Dynamical Control of Quantum Heat Engines Using Exceptional Points
J. -W. Zhang, J. -Q. Zhang, G. -Y. Ding +11
A quantum thermal machine is an open quantum system coupled to hot and cold thermal baths. Thus, its dynamics can be well understood using the concepts and tools from non-Hermitian…
Detection of DC electric forces with zeptonewton sensitivity by single-ion phonon laser
Ya-Qi Wei, Ying-Zheng Wang, Zhi-Chao Liu +6
Detecting extremely small forces helps exploring new physics quantitatively. Here we demonstrate that the phonon laser made of a single trapped Ca ion behaves as an ex…
Phonon-laser ultrasensitive force sensor
Zhichao Liu, Yaqi Wei, Liang Chen +4
Developing nano-mechanical oscillators for ultrasensitive force detection is of great importance in exploring science. We report our achievement of ultrasensitive detection of the…
Topological optomechanical amplifier with synthetic -symmetry
Jian-Qi Zhang, Jing-Xin Liu, Hui-Lai Zhang +6
We propose how to achieve synthetic symmetry in optomechanics without using any active medium. We find that harnessing the Stokes process in such a system can lead t…
Optimal joint measurements of complementary observables by a single trapped ion
T. P. Xiong, L. L. Yan, Z. H. Ma +5
The uncertainty relations, pioneered by Werner Heisenberg nearly 90 years ago, set a fundamental limitation on the joint measurability of complementary observables. This limitation…
Exploring the quantum critical behaviour in a driven Tavis-Cummings circuit
M. Feng, Y. P. Zhong, T. Liu +4
Quantum phase transitions play an important role in many-body systems and have been a research focus in conventional condensed matter physics over the past few decades. Artificial…
