Parameters in NuclearToolkit

Here is the summary of optional parameters, which can be specified by users like this:

make_chiEFTint(;fn_params="your_parameter_file.jl")

If you do not specify the optional argument fn_params, the pacakege tries to read optional_parameters.jl in the current path.

• For ChiEFTint
  • n_mesh::Int64, number of momentum mesh
  • pmax_fm::Float64, maximum pmax in fm$^{-1}$
  • emax::Int64, emax quanta
  • Nnmax::Int64, Nnmax quanta
  • chi_order::Int64, order of chiral EFT potenteial (0:LO 1:NLO 2:NNLO 3:N3LO 4:N4LO)
  • calc_NN::Bool, calculate NN part
  • calc_3N::Bool, calculate eff2n (2n3n) part
  • coulomb::Bool, calculate Coulomb term
  • calc_EperA::Bool, calculate E/A
  • hw::Float64 hbar omega in MeV
  • srg::Bool, SRG transformation (NN-only)
  • srg_lambda::Float64, resolution scale for SRG in $fm^{-1}$
  • tbme_fmt::String file format of matrix-elements of free-space interaction. "snt" or "snt.bin" is supported
  • fn_tbme::String file name of output interaction
  • pottype::String potential type (em500n3lo,emn500n3lo,emn500n4lo)
  • kF::Float64 Fermi momentum for 2n3n in fm$^{-1}$

  • maxnormOmega::Float64 tol for norm of IMSRG generator
  • denominatorDelta::Float64 denominator delta for multi-shell interaction
  • BetaCM::Float64 beta for center-of-mass correction
  • magnusamethod::String specifying IMSRG solver ("" or "split" => multi-step splitting (as a default), "no-split" or "NS"=> no-splitting)
