Swimming upstream: Flux flow reverses for lattice bosons in a magnetic field

(PhysOrg.com) -- Matter in the subatomic realm is, well, a different matter. In the case of strongly correlated phases of matter, one of the most surprising findings has to do with a phenomenon known as the Hall response – an important theoretical and experimental tool for describing emergent charge carriers in strongly correlated systems, examples of which include high temperature superconductors and the quantum Hall effect.

Earth's Magnetic Field Reversals Illuminated By Lava Flows Study

Academics / General Science : Science Daily (6 years ago)

Earth's north magnetic pole is shifting and weakening. Ancient lava flows are guiding a better understanding of what generates and controls the Earth's magnetic field -- and what may drive it to occasionally reverse direction. Curre... Read Post

Eye on ionization: Visualizing and controlling bound electron dynamics in strong laser fields

Academics / General Science : Physorg Features (3 years ago)

(PhysOrg.com) -- Subatomic events can be remarkably counterintuitive. Such is the case in theoretical physics when, under certain specific conditions, atoms exposed to intense infrared laser pulses remain stable rather than undergoi... Read Post

Missing link in metal physics explains Earth's magnetic field

Academics / General Science : Science Daily (17 hours ago)

Earth's magnetic field shields the life on our planet's surface from cosmic rays. It is generated by turbulent motions of liquid iron in Earth's core. Iron is a metal, which means it can easily conduct a flow of electrons. New findi... Read Post
