Topological phases and transitions are of fundamental importance in physics, which provide a deep insight into the understanding of materials. Recently, non-Abelian topological tra…
Experimental observation of Dirac exceptional point
Yang Wu, Dongfanghao Zhu, Yunhan Wang +2
The energy level degeneracies, also known as exceptional points (EPs), are crucial for comprehending emerging phenomena in materials and enabling innovative functionalities for dev…
Programmable simulation of high-order exceptional point with a trapped ion
Yue Li, Yang Wu, Yuqi Zhou +9
The nontrivial degeneracies in non-Hermitian systems, exceptional points (EPs), have attracted extensive attention due to intriguing phenomena. Compared with commonly observed seco…
Experimental investigation of coherent ergotropy in a single spin system
Zhibo Niu, Yang Wu, Yunhan Wang +2
Ergotropy is defined as the maximum amount of work that can be extracted through a unitary cyclic evolution. It plays a crucial role in assessing the work capacity of a quantum sys…
Third-order exceptional line in a nitrogen-vacancy spin system
Yang Wu, Yunhan Wang, Xiangyu Ye +6
The exceptional points (EPs) aroused from the non-Hermiticity bring rich phenomena, such as exceptional nodal topologies, unidirectional invisibility, single-mode lasing, sensitivi…
Observation of the Knot Topology of Non-Hermitian Systems in a Single Spin
Yang Wu, Yunhan Wang, Xiangyu Ye +5
The non-Hermiticity of the system gives rise to distinct knot topology that has no Hermitian counterpart. Here, we report a comprehensive study of the knot topology in gapped non-H…
