The phrase "theoretical simulations" refers to computer-generated models or simulations that help us understand how things might work or how events might unfold in a hypothetical or imaginary situation. Full definition
Now the full effect has been observed, and it persists even when experimenters jiggle the strength of magnetic or electric fields — a robustness that provides even stronger evidence that the experiment has captured a Majorana, as predicted in careful theoretical simulations by Liu.

The experiment has «eliminated a major uncertainty in theoretical simulations of the chemistry and cooling rate of the first gas clouds,» says Avi Loeb, a theoretical physicist at Harvard University. (sciencemag.org)
By using theoretical simulations, the researchers were able to model states of superionic ice that would be difficult to study experimentally. (sciencedaily.com)
