根据Moriya对DM相互作用的对称性要求，宏观D¯矢量不为0则体系的宏观中心反演对称性应该破缺。另宏观物...
interaction on the decay of discord is not remarkable in the weak-coupling region.However,in the strong-coupling region,the decay of discord is very sensitive to the DM interaction.%通过计算全局量子失协,我们研究了三量子比特与存在Dzyaloshinsky-Moriya (DM)相互作用的XY自旋链耦合下的量子失...
It was discovered in a chiral magnet, MnSi with B20 structure, in 2009 and later confirmed as a common feature of magnetic compounds with Dzyaloshinsky–Moriya interaction (DMI). In this work, we provide fundamental insight into the magnetic properties of skyrmion-hosting materials originating ...

By introducing the Dzyaloshinsky-Moriya(DM) interaction, the Loschmidt Echo(LE) of a quantum system consisting of a central spin and its surrounding environment characterized by an XY spin chain was investigated analytically and numerically. At the critical points of the magnetic field, the LE ...
We report in this work, an analytical study of quantum soliton in 1D Heisenberg spin chains with Dzyaloshinsky-Moriya Interaction (DMI) and Next-Nearest-Neighbor Interactions (NNNI). By means of the time-dependent Hartree approximation and the semi-discrete multiple-scale method, the equation of...
