Parameter file format

The input file has a few general formatting rules:

1. # at the start of a line specifies a comment.
   All comments have to be on separate lines.
   
2. Empty lines are ignored.
   
3. Scalar parameters are specified using
   Parameter=value
   on one line.
   
4. Vector and matrix parameters are specified using
   VectorParameter:
   value1,value2,value3
   and
   MatrixParameter:
   value11,value12,value13
   value21,value22,value23
   value31,value32,value33
   
5. Complex numbers $a+ib$ are input using (a,b). E.g.
   Parameter=(a,b)
   
6. NumStates and NumCouplingTerms must be specified before any vector or matrix parameters can be input.
   

The following parameters MUST be specified in the input file to run PHI:

• NumStates
• HierarchyTruncation

Although, specifying only those parameters will allow you to only check memory requirements or print a hierarchy. The minimum parameters for an integration calculation are

• OutputFile
• NumStates
• HierarchyTruncation
• Hamiltonian
• InitialDensityMatrix
• Lambda
• Gamma
• Timestep
• Runlength
