This paper introduces a new physical mechanism causing sharpening of interfacial density gradients in the absence of surface tension: thermal gradient-induced interfaces (TGIIF). It shows that stable droplets, bubbles, and planar interfaces can exist without surface tension, challenging our understanding of phase interfaces and supercritical fluids. This mechanism could optimize fuel injection and heat transfer in high-pressure systems.
