pip install -e cyclopeps

-e editable mode is suggested for the package is currently under development

Dependencies

Currently, the only dependency is the python version of CTF.

To Do List

• Function to increase bond dimension of PEPS
• Profile CTF Calculations to see how they scale with number of processors

Known Bugs

• TEBD converges to nearly the correct energies for ITF model

CTF Problems/Questions

• Cannot use -1 as and index
• 1D CTF arrays do not have the attribute len
