用Majorana-库珀对盒阵列模拟具有键定向相互作用的物质的奇异相

Simulating exotic phases of matter with bond-directed interactions with arrays of Majorana-Cooper pair boxes

A. M. Tsvelik

摘要:

研究表明,由金属纳米线连接的马约拉纳-库珀对盒网络可以模拟物质的各种奇异态。在这个模拟中,Majorana-Cooper盒扮演有效自旋S=1/2的角色,金属连接产生Kondo屏蔽和Ruderman-Kittel-Kasuya-Yosida(RKKY)相互作用。取决于什么占主导地位-无论是近藤效应或RKKY交换,一个将有一个有效的自旋模型或近藤晶格。奇异的stets列表包括著名的六角Kitaev模型,该模型的Kondo晶格和各种三自旋相互作用的自旋模型的推广。特别着重讨论了Kondo格的情形。

英文摘要:

It is suggested that networks of Majorana-Cooper pair boxes connected by metallic nanowires can simulate various exotic states of matter. In this simulations Majorana-Cooper boxes play the role of effective spins S=1/2 and the metallic connections generate the Kondo screening and the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction. Depending on what prevails - whether it is the Kondo effect or the RKKY exchange, one will have either an effective spin model or a Kondo lattice. The list of exotic stets includes the famous hexagonal Kitaev model, a generalization of this model for a Kondo lattice and various spin models with three-spin interactions. A special emphasize is made on the discussion of the Kondo lattice scaenario.
