Keyword descriptions
- AMPLITUDE
Type: real
Default: 0.00000000E+000 [Vm-1]
Usage: AMPLITUDE [Vm-1] 1.0E9Description: Electric field amplitude of the monochromatic light.
- BROADENING
Type: real
Default: 2.00000000E-002 [eV]
Usage: BROADENING 0.02Description: Lorentzian broadening applied to the peaks of the Floquet spectral function.
- ENERGY_STEP
Type: real
Default: 1.00000000E-002 [eV]
Usage: ENERGY_STEP 0.01Description: Resolution of the energy E used to compute the spectral function within the energy window.
- ENERGY_WINDOW
Type: real
Default: 1.00000000E+001 [eV]
Usage: ENERGY_WINDOW 5.0Description: Half-width of the energy range, in eV, centred on the Fermi level, over which the Floquet spectral function is evaluated.
- EPS_FLOQUET
Type: real
Default: 1.00000000E-010
Usage: EPS_FLOQUET 1.e-10Description: Threshold on the error due to truncation of the Floquet Hamiltonian. Used to verify that MAX_FLOQUET_INDEX is large enough that truncation errors are small. If negative, the check is removed (not recommended).
- FLOQUET_DOS_FILE_NAME
Type: string
Default: FLOQUET_DOS
Usage: FLOQUET_DOS_FILE_NAME FLOQUET_DOSDescription: File name used for the Floquet spectral function.
- FREQUENCY
Type: real
Default: 1.00000000E+000 [eV]
Usage: FREQUENCY 1.5Description: Frequency of the electric field for Floquet calculations expressed in terms of the energy of a photon in eV.
- MAX_FLOQUET_INDEX
Type: integer
Default: 50
Usage: MAX_FLOQUET_INDEX 50Description: Largest absolute Floquet index up to which Floquet Hamiltonian is truncated. Use a larger value to ensure convergence at higher computational cost and a smaller value for faster computation. EPS_FLOQUET checks to ensure that the error due to truncation is small.
- PHASE_OFFSETS
Type: real[3]
Default: 0.00000000E+000 0.00000000E+000 0.00000000E+000
Usage: PHASE_OFFSETS 0.5 0 0Description: Phase offset of the electric field in the x, y, and z directions given in multiples of π. For linearly polarized light, use 0 0 0 and for left-circularly polarized light travelling in the +z direction use PHASE_OFFSET 0.0 0.5 0
- POLARISATION
Type: real[3]
Default: 0.00000000E+000 0.00000000E+000 1.00000000E+000
Usage: POLARISATION 0.0 0.0 1.0Description: Polarisation vector of the input light. The amplitude in each direction is the product of the AMPLITUDE and the POLARISATION vector component. Eg. for light polarized in the x direction, use 1 0 0. For left-circularly polarized light travelling in the +z direction use 1 1 0 and set PHASE_OFFSET 0 0.5 0 for a +π/2 offset
- QUASI_ENERGIES_FILE_NAME
Type: string
Default: QUASI_ENERGIES
Usage: QUASI_ENERGIES_FILE_NAME QUASI_ENERGIESDescription: File name used for the Floquet quasi-energies.
