How can simple models help us understand experiments?

САЖЕТАК:

Physical models are simplified versions of real systems that allow us to understand and sometimes predict their behaviour. While designing a model we evaluate different mechanisms present in the system and pare it down to a few essential. If designed well, a model gives a better understanding of the measured quantities and fully reveals the interplay of mechanisms behind. In this talk, we will review challenges and modelling work performed for reproducing AFM experiment [1,2], understanding the relationship between the molecular shape of ionic liquids and their behaviour [3], and exploring the phase diagram of the magnetic cubes [4].
