Abstract

We investigate the dynamics of subsystem particle number fluctuations in a long-range system with power-law decaying hopping strength and subjected to a local dephasing at every site. We introduce an efficient bond length representation for the four-point correlator, enabling the large-scale simulation of the dynamics of particle number fluctuations from translationally invariant initial states. Our results show that the particle number fluctuation dynamics exhibit one-parameter Family-Vicsek scaling, with superdiffusive scaling exponents for long-range hopping exponent values less than 3/2 and diffusive scaling exponents for values greater or equal to 3/2. Finally, exploiting the bond-length representation, we provide an exact analytical expression for the particle number fluctuations and their scaling exponents in the short-range limit.
