A new way of looking at the physics of black boxes

Published Fri, Dec 11, 2020
Quantum physics seems to challenge concepts about our Universe, leading scientists to propose new perspectives on the functioning of the subatomic world. The cause-and-effect relationships addressed by the Bell violation raised discussions among collaborators from three countries, which gave rise...

Description of glueballs through string theory

Published Fri, Dec 04, 2020
The IIP-UFRN publication was part of the doctorate thesis dissertation of the student Cornélio Rodrigues   String theory is a candidate theory to unify all fundamental forces of nature. At very high energies this theory is expected to replace both the Standard Model of elementary...

Baryons, mesons, ... Glueballs?

Published Mon, Nov 30, 2020
Quantum chromodynamics (QCD) is our current fundamental theory of strong interactions. It is precisely these interactions that are behind the force binding protons and neutrons in the atomic nuclei. Fundamental particles of quantum chromodynamics are quarks and gluons. Quarks and antiquarks join...

Electrical detection of Majorana fermions

Published Thu, Nov 26, 2020
Proposed in 2006 by Alexei Kitaev, the Kitaev spin liquid theory proposes the existence of a type of Majorana fermion particle inside it. Once manipulation is possible, a topological quantum computer could be built. This possibility has attracted the attention of experts because of recent...
