    Undergrad Is the change in energy due to light-shift the same in all levels?

    Thank you.

    Undergrad Is the change in energy due to light-shift the same in all levels?

    Thanks, will the shift be in the same direction, or can it be in different directions?

    Undergrad Is the change in energy due to light-shift the same in all levels?

    Remind me please? In a three level system, with discrete energies E0,E1,E2: would light-shift (Stark shift), applied due to an external electric field, change the values of E1 and E2 by the same \Delta E? Or would \Delta E1 be different from \Delta E2?

    Graduate Why do we get oscillations in Euler's method of integration and what i

    Thanks a lot both! 1) I see why it oscillates with a frequency of 1 step, (-1)^n, so this means you normalized the step size to be Er=1? 2) Silly question perhaps, but can this be written in the form of a sine() than?

    Graduate Why do we get oscillations in Euler's method of integration and what i

    When using Euler's method of integration, applied on a stochastic differential eq. : For example - given d/dt v=−γvΔt+sqrt(ϵ⋅Δt)Γ(t) we loop over v[n+1]=v[n]−γv[n]Δt+sqrt(ϵ⋅Δt)Γn. (where −γv[n] is a force term, can be any force and Γn is some gaussian distributed random variable. ) . Then if...
