    Eigenstate
In summary, an eigenstate is a quantum-mechanical state that corresponds to an eigenvalue of a wave equation. It can be understood as a non-zero state that, when applied on a specific operator, results in itself multiplied by a constant factor. A basic understanding of linear algebra and eigenvalues is helpful in comprehending this concept.

TL;DR Summary
what is eigenstate?
I found this:
Eigenstate: a quantum-mechanical state corresponding to an eigenvalue of a wave equation.

would you please some one explain simply?

Thanks

Hard to explain without some knowledge of your background. Have you studied linear algebra much. Do you know about eigenvalues and eigenvectors in the math context? That's pretty much the same thing.

Given an operator, (for example, the Hamiltonian, or the Schrödinger Equation) an eigenstate is a (non-zero) state that, when applied on the operator, results of itself multiplied by some constant factor (that is known as the eigenvalue).

Related to What is an Eigenstate? Simple Explanation

What is an Eigenstate?

An eigenstate is a quantum state that represents a specific measurable property of a quantum system. It is a state in which the system has a definite value for that property and will always return that value when measured.

What is the significance of eigenstates in quantum mechanics?

Eigenstates are important in quantum mechanics because they provide a way to describe and understand the behavior of quantum systems. They allow us to predict the outcome of measurements and understand the probabilities of different outcomes.

How is an eigenstate different from a superposition state?

An eigenstate is a single, definite state of a quantum system, whereas a superposition state is a combination of multiple eigenstates. In a superposition state, the system is in multiple states at the same time, with each state having a different probability of being observed.

Can an eigenstate change over time?

No, an eigenstate will not change over time. This is because it represents a fixed value for a specific property, and measurements will always return that same value. However, the probability of measuring that state may change if the system is in a superposition state.

How are eigenstates related to eigenvalues?

Eigenstates are associated with eigenvalues, which are the values that are measured when the system is in that state. The eigenvalue represents the physical quantity that is being measured, such as energy or spin. Each eigenstate has a corresponding eigenvalue, and the measurement of the system will always result in that eigenvalue.
