Dear Sir
I can not find the ground state eigenfunction for the code Bosehubbardstatics.py. Can you please mention how to obtain the ground state wavefunction
Can you specify what you expect the ground state function should look like in terms of the format? And I am not sure if you managed to run the example and have some output?
Sincerely,
Daniel
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Dear Sir
Thank you for the reply. Actually, I need to calculate the fidelity which
is $\lim_{(t-\tilde{t})\to0}\frac{-2ln|\langle \psi(t) | \psi(\tilde{t})
\rangle|}{(t-\tilde{t})^2}$. Please suggest me the best way to calculate
this

I attached you a modified example of our Bose-Hubbard statics. In fact, you never need to know the wave function for the ground states, you just need the distance between the two.
I made two changes:
1) Add the ground state as observable written to a file.
2) Add a overlap measure to all previously simulated ground states. (You cannot run in parallel anymore with this setup.)
From there, you should be able to calculate your observable. For the overlap measure, I get the following matrix

Dear Sir
I forgot to mention one thing that t and $\tilde{t}$ are hoppings

Hi Sayan,
I attached you a modified example of our Bose-Hubbard statics. In fact, you never need to know the wave function for the ground states, you just need the distance between the two.
I made two changes:
1) Add the ground state as observable written to a file.
2) Add a overlap measure to all previously simulated ground states. (You cannot run in parallel anymore with this setup.)
From there, you should be able to calculate your observable. For the overlap measure, I get the following matrix
[[ 0. , 0. , 0. , 0. , 0. ],
[ 0. , 0. , 0. , 0. , 0. ],
[ 0.75025925, 0. , 0. , 0. , 0. ],
[ 0.59226553, 0.82314261, 0. , 0. , 0. ],
[ 0.48926198, 0.73258069, 0.91701332, 0. , 0. ]])
Diagonal elements would be the distance of a ground state with itself (must be 1). The upper triangular does not contain any additional information.
I hope that helps you to continue with your research.
Best regards,
Daniel
P.S. There was still missing the first sub-diagonal due to wrong indexing ...
[[ 0. , 0. , 0. , 0. , 0. ],
[ 0.92428665, 0. , 0. , 0. , 0. ],
[ 0.75025925, 0.93620084, 0. , 0. , 0. ],
[ 0.59226553, 0.82314261, 0.96766714, 0. , 0. ],
[ 0.48926198, 0.73258069, 0.91701332, 0.98748269, 0. ]]
Thank You sir for the reply
