A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before ...

Researchers use circularly polarized light to control the direction of exciton polaritons in 2D semiconductors, enabling new ...

Memory technology has evolved quickly in recent years, driven by the need to improve on traditional systems. One promising candidate, Magnetoresistive Random Access Memory (MRAM), is gaining attention ...

Researchers reveal magnetic graphene supports quantum spin Hall states at zero field—paving the way for quantum spintronics.

Nearly 50 years ago, physicists floated a bold idea: our universe might be stuck in a false vacuum. This state feels stable, ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

When a magnetic field is applied to a quantum system, particle spins typically align with or against the field. This well-known effect, known as spin polarization, leads to observable phenomena ...

And that’s exactly what happened, at least some of the time. When the young sharks were exposed to the magnetic field of the place they were caught, off Florida’s Gulf Coast, they swam in ...

When set spinning, the setup mimics the roiling liquid iron in the Earth’s outer core, which forms electrical currents that generate the magnetic field in a process called a dynamo.

The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from.

Scientists from TU Delft (The Netherlands) have observed quantum spin currents in graphene for the first time without using ...
