System parameters

The system parameters specify the $N$ quantum states ${\left\vert i \right>}$ and matrix elements of the Hamiltonian $H_{i,j}$.

• NumStates $<$ $N$ $>$
  Acceptable Values: positive integers
  Default Value: 0
  Description: Specifies the number of quantum states [required]
  Example line(s):
  NumStates=2
  
• Hamiltonian $<$ $H_S+H_{ren}$ $>$
  Acceptable Values: $N\times N$ real values
  Default Value: None
  Description: Specifies the system Hamiltonian. Note that the renormalization term must be included here
  Example line(s):
  Hamiltonian:
  0 ,100.0
  100.0,20.00
  
• InitialDensityMatrix $<$ $\rho(0)$ $>$
  Acceptable Values: $N\times N$ real or complex values
  Default Value: None
  Description: Specifies the initial values of the density matrix. The initial density matrix must be positive definite.
  Example line(s):
  InitialDensityMatrix:
  (0.5,0.0),(0.2,0.1)
  (0.2,-0.1),(0.5,0.0)
  
• HamiltonianEigenvalues $<$ $\epsilon_i$ $>$
  Acceptable Values: $N$ real values
  Default Value: None
  Description: Eigenvalues of system Hamiltonian $H_S$ [required for TimeLocal=1].
  Example line(s):
  HamiltonianEigenvalues:
  -90.49875621,110.49875621
  
• HamiltonianEigenvectors $<$ $\widetilde{{\left\vert \epsilon_i \right>}}$ $>$
  Acceptable Values: $N\times N$ real values
  Default Value: None
  Description: Orthonormal eigenvectors of system Hamiltonian $H_S$ [required for TimeLocal=1].
  Example line(s):
  HamiltonianEigenvectors:
  -0.74145253,0.67100532
  0.67100532,0.74145253
