中文摘要
最近,关于DNA分子体系的拓扑性质引起了各国研究团队的广泛关注。基于我们的工作基础和相关的实验研究进展,本课题采用平均场近似下的Bogoliubov-de Gennes方程结合非平衡格林函数理论,重点研究DNA分子/超导体结构中Majorana零模的物理性质。主要内容包括:(1)研究DNA分子/超导体结构界面处产生Majorana零模的条件和规律;(2)探究双螺旋DNA分子/超导体异质结中Majorana Kramers pair对输运性质的影响,解释相关的实验现象,提出实验上可行的探测Majorana Kramers pair的理论方法;(3)基于双螺旋DNA拓扑超导体提出非阿贝尔编织算符的实现方案,设计编织Majorana零模的拓扑量子器件,揭示其物理本质。本课题的预期研究成果将增进人们对Majorana零模的认识,并可为生物分子介观尺度量子器件的设计提供一定的理论依据。
英文摘要
The topological properties of the deoxyribonucleic acid (DNA) molecule have attracted extensive attrition among different scientific communities in recent years. Based on our previous works and experimental progress, we propose a project to investigate the Majorana zero mode in the in the interface between DNA molecule and superconductor by using the Bogoliubov-de Gennes equation in the mean-field approximation and the Green's function theory. The research includes that: (1) we investigate the condition and law of production of Majorana zero mode in the interface between double-stranded DNA molecule and superconductor, and explore the application of Majorana zero mode in quantum computing; (2) we explore the influence of the Majorana Kramers pair on the transport properties of DNA molecule/superconductor junction and explain recent experiments, and we will design feasible scheme for probing the existence of the Majorana Kramers pair; (3) we investigate a strategy to realize the non-Abelian braidinglike operation on the DNA molecule/superconductor junction and propose a topological quantum device to regulate Majorana zero mode braiding. The accomplishment of this project will improve the understanding of the Majorana zero mode and provide the base for designing biological molecule-based quantum devices in mesoscale.
