Quantum mechanical phenomenon in which heat transfer occurs by wave-like motion
In condensed matter physics, second sound is a quantum mechanical phenomenon in which heat transfer occurs by wave-like motion, rather than by the more usual mechanism of diffusion. Its presence leads to a very high thermal conductivity. It is known as "second sound" because the wave motion of entropy and temperature is similar to the propagation of pressure waves in air (sound).[1] The phenomenon of second sound was first described by Lev Landau in 1941.[2]
