How an $\omega_0$ condensate can spike the speed of sound in cold quarkyonic matter

TL;DR

This paper proposes a new mechanism involving an $$ condensate that can cause a sharp increase in the speed of sound in cold quarkyonic matter, potentially explaining observed phenomena in hadronic physics.

Contribution

It introduces a novel mechanism where the variation of an $$ condensate creates a spike in the speed of sound, incorporating the concept of a Quantum Pion Liquid.

Findings

The $$ condensate can induce a spike in the speed of sound.

The appearance of a Quantum Pion Liquid can decrease the speed of sound.

The mechanism explains how the speed of sound can both increase and decrease in hadronic matter.

Abstract

I describe a novel mechanism where the variation of an $\omega_0$ condensate can generate a "spike" in the speed of sound in hadronic matter. An $\omega_0$ condensate naturally increases the speed of sound; the real problem is how to get the speed of sound to decrease. I suggest this can happen through the appearance of a Quantum Pion Liquid.
