Re: QuTip for many-body systems

[Paul Nation]

Not in the form that you wrote.  You would have to rewrite the Hamiltonian in terms of Pauli operators.

Dear all,

Many thanks to you for your nice paper and framework for quantum systems.

I was wondering if I can use the framework to solve many-body systems, in the specific case, utra-cold atoms like this Hamiltonian:

H = ∑Ni = 0 (1/2 ∇i 2 + (xi2 + yi2 +λ zi2)) +∑j<iN V(rj - ri)

I’ve had a quick look at some of papers which are used QuTip for numerical calculation such as:

https://doi.org/10.1103/PhysRevA.93.012106

https://doi.org/10.1103/PhysRevLett.116.237203

and so on. But I think they're different from the Hamiltoinan and my case.

I would appreciate it, if you could guide me a bit.

Regards,

Sajad

Hi Paul,

Thank you for your answer.
it's almost impossible to rewrite the Hamiltonian in terms of Pauli operators.
So, I think the software doesn't appropriate for my aim.

Sincerely,
