SUMMARY

The discussion centers on verifying the derivative of the Wigner function for Fock States, specifically the expression $$ \frac{∂^2n}{∂β^n∂(β*)^n} exp(-|β|^2-4|α||β|) $$, where β and α are complex variables. The participant's attempted solution is given as (-2|β|-4|α|)^(2n) exp(-|β|^2-4|α||β|). The participant seeks confirmation of the correctness of their derivative calculation related to the Wigner function.

Homework Statement


Currently I am doing a problem of finding Wigner function for Fock States, while I got this derivative, I found the derivative, but I am not sure my answer is correct. please verify whether my answer is correct or not.

$$ \frac{∂^2n}{∂β^n∂(β*)^n} exp(-|β|^2-4|α||β|) $$

β and α are complex.

Homework Equations

The Attempt at a Solution


My solution is (-2|β|-4|α|)^(2n) exp(-|β|^2-4|α||β|)
 
Thank you, I found the Wigner function for Fock States in a different way. But still I don't know how to solve the differentiation I mentioned above.
