Valley pseudospin in atomically thin semiconductors has been proposed and pursued as an alternative information carrier to charge.
Atoms and photons interact in free space in one of nature’s most fundamental processes. The dipolar interaction strength between the two systems is determined by fundamental constants, with one of its limiting factors being the mode volume of the propagating photons.
Superconductivity induced by proximity effect is particularly interesting in graphene.
Strong light-matter interactions in microcavities have been long known to provide means to alter optical and nonlinear properties of the coupled system. As a result of this interaction, one typically observes the emergence of new polaritonic eigenstates of the coupled system.
