摘要：
We consider equilibrium fluctuations for a class of totally asymmetric zero-range type interacting particle systems, which is particularly related to q-totally asymmetric simple exclusion processes (q-TASEPs). As a main result, we show that density fluctuation of our process converges to the stationary energy solution of the stochastic Burgers equation. Our proof is based on the second-order Boltzmann-Gibbs principle and a Taylor expansion argument.(c) 2022 Elsevier B.V. All rights reserved.
