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.

In physics, a perturbed state refers to a system that has been altered or disturbed from its original equilibrium state by an external influence or force. This disruption can lead to changes in the system's behavior or properties as it responds to the perturbation. Studying perturbed states helps in understanding the dynamics and stability of physical systems.

What is the verb phrase of I'll never understand physics.?
"Will understand" is the verb phrase. I'll is a contraction of I and will; never is an adverb.
Were is the verb phrase in the sentence I'll never understand physics?
A verb phrase is the verb and its dependents (objects, complements, and other modifiers), but not the subject or its dependents.The verb phrase in the sentence is "will never understand physics".This is a tricky one because part of the verb (will) is hidden in the contraction "I'll".The subject of the sentence is I.

What is physics and relation of physics with society?
Physics is a science which strives to understand the rules following which the world around us works.

How does a veterinarian use physics?
Veterinarians use physics to understand how x-rays work and how to work safely around them.
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.
When was Solid State Physics Laboratory created?
Solid State Physics Laboratory was created in 1962.

will understand is the verb phrase.never is an adverb
What would happen if physics does not exist?
Without physics, there would be no understanding of how the universe works, no laws governing the behavior of matter and energy, and no scientific framework to explain natural phenomena. Essentially, the fabric of reality as we know it would cease to function and the universe would be a chaotic and unpredictable place.
