Non-Hermitian topological systems exhibit a range of unique phenomena that are absent in their Hermitian counterparts.

Researchers at Tampere University and their collaborators from Germany and India have experimentally confirmed that angular momentum is conserved when ...

How is it possible for the ISS to stay in orbit? Learn more about the science behind orbiting Earth and more in this NASA ...

But orbital angular momentum also has great potential as an information carrier -- and is significantly more robust," explains Dr. Christian Tusche from the Peter Grünberg Institute (PGI-6) at ...

In February, the Book Review Book Club will read and discuss “Orbital,” by Samantha Harvey. We’ll be chatting about the book on the Book Review podcast that airs on Feb. 28, and we’d love ...

Monopoles of orbital angular momentum (OAM) are a tantalizing prospect for orbitronics because OAM is uniform in all directions. This would mean that information flows could be generated in any ...

Orbital angular momentum has the potential to transfer, manipulate and store information. They are made from the orbital angular momentum of electrons orbiting their atomic nucleus – and the study of ...
