How Does Charge and Elasticity Affect Hamiltonian Dynamics?

In summary, the conversation discusses the development of a Hamiltonian and motion equations for a mass m charged with q, attached to a spring with constant k=mω^2 in an electric field E(t)=E0(t/τ)x since t=0. The equilibrium position is x0 and the deformation is represented by ξ=x-x0. The questions pertain to the inclusion of a magnetic field, assuming time symmetry, and the source of the motion equations (Hamiltonian or Lagrangian). The moderator requests the use of PF LaTeX for equations.

Homework Statement
Not homework exactly :-[
Relevant Equations
H = T + U (I posted an attempt to the solution below)
Let a mass m charged with q, attached to a spring with constant factor k = mω ^2 in an electric field E(t) = E0(t/τ) x since t=0.
(Equilibrium position is x0 and the deformation obeys ξ = x - x0)

What would the hamiltonian and motion equations be in t ≥ 0, in terms of m and ω?? Despise magnetic field.

@pepediaz please provide relevant equations and your attempt at a solution.

2) It is correct to assume time symmetry and so equate this "energy function" to the canonic hamiltonian?
3) Motion equations come from hamiltonian or from lagrangian?

Thanks

But it is okay to have the development in the picture??

No. As I said, you need to use the PF LaTeX feature for equations. I gave you the link to the help page for it.

Is it okay to do it in RuBbEr??

Period

I have no idea what that is, but I assume it's not LaTeX. LaTeX is the only option you have here for posting equations. If you cannot or will not use LaTeX, we cannot help you.
 

Related to How Does Charge and Elasticity Affect Hamiltonian Dynamics?

1. What is the Hamiltonian of this system?

The Hamiltonian of a system is a mathematical function that describes the total energy of the system, taking into account both its kinetic and potential energy. It is denoted by H and is a fundamental concept in classical mechanics.

2. How is the Hamiltonian of a system related to its equations of motion?

The Hamiltonian is related to the equations of motion of a system through Hamilton's equations, which describe how the system's position and momentum change over time. These equations are derived from the Hamiltonian using the principle of least action.

3. Can the Hamiltonian of a system change over time?

Yes, the Hamiltonian of a system can change over time if there are external forces acting on the system or if the system itself is changing, such as in a chemical reaction. In this case, the Hamiltonian is a function of time and the equations of motion may also change accordingly.

4. How does the Hamiltonian of a system differ from the Lagrangian?

The Hamiltonian and the Lagrangian are both mathematical functions that describe a system's energy, but they differ in the variables they use. The Lagrangian is a function of the system's position and velocity, while the Hamiltonian is a function of the system's position and momentum. Additionally, the Hamiltonian includes the potential energy of the system, while the Lagrangian does not.

5. What is the significance of the Hamiltonian in quantum mechanics?

In quantum mechanics, the Hamiltonian is a key operator that represents the total energy of a quantum system. It plays a crucial role in determining the system's wavefunction and predicting the probabilities of different outcomes of a measurement. The Schrödinger equation, which describes the time evolution of a quantum system, is based on the Hamiltonian operator.
