Impact of disorder and phonons on the Hubbard bands of Mott insulators in strong electric fields

The data stored in this repository are a mixture of raw and post-processed ones.

They are sorted by 'figures', i.e. for the figures they have been used to create:

in particular, the resulting publication is available at https://doi.org/10.1103/PhysRevB.109.045119.

The files containing the Green's function ('Green.dat') and various self-energies (electron-phonon, electronic)

are stored (in columns) in the following way:

frequency   Re(X^{R})   Im(X^{R})   Re(X^{K})   Im(X^{K})

and contain only the time-averaged component (l=0) of the Wigner-represented object (X, in this case).

To obtain the Floquet matrix to initialise the code it will be sufficient to write a script that

shifts the 00-entry stored in this files to recreate the diagonal matrix elements of the full matrix.

In the case of a dc field, in fact, the matrices are diagonal by construction (it can be analytically

shown for the local Green's function (gauge invariant one) and the self-energy follows due to the

DMFT approximation.

The data contained in "Par_vec.dat" are the fitting parameters needed for initialise the AMEA solver.
