A state that has been perturbed, ie, disturbed slightly. Often, the trick is that if you have a state whose time evolution is required, and a very similar state's time evolution is known, then we can try to model it such that the former is a perturbed state of latter and go ahead and solve it, that is , a small disturbance like electric or magnetic field is imparted to the latter state, which makes it the former state.
Let me be more explicit, a Hamiltonian H can be considered to be made of 2 parts, H = H0 + delta H , where H0 is a known Hamiltonian, and delta H is a disturbance imparted to it, to make it H. And as I said earlier, typically the disturbance is either an electric field or a magnetic field.

What makes physics important in your life?
Physics in our life is more than a course in physics and more than a laundry list of "how things work." In fact, it combines the two, offering a back-and-forth interplay between everyday applications of physics and the concepts needed to understand them."My approach is entirely qualitative," says Professor Wolfson. "I believe you can understand physics, and understand it deeply, without using mathematics."
Why do you need study physics?
To understand Nature and the Universe.
