Feynman wasn't joking: Modeling quantum dynamics with ground state wavefunctions
Galactic 'hailstorm' in the early universe
Two teams of astronomers led by researchers at the University of Cambridge have looked back nearly 13 billion years, when the Universe was less than 10 percent its present age, to determine how quasars - ...
How the physics of champagne bubbles may help address the world's future energy needs
Uncork a bottle of champagne, and as the pressure of the liquid is abruptly removed, bubbles immediately form and then rapidly begin the process of "coarsening," in which larger bubbles grow at the expense ...
How the hummingbird achieves its aerobatic feats
(Phys.org) —The sight of a tiny hummingbird hovering in front of a flower and then darting to another with lightning speed amazes and delights. But it also leaves watchers with a persistent question: How ...
A piece of the quantum puzzle: High level of controllability needed to explore ideas in quantum simulations
While the Martinis Lab at UC Santa Barbara has been focusing on quantum computation, former postdoctoral fellow Pedram Roushan and several colleagues have been exploring qubits (quantum bits) for quantum ...
Shaking the topological cocktail of success
Graphene is the miracle material of the future. Consisting of a single layer of carbon atoms arranged in a honeycomb lattice, the material is extremely stable, flexible, highly conductive and of particular ...
