Calculation of the DOS of two spinless fermions on a 1D lattice using many body Green Functions.
Requires python 3.5+, numpy package
IMPORTANT: The following will need to be hard-coded into each file as required.
- Specify the interaction potential between the two fermions.
- Specify the range of omega for which calculations are to be done.
- Specify the number of k values over which calculations will run.
