Observation of hierarchy of Hilbert space ergodicities in the quantum dynamics of a single spin
Wenquan Liu, Zouwei Pan, Yue Fu +4
Ergodicity, the property that all allowed configurations are explored over time, plays a pivotal role in explaining the equilibrium behavior of classical dynamical systems. Yet, su…
Non-Hermitian non-Abelian topological transition in the S=1 electron spin system of a nitrogen vacancy centre in diamond
Yunhan Wang, Yang Wu, Xiangyu Ye +5
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…
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…
Experimental test of the Jarzynski equality in a single spin-1 system using high-fidelity single-shot readouts
Wenquan Liu, Zhibo Niu, Wei Cheng +5
The Jarzynski equality (JE), which connects the equilibrium free energy with non-equilibrium work statistics, plays a crucial role in quantum thermodynamics. Although practical qua…
Experimental study on the principle of minimal work fluctuations
Wei Cheng, Wenquan Liu, Yang Wu +5
The central quantity in the celebrated quantum Jarzynski equality is , where is work and is the inverse temperature. The impact of quantum randomness on the fluctu…
Long-baseline quantum sensor network as dark matter haloscope
Min Jiang, Taizhou Hong, Dongdong Hu +8
Ultralight dark photons constitute a well-motivated candidate for dark matter. A coherent electromagnetic wave is expected to be induced by dark photons when coupled with Standard-…
