Figure 4: Photoinduced emission—pumping power dependence.
(a) Evolution of photoinduced emission spectra in magnetic field. No condensate occurs beyond the range of ν=2±0.15 indicated by the white ticks. The straight white line denotes the image cross-section shown in b (photoinduced emission spectra at fixed temperature of 0.5 K and different photoexcitation powers P (in mW cm−2)). The maxima of the optical transition in σ+ polarization are shifted to a single-energy value. (c) Modification of the non-equilibrium electron system during formation of magnetofermionic condensate.
