Popis:	A quantum heat engine (QHE) with a working substance of two-particle $$ \left(\frac{1}{2},1\right) $$ Heisenberg XXX model with Dzyaloshinskii–Moriya (DM) interaction in the external magnetic field B is studied, and the influences of the DM interaction on the efficiency, work are examined under different coupling strengths. The results show that the QHE can operate and produce positive work and the efficiency on the two magnetic field conditions B1 B2. Moreover, the efficiency can achieve the large value and several interesting effects of the DM interaction on the local work are obtained.
