MaxwellCouplingMode
MaxwellCouplingMode
Section Hamiltonian
Type integer
Default none
This variable selects the level of light-matter coupling with electromagnetic fields from the Maxwell solver.
Each option defines a coupling Hamiltonian $ H_{int}$.
*Options*:
- none:
No coupling.
- length_gauge_dipole:
Dipole level in length gauge with transverse electric field E(t):
$ H_{int} = -r.E $
The option MaxwellDipoleField should be set to define if $E$ is calculated as an average at evaluated
at the center of mass (by default, dipole coupling with the average electric field will be used).
- multipolar_expansion:
The option MultipoleExpansionTerms selects the terms to be included (electric dipole, electric quadrupole
and/or magnetic dipole).
- velocity_gauge_dipole:
Coupling at dipole level in velocity gauge with transverse vector potential A(t).
$ H_{int} = 1/2m (2 A(t).p + A^2(t)) $
The option MaxwellDipoleField should be set.
- full_minimal_coupling:
Full vector potential A(r,t) coupled to the momentum.
$ H_{int} = 1/2m (2 A(r,t).p + A^2(r,t)) $
