AI Thread Summary

Hamilton's function in the context of statistical physics combines potential and kinetic energy, expressed as H(x,p;e)=sum(for i=1 to N)(p^2/2m+(mw^2)*x^2/2+qex)=E. The challenge lies in determining the phase volume, Г, which is related to the number of oscillators, where Гn=(Г1)^N. To calculate the phase volume, a proper substitution or transformation in the equations is necessary, but the specific method for this replacement is unclear to the participants. Clarification on how to incorporate the field into the calculations is sought, emphasizing the need for a deeper understanding of the microcanonical distribution. The discussion highlights the complexities of statistical mechanics and the importance of precise definitions in Hamiltonian systems.

Homework Statement: An ideal gas, consisting of N harmonic oscillators of mass m and frequency w and charge q, is placed in an external uniform electric field with intensity e. Find the phase volume limited by the energy hypersurface H(x, p; e)=E. Find an expression for the temperature of the oscillator system.

Relevant Equations: H(x, p; e)=E

Hamilton's function in this case is the sum of potential and kinetic energy? But then I don’t remember or don’t understand what to do with e.
I need to find Г, but I don't understand what to do with the field.

H(x,p;e)=sum(for i=1 to N)(p^2/2m+(mw^2)*x^2/2+qex)=E
Гn=(Г1)^N.
But how to calculate the phase volume? what replacement should I make?

Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'

(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
