    "abstract": "The dynamics of two dimensional (2D) vortex fluctuations are investigated\nthrough simulations of the 2D Coulomb gas model in which vortices are\nrepresented by soft disks with logarithmic interactions. The simulations\ntrongly support a recent suggestion that 2D vortex fluctuations obey an\nintrinsic anomalous dynamics manifested in a long range 1/t-tail in the vortex\ncorrelations. A new non-linear IV-exponent a, which is different from the\ncommonly used AHNS exponent, a_AHNS and is given by a = 2a_AHNS - 3, is\nconfirmed by the simulations. The results are discussed in the context of\nearlier simulations, experiments and a phenomenological description.",
