Bogoliubov quasiparticle

In condensed matter physics, a Bogoliubov quasiparticle or bogolon is a quasiparticle that occurs in superconductivity and superfluidity. They are present in BCS theory of superconductors and in Bose–Einstein (BEC) condensates. These quasiparticles are named after Nikolay Bogolyubov who studied the microscopic model of these systems. Theoretically, bogolons originate from a quadratic Hamiltonian that can be diagonalized through a Bogoliubov transformation.

Sometimes these quasiparticles are also called Majorana modes, in analogy with the equations for Majorana fermions.
