Qualitons At High Density

TL;DR

This paper explores the behavior of baryons as qualitons, called superqualitons, in the color-flavor-locked phase of QCD superconductors, suggesting they could be excited below the superconducting gap, a novel phenomenon.

Contribution

It introduces the concept of superqualitons as baryons behaving as qualitons in the CFL phase, revealing new possible low-energy excitations.

Findings

Baryons act as qualitons with specific quantum numbers in CFL phase

Superqualitons could be excited below the superconducting gap

Potential for novel low-energy baryonic modes in CFL phase

Abstract

In the color-flavor-locked (CFL) phase of the QCD superconductor we show that baryons behave as qualitons (called "superqualitons") with quantum numbers $B=(1 {\rm mod} 2)/3$, S=1/2 and Y=B. An intriguing possibility implied by this identification is that light baryonic modes in the form of superqualitons could be excited below the (color) superconducting gap in the CFL phase, a novel phenomenon foreign to normal superconductors.
