Recently, the team of Dr. Li Xiaoping from the School of Physical Science and Technology at Inner Mongolia University achieved a major breakthrough in the field of ferroelectric control of topological quantum states. Their study, titled
“Sliding Ferroelectrics Induced Hybrid-Order Topological Phase Transitions,”
has been published in the top-tier physics journal Physical Review Letters.
Dr. Li Xiaoping is the corresponding author, and Professor Zhang Jianmin from Fujian Normal University is the co-corresponding author.
In the current era of rapid technological advancement, topological materials have become a major focus of global research due to their unconventional physical properties and broad application potential—from quantum computing to next-generation electronic devices.
However, one of the major challenges in the field has been how to realize and effectively control topological quantum states.
In response to this challenge, the team led by Li Xiaoping focused on the layer degree of freedom and proposed a novel mechanism whereby sliding ferroelectricity in two-dimensional bilayer systems can induce layer-resolved topological phase transitions.
This work:
Revolutionizes conventional understanding of topological phases,
Introduces a new theoretical framework for designing topological states through layer degrees of freedom,
Leverages intrinsic sliding ferroelectricity to achieve highly tunable topological phases,
and opens up new possibilities for:
Tailoring topological states across different dimensions,
Innovating quantum device design,
Advancing topological quantum computing.
