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…
Emergent Universal Quench Dynamics in Randomly Interacting Spin Models
Yuchen Li, Tian-Gang Zhou, Ze Wu +9
Universality often emerges in low-energy equilibrium physics of quantum many-body systems, despite their microscopic complexity and variety. Recently, there has been a growing inte…
Near-Quantum-limited Haloscope Detection of Dark Photon Dark Matter Enhanced by a High-Q Superconducting Cavit
Runqi Kang, Man Jiao, Yu Tong +6
We report new experimental results on the search for dark photons based on a near-quantum-limited haloscope equipped with a superconducting cavity. The loaded quality factor of the…
New Constraints on Exotic Spin-Spin-Velocity-Dependent Interactions with Solid-State Quantum Sensors
Yue Huang, Hang Liang, Man Jiao +8
We report new experimental results on exotic spin-spin-velocity-dependent interactions between electron spins. We designed an elaborate setup that is equipped with two nitrogen-vac…
Measurement of the earth tides with a diamagnetic-levitated micro-oscillator at room temperature
Yingchun Leng, Yiming Chen, Rui Li +7
The precise measurement of the gravity of the earth plays a pivotal role in various fundamental research and application fields. Although a few gravimeters have been reported to ac…
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…
