非均匀Dzyaloshinskill-Moriya相互作用对量子Ising链热传导行为的影响
Effect of the Non-Uniform Dzyaloshinskii-Moriya Interaction on Heat Conduction of Quantum Ising Chains
摘要
Abstract
Basing on the Lindblad master equation,we study the effect of the staggered,random,and the aperiodic Dzyaloshinskii-Moriya(DM) on the heat conductivity of quantum Ising chains.By calculating the average energy-density profile and the average energy current,the numerical results show that the DM interaction could increase the heat conduc tion of Ising chains for the fixed system size with the three kinds of DM interactions above.But the scaling behaviors of energy current with increasing system size for the Ising chain with staggered,random,Finonacci DM interactions show dif ferently.Therefore,the heat transport behavior of Ising chain could be adjusted by controlling the strength and the forms of the DM interaction.关键词
