Quantum fluctuations of the phi^4 theory kink

This is a lattice simulation of the quantum effects that appear as a correction to the classic kink solution of the phi^4 theory. This fields configurations where generated with a Langevin algorithm with a (1+1)D lattice. The z axis represents the value of the field. At the middle of the video, the quantum noise is switched off to show the classic solution.

Can you explain this? I know a little about Quantum Physics, I've been researching.

Think about space as an infinite number of points distributed evenly in all directions. What quantum theory predicts, and more precisely the quantum theory of fields, is that vacuum will no longer be nothing. Instead in addition to what we define as classical vacuum, we will see little oscillators in each points, and quantum effects will force this oscillators to have a non-zero energy. What u see in this video is a special type of vacuum, called kink, and the correspondent quantum oscillations

Is there a way to tell how many quantum fluctuations are large enough to infinitely expand to create what we call a universe which is equal to zero? A quantum fluctuation expands with a positive and negative form of itself thus canceling itself out and the product will be equal to zero, no different from nothing.
