tenpy.algorithms.dmrg.chi_list(chi_max, dchi=20, nsweeps=20)[source]¶ Compute a ‘ramping-up’ chi_list.
The resulting chi_list allows to increases chi by dchi every nsweeps sweeps up to a given maximal chi_max.
- Parameters
- chi_maxint
Final value for the bond dimension.
- dchi :int
Step size how to increase chi
- nsweepsint
Step size for sweeps
- Returns
- chi_listdict
To be used as chi_list parameter for DMRG, see
run(). Keys increase by nsweeps, values by dchi, until a maximum of chi_max is reached.
