What is a perturbation and how does it affect a system in equilibrium?

In summary, perturbation is a scientific term that refers to a small change or disturbance in a system. It is important in science because it allows for the study of how systems respond to changes and disturbances, and can help us understand the stability and behavior of complex systems. Examples of perturbation include natural events such as earthquakes, human activities like deforestation, and experimental manipulations in scientific studies. It is used in scientific research to study how systems respond to changes and disturbances, and to test hypotheses about the behavior and stability of complex systems. Depending on the system, perturbation can have a range of consequences, from minor changes to major disruptions or even collapse. It is important for scientists to understand the potential consequences of perturbation in order to make

Perturbation-the ability of an unperturb system to remain the same when a perturb system is added to it. Can't really understand this?

It would be really helpful, if you were able to formulate your questions in a comprehensive manner and your statements in a non-tautological and non-repetitve way.

A perturbation (of a system found in an equilibrium state) is simply a (generally) small interaction to which the object(s) under observation is(are) subject to.

In a quantum mechanical setting, a perturbation is described by a new term added to a Hamiltonian operator whose spectral problem is completely solved.
