Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have listened to the music of a nearby star, uncovering ...

When a star is born, it doesn’t emerge in isolation. Instead, it forms inside a large, chaotic cloud of gas and dust. Around it, a flat disk of spinning material takes shape. This protoplanetary disk ...

A novel approach that re-examines observational data without relying on prior assumptions, using the framework of lattice QCD ...

By using bilayers of recently-discovered materials known as altermagnets, the researchers developed a tuneable and ...

It can also exist for properties that are harder to imagine, such as angular momentum. This property is divided into spin, which is related to the photon's rotation of the electric field ...

In this module, we introduce the general definition of angular momentum operator based on rotation operator. This general definition allows both orbital and spin angular momentum. We then derive the ...
