Experimentation and largest-ever Quantum Simulation of a Disordered system explain Quantum Many-Particle problem

Figure illustrates puddles of localized quasi-condensates found using a quantum Monte Carlo simulation of trapped atoms in a disordered lattice. Individual puddles, consisting of 10-20 particles each, are incoherent relative to each other. The Bose glass is composed of these puddle-like structures. Credit: Ushnish Ray, University of Illinois

Using some of the largest supercomputers available, physics researchers from the University of Illinois at Urbana-Champaign have produced one of the largest simulations ever to help explain one of physics most daunting problems. “This result was a fantastic collaboration between theory and experiment,” explained Prof. Brian DeMarco. “One of the grandest and most impactful frontiers of physics is the quantum many-particle problem...

Shining lasers at superconductors can make them work at higher temperatures, suggests new findings from an international team of scientists including the University of Bath. Superconductors conduct electricity without power loss and produce strong magnetic fields, used in medical scanners, super-fast electronic circuits and in Maglev trains with superconducting magnets to allow train levitation over tracks, eliminating friction.

Currently superconductors only work at very low temperatures, requiring liquid nitrogen or helium to maintain their temperature...
