Homework Statement



I have a question given to me by my prof that is a time dependent Hamiltonian

H(q,p,t) = g(t)(p2/(2m) + kq2/2)

where f(t) has 2 different forms i need to solve

1) eat 2) cos(gt)

problem is goldstein only covers conserved hamiltonians in chapter 10 for the H-J equations and we have no notes in the class about them. My prof doesn't like to answer questions?

Can someone give me some insight how to deal with the time dependent function?

Homework Equations



H(q, ∂S/∂q , t) + ∂S/∂t = 0 i think... but like i said no material on the time dependance

it's all right i figured it out
 
Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
