Dear Vald20,
thank you for your message. The calculation of the full spectral density of states of the Hamiltonian is something I started implementing, yet it was not finished yet. In short, the sampling of the full Hilbert space with MPS in a uniform way (equivalent to ED) is required for get_dos, and this point has not been implemented in a robust way yet. For the sake of clarity, I will remove that example from the examples folder, and it will be included later.
There are several examples showing how to compute the spectral dynamical correlatiors in the folder dynamical_correlator, perhaps some of them can be useful for your purpose.
Thanks for bringing up this point!
Best regards, Jose
hi Jose Thanks for your answer. I will try it out!!
Hello. I need help in computing the density of state of a spin chain.
I tried to run the example name: "dos_spin_chain". But I got the following error:
AttributeError: 'Spin_Chain' object has no attribute 'get_dos'
How can I solve this problem?
