I describe a novel mechanism where the variation of an ω 0 condensate can generate a "spike" in the speed of sound in hadronic matter. An ω 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.
