  In this paper, we introduce a theoretical framework for analyzing the
performance of multi-reconfigurable intelligence surface (RIS) empowered
terahertz (THz) wireless systems subject to turbulence and stochastic beam
misalignment. In more detail, we extract a closed-form expression for the
outage probability that quantifies the joint impact of turbulence and
misalignment as well as the effect of transceivers' hardware imperfections. Our
results highlight the importance of accurately modeling both turbulence and
misalignment when assessing the performance of multi-RIS-empowered THz wireless
systems.
