 1931, physicist Hans Bethe predicted that, in certain one-dimensional quantum systems, particles can bind together to form multi-particle states known as Bethe strings. Unlike ordinary molecules, which are held together by chemical bonds, Bethe strings arise purely from interactions between particles and exist only in one dimension. For decades, Bethe strings remained primarily a theoretical concept.
Thermoelectric materials can directly convert heat into electricity, making them promising for recovering waste heat from factories, vehicles and other sources. They can also transport heat when an electric current is applied through a phenomenon known as the Peltier effect. These properties have attracted considerable interest in energy-saving technologies and thermal management.
