Improving the Precision of Optical Metrology by Detecting Fewer Photons
Peng Yin, Wen-Hao Zhang, Liang Xu +13
In optical metrological protocols to measure physical quantities, it is, in principle, always beneficial to increase photon number to improve measurement precision. However, practi…
Universality class and exact phase boundary in the superradiant phase transition
Wei-Feng Zhuang, Bin Geng, Hong-Gang Luo +2
The Dicke model and Rabi model can undergo phase transitions from the normal phase to the superradiant phase at the same boundary, which can be accurately determined using some app…
Angular momentum Josephson effect between two isolated condensates
Wei-Feng Zhuang, Yue-Xin Huang, Guang-Can Guo +1
We demonstrate that the two degenerate energy levels in spin-orbit coupled trapped Bose gases, coupled by a quenched Zeeman field, can be used for angular momentum Josephson effect…
Cavity-mediated oscillating and trapping dynamics in a two-component condensate
Yue-xin Huang, Zhen Zheng, Wei Feng Zhuang +2
Cold atoms in cavity provides a new platform for exploring exotic many-body phases. Here we explore the dynamics of a two-component condensate coupled to a finesse cavity, in which…
Gapped topological Fulde-Ferrell-Larkin-Ovchinnikov superfluids with artificial gauge potential and weak interaction
Yue-Xin Huang, Wei-Feng Zhuang, Zhen Zheng +2
The topological superfluids with Majorana zero modes have not yet been realized in ultracold atoms with Rashba spin-orbit coupling. Here we show that these phases can be realized w…
Active Faraday optical frequency standards
Wei Zhuang, Jingbiao Chen
We propose the mechanism of active Faraday optical clock, and experimentally demonstrate active Faraday optical frequency standards based on 852 nm narrow bandwidth Faraday atomic…
Dual-wavelength active optical clock
Zhichao Xu, Duo Pan, Wei Zhuang +1
We experimentally realize the dual-wavelength active optical clock for the first time. As the Cs cell temperature is kept between 118 and 144 , both the 13…
Lasing and suppressed cavity-pulling effect of Cesium active optical clock
Zhichao Xu, Wei Zhuang, Jingbiao Chen
We experimentally demonstrate the collective emission behavior and suppressed cavity-pulling effect of four-level active optical clock with Cesium atoms. Thermal Cesium atoms in a…
Hanle detection for optical clocks
Xiaogang Zhang, Shengnan Zhang, Duo Pan +4
Considering the strong inhomogeneous spatial polarization and intensity distribution of spontaneous decay fluorescence due to the Hanle effect, we propose and demonstrate a univers…
Active optical clock based on four-level quantum system
Tonggang Zhang, Yanfei Wang, Xiaorun Zang +2
Active optical clock, a new conception of atomic clock, has been proposed recently. In this report, we propose a scheme of active optical clock based on four-level quantum system.…
Active Ion Optical Clock
Wei Zhuang, Tonggang Zhang, Jingbiao Chen
In this paper, we propose a scheme of active ion optical clock with detailed pumping method, lasing states, output power, linewidth and light shift. Using 171Yb+ ions in a Paul Tra…
Multi-threshold second-order phase transition
Wei Zhuang, Deshui Yu, Zhiwen Liu +1
We present a theory of the multi-threshold second-order phase transition, and experimentally demonstrate the multi-threshold second-order phase transition phenomenon. With carefull…
The Linewidth of Ramsey Laser with Bad Cavity
Yang Li, Wei Zhuang, Jinbiao Chen +1
We investigate a new laser scheme by using Ramsey separated-field technique with bad cavity. By studying the linewidth of the stimulated-emission spectrum of this kind of laser ins…
