Thermal Emission and Albedo Spectra of Super Earths with Flat Transmission Spectra
, 2015 Planets larger than Earth and smaller than Neptune are some of the most numerous in the galaxy, but observational efforts to understand this population have proved challenging because optically thick clouds or hazes at high altitudes obscure molecular ...

Self-similar transmission properties of aperiodic Cantor potentials in gapped graphene
, 2015 We investigate the transmission properties of quasiperiodic or aperiodic structures based on graphene arranged according to the Cantor sequence. In particular, we have found self-similar behaviour in the transmission spectra, and most importantly, we ...
