摘      要：The generalized quantum Monte Carlo algorithm is developed and used to calculate the energy,occupation numbers,and correlations functions of finite FeAs clusters in the two-orbital model at finite *** coding of quantum states made it possible to take into account complex exchange terms between the *** results for the calculation of the thermodynamic characteristics of finite two-dimensional FeAs clusters simulating iron-based superconductors have been *** calculated correlation functions indicate the possibility of the effective attraction of charge carriers.
