Licence: CC BY Related projects: 964770 (Topolight), MR/V023845/1 Description of data: Each txt file containing experimental data has a header describing the dimensions and array shape, numerical data is provided with a separate Readme files. ------------ Folder name Figure2: text files contain experimental data used for Figure 2. The names for panels a-e are coded in the following manner: [panel letter]_1sp_[type of data: EK - emission dispersion, KK - emission in Fourier space, KK_polres - polarisation resolved emission in Fourier space]_[external voltage: 0,1600,1840,1880mV]; f_FWHM_data, f_intensity_data, g_energy_data files contain information about the emission intensity, energy, linewidth, and blueshift depending on the excitation power. Figure3: text files contain experimental and numerical data used for Figure 3. The names for experimental data in panels a-i are coded in the following manner: [panel letter:a-i]_1sp_[type of data: EK - emission dispersion, KK - emission in Fourier space, RS - emission in real space]_[distance between spots in micrometers: 9,11,13]. In files j_GPEsim_RS_TwoSpots_V-V_d=11.0µm and k_GPEsim_KS_TwoSpots_V-V_d=11.0µm we present numerical data for corresponding panels in Figure.3. Separate readme file is provided in the same folder with files description. Text file l_quantum_number provides data for panel l. Figure4: Text files ‘a_’RS, ‘b’_KK, contain experimental data for Figures 4(a,b). Figure5: text files contain experimental data used for Figure 5. The names for experimental data in panels a-h are coded in the following manner: [panel letter:a-h]_2sp_[type of data: KK - emission in Fourier space, RS - emission in real space, KK_inset - polarisation resolved data in Fourier space]_[external voltage: 0,1600,1840,1880mV] Figure6: text files contain numerically simulated data used for Figure 6. Detailed description is provided in a separate Readme file in the same folder. Figure7: text files contain experimental data used for Figure 7. The names for data in panels a-i are coded in the following manner: [panel letter:a-i]_[number of excitation spots: 2sp - two spots, 3sp - three spots]_[type of data: KK - emission in Fourier space, RS - emission in real space, S1 - non-normalised real space distribution of S1 Stokes component]_[excitation polarisation arrangement: HH, HHH, HVH, where H=horizontally polarised, V=vertically polarised].
