Title: Flux tubes and the type-I/type-II transition in a superconductor coupled to a superfluid
Authors: Mark G. Alford, Gerald Good

Status: Published Phys. Rev. B, open access

Physicists are fascinated by neutron stars because their dense interior acts as a laboratory for exotic materials beyond what we find on Earth. Today’s paper suggests that flux tubes, which are quantum objects that exist in superconductors, could form bundles inside a neutron star – this unusual behaviour challenges the standard picture we have of terrestrial superconductors.

What do we do?

Astrobites is a daily astrophysical literature journal written by graduate students in astronomy. Our goal is to present one interesting paper per day in a brief format that is accessible to undergraduate students in the physical sciences who are interested in active research.
Why read Astrobites?

Reading a technical paper from an unfamiliar subfield is intimidating. It may not be obvious how the techniques used by the researchers really work or what role the new research plays in answering the bigger questions motivating that field, not to mention the obscure jargon! For most people, it takes years for scientific papers to become meaningful.
Our goal is to solve this problem, one paper at a time. In 5 minutes a day reading Astrobites, you should not only learn about one interesting piece of current work, but also get a peek at the broader picture of research in a new area of astronomy.
