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…
Experimental test of the Crooks fluctuation theorem in a single nuclear spin
Wei Cheng, Wenquan Liu, Zhibo Niu +3
We experimentally test the Crooks fluctuation theorem in a quantum spin system. Our results show that the Crooks fluctuation theorem is valid for different speeds of the nonequilib…
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…
