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...
