Quantum Mollow quadruplet in nonlinear cavity QED - data

Simulations of a fermionic two-level system coupled to a bosonic cavity mode. Each simulation consists of beginning with a ground state density matrix, which is operated on by 2 pulse operators. The resultant density matrix is used to find contributions of eigenfrequencies (\omega) of the Lindblad matrix, which is built up of the input parameters, in the form of complex amplitudes (A). Using \omega s and A s we can find the cavity polarisation in the frequency domain and time domain.

Each data folder contains the result of multiple simulations which take place sequentially.

Each data folder is named according to the simulation parameters used. All simulation parameters are listed in the file "params.txt". For example the folder "e1d0g1" varies pulse 1 over simulation number, using a constant detuning (\delta) of 0 (in units of g) and a value of two-level-cavity coupling strength (g) of 1. In each folder there are the following files:

"out_DMplot.txt"
From row 4 onwards, each row contains the value of the subdiagonal entries of the density matrix which contribute to the final cavity polarisation for each simulation immediately after both pulses have occurred.

"out_params.txt"
List of all parameters used in the set of simulations. More details are in the file itself.

"out_spectrum.txt"
First element of the first row is the number of columns in all other rows. Second row is the values of frequency (in units of g) used. Third row onwards are complex values of cavity polarisation (P(\omega)).

"out_spectrum_params.txt"
Legacy file. Is of use only for older versions of the simulation program.

"out_time.txt"
Log of duration of each section of each simulation. "PULSE" refers to performing a single pulse operator on the density matrix, "POLARISATION" refers to the diagonalisation process followed by the final polarisation calculation, "FULLRUN" refers to the entire simulation.

"out_timedomain.txt"
Same layout as "out_spectrum.txt", but the second row is values of time (in units of g), and the third row is values of cavity polarisation.

"out_wA_xxx.txt"
Each simulation produces one of these files. The simulation index "xxx" indicates the value of E used, based on the parameters used in "out_params.txt". For example in the folder "e1d0g1", in "out_params.txt" the values of P1_E (initial value of pulse 1's electric field amplitude) is 0.001, and P1_E_INC (how much to increase pulse 1's strength by in each simulation) is 0.02. This means for "out_wA_001.txt", pulse 1's strength is 0.001, and for "out_wA_021" the strength of pulse 1 is 0.001 + (21-1) * 0.02 = 0.401. In this example the value of pulse 2's strength is 0.001 for all simulations.
