PERIODIC_EFIELD
Section can be repeated.
References: Souza2002, Umari2002
parameters for finite periodic electric field computed using the Berry phase approach. IMPORTANT: Can only be used in combination with OT. Can not be used in combination with RTP or EMD, e.g. RESTART_RTP has to be .FALSE. when restarting the job. [Edit on GitHub]

- END_FRAME: integer = -1
Usage: END_FRAME -1
Last frame the field is applied. If an end frame is specified, the number of active frames must be a multiple of the number of the given intensity values. (-1: no end) Attention: ignored for eeq [Edit on GitHub]
- INTENSITIES_FILE_NAME: string
Usage: INTENSITIES_FILE_NAME filename
File containting a list of intensities, one per line, in a.u. They are applied sequentially, one per frame. If the number of frames exceeds the number of values, the list is cyclically repeated. Attention: not implemented for eeq. [Edit on GitHub]
- INTENSITY: real = 0.00000000E+000
Usage: INTENSITY 0.001
Intensity of the electric field in a.u, not allowed together with INTENSITY_LIST [Edit on GitHub]
- INTENSITY_LIST: real[ ] = 0.00000000E+000
Usage: INTENSITY_LIST {real} {real} .. {real}
Intensities of the electric field in a.u. They are applied sequentially, one per frame. If the number of frames exceeds the number of values, the list is cyclically repeated. Attention: not implemented for eeq. [Edit on GitHub]
- POLARISATION: real[3] = 0.00000000E+000 0.00000000E+000 1.00000000E+000
Usage: POLARISATION 0.0 0.0 1.0
Polarisation vector of electric field [Edit on GitHub]
- START_FRAME: integer = 0
Usage: START_FRAME 0
First frame the field is applied. (0: first frame) Attention: ignored for eeq [Edit on GitHub]
