The electronic structure of benzene in the presence of a high-intensityhigh-frequency circularly polarized laser supports a middle-of-the-ringelectron localization. Here, the laser polarization coincides with the ringplane of benzene. The high-frequency oscillating electric field createscircular currents centered at each atom with a circle radius equal to themaximum field amplitude of the laser. All six carbons have six such rings. Fora maximum field amplitude of 1.42 {\AA}, which is the carbon-carbon bonddistance, all six dynamic current circles intersect to create a deep vortex inthe middle, which supports a bound state of a pair of electrons. Such statesfor benzene can be realized in experiments using a circularly polarizedXUV-laser in a range of intensities 10^16-10^17 W/cm^2 and frequencies 16 eV to22 eV. Electronic dynamics calculations predict a minimal ionization of benzenewhen the rise-time of the laser pulse is sudden, indicating a possibleexperimental realization of these states characterized by a large cut-off inthe harmonic generation spectra. This stable electronic structure of thelight-dressed benzene is doubly-aromatic due to an extra aromaticity from a D6hsymmetric circular distortion of the{\sigma}-framework while the{\pi}-electrons, with low density in the ring-plane,are least affected.
