    "abstract": "Production and analysis of non-Gaussian radiation fields has evinced a lot of\nattention recently. Simplest way of generating such non-Gaussians is through\nadding (subtracting) photons to Gaussian fields. Interestingly, when photons\nare added to classical Gaussian fields, the resulting states exhibit {\\em\nnon-classicality}. Two important classical Gaussian radiation fields are\ncoherent and thermal states. Here, we study the non-classical features of such\nstates when photons are added to them. Non-classicality of these states shows\nup in the negativity of the Wigner function. We also work out the {\\em\nentanglement potential}, a recently proposed measure of non-classicality for\nthese states. Our analysis reveals that photon added coherent states are\nnon-classical for all seed beam intensities; their non-classicality increases\nwith the addition of more number of photons. Thermal state exhibits\nnon-classicality at all temperatures, when a photon is added; lower the\ntemperature, higher is their non-classicality.",
