Magnetic avalanche triggered by quantum effects: 'Barkhausen noise' detected for first time

Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region of the material but are not ...

Fukushima fallout transport longevity revealed by North Pacific ocean circulation patterns

Fukushima is now notorious for the nuclear disaster that took place in March 2011, the second worst of its kind after the Chernobyl catastrophe of 1986. An earthquake-triggered tsunami off the Japanese coast damaged backup ...

Plasma fusion: Adding just enough fuel to the fire

How much fuel can we add to the fire while still maintaining control? Metaphorically speaking, that's the question one team at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has been asking themselves ...

A method to compute the Rényi entanglement entropy in auxiliary-field quantum Monte Carlo simulations

Entanglement is a widely studied quantum physics phenomenon, in which two particles become linked in such a way that the state of one affects the state of another, irrespective of the distance between them. When studying ...

Scientists confirm that methane-processing microbes produce a fossil record

Communities of microbes that live in ocean sediments can consume methane. In oxygen-deprived sediments these microbes form clusters, called aggregates, that can have deposits of silica on their surfaces. It is not clear if ...
