Highly frustrated spin systems represent a central and challenging problem incondensed mater physics. To this problem, we introduce an algorithm based onmixed projected entangled pair states (m-PEPS), which is a novel type of tensornetwork. We use the famous Kitaev model on an infinite honeycomb lattice, whichcan be solved exactly, as a benchmark. With very limited parameters and finitescaling, our calculation results are in good agreement with the exact results,indicating the efficiency of our algorithm. After presenting the benchmark, weinvestigate the Kitaev-Heisenberg model, which was proposed to describe theeffective magnetic momentum interaction in iridate Na$_2$IrO$_3$ which may beused to realize the spin liquid phase. However, our calculations suggest thatthe gapless spin liquid phase is not robust at the thermodynamic limit, andthus this phenomenon is very difficult to observe.
