Physicists identify overlooked uncertainty in real-world experiments

To simplify the solving of massive numbers of partial differential equations (PDEs) for computational modeling, new data-driven surrogate models compute the goal property of a solution to PDEs rather than the whole solution. Credits:Image: Joshua Sortino/Unsplash

Technique could efficiently solve partial differential equations for numerous applications

The image depicts an experiment in which heavy particles (illustrated as the moon), cause an interference pattern (a quantum effect), while also bending spacetime. The hanging pendulums depict the measurement of spacetime. The actual experiment is typically performed using Carbon-60, one of the largest known molecules. The UCL calculation indicates that the experiment should also be performed using higher density atoms such as gold. The other two images represent the two experiments proposed by the UCL group, both of which constrain any theory where spacetime is treated classically. One is the weighing of a mass, the other is an interference experiment.

While errors are normally hard to spot in quantum devices, researchers have shown that, with careful control, some errors can cause atoms to glow. Researchers used this capability to execute a quantum simulation using an array of atoms and a laser beam, as shown in this artist's concept. The experiment showed that they could discard the glowing, erroneous atoms and make the quantum simulation run more efficiently.

An artist's conceptual rendering of antihydrogen atoms falling out the bottom of the magnetic trap of the ALPHA-g apparatus. As the antihydrogen atoms escape, they touch the chamber walls and annihilate. Most of the annihilations occur beneath the chamber, showing that gravity is pulling the antihydrogen down. The rotating magnetic field lines in the animation represent the invisible influence of the magnetic field on the antihydrogen. The magnetic field does not rotate in the actual experiment.
