    I Finding the difference in Helmholtz free energy using thermodynamic integration

    Yeah for a lennard jones fluid, and basically I want to perform a computation of this integration process But I am not able to understand how this integration is performed

    I Finding the difference in Helmholtz free energy using thermodynamic integration

    If there any solved papers or even python simulations to find this please share I understood the process of thermodynamic integration but computationally I want to see how this integration of average of derivative of coupled potential energy is done

    A H-Theorem and Lagrange multipliers

    I am so sorry again, when you mean Galilei boost, where exactly am I supposed to apply galilean transformation? I am really sorry If I come accross as a bit naive I am just not able to see it

    A H-Theorem and Lagrange multipliers

    OK I get what you're trying to say but I am not seeing how this is related to my question

    A H-Theorem and Lagrange multipliers

    so I was studying H theorem from Richard Fitzpartic's site. https://farside.ph.utexas.edu/teaching/plasma/Plasma/node35.html Given H, they consider the following equation and set the constants as I want to understand how they got these particular values for a, b &c can we consider the...

    Physics Choice of specialization for Quantum Chromodynamics PhD?

    The thing is in nuclear physics we study some of the basics of article physics and standard model but it's more concerned with reactors and power plants. in QFT, we mainly focus on scalar field theory and other relate stuff like kelin gordon theory, feynman diagrams etc, without covering QCD and...

    Physics Choice of specialization for Quantum Chromodynamics PhD?

    I am entering into the 2nd year of my masters and I plan to do my phd in quantum chromodynamics. So for my specialization, would it be helpful if I choose nuclear and particle physics or quantum field theory?

    I Other ways of finding expectation value of momentum

    it is not symmetric, but as I said I have already found the expectation value using ehrenfest theorem. just asked for some other ways that is all

    I Other ways of finding expectation value of momentum

    Expectation value of momentum of particle in a box and the wave function is time dependent as well

    I Other ways of finding expectation value of momentum

    Yeah I know there are few methods other than this I only asked because I was solving a problem and solving the integral to find the expectation value was very tedious and long Just wanted to know whether there are other ways of finding it, that is all

    I Other ways of finding expectation value of momentum

    yeah I mentioned the integral method in the OP anything other than this?

    I Other ways of finding expectation value of momentum

    Apart from the usual integral method, are there any other ways to find expectation value of momentum? I know one way is by using ehrenfest theorem, relating it time derivative of expectation value of position operator. Even using the uncertainty principle, we might get it if we know the...

    Expectation value in momentum space

    yeah, thing is I am still learning Latex to use it to type equations here, so It would be difficult to get in the whole proof. I tried uploading the pic of my work but there was some issue yeah I think will try to prove why O(p) will commute

    Expectation value in momentum space

    so from Fourier transform we know that Ψ(r)=1/2πℏ∫φ(p)exp(ipr/ℏ)dp I proved that <p>= ∫φ(p)*pφ(p)dp from <p>=∫Ψ(r)*pΨ(r)dr so will the same hold any operator??

    Are the masses connected in series or to either ends of the spring?
