Create a hump-like density profile in Fermi-Hubbard model
Hi, I'm trying to create a hump-like density profile in a spinless 1D Fermi-Hubbard model using DMRG engine. To do so I'm using a standard FermiHubbardModel class in TenPy and adding an onsite potential V_i*n_i at each site i=1,...,N, where V_i is the external potential with the Gaussian shape, V(x)...
