Re: Mapping of Spinful Fermion to Spinless fermion

Thank you for your comment. I have a detailed explanation regarding the spin ladder mapping on stackecxahnge
( https://physics.stackexchange.com/a/637545/246547 ). If this explanation is correct, I will submit in to the corresponding pull request.

Re: Mapping of Spinful Fermion to Spinless fermion

Hi all. I have solved my problem. To understand this algorithm, we need to look back the Hilbert space on both chain and spin ladder. The general idea is that the local Hilbert space of a site on spin chain is H_{i} = V_{i up} \otimes V_{i down}, where the V_{i up} is the Hilbert space of spin up fe...

Mapping of Spinful Fermion to Spinless fermion

I am writing to ask the physics behind the mapping between spinful fermion and spineless fermion in https://tenpy.readthedocs.io/en/latest/intro/JordanWigner.html . I want to know what is the meaning of " spin-1/2 fermions on a chain as spinless fermions living on a ladder." In this algori...
