Weakly Driven and Finite Detuning Boundary Time Crystals Enabled by Low-Dissipation Dynamical Channels
Xiang Guo, Xiaojun Zhang, Zhihai Wang
Spontaneous breaking of continuous time-translation symmetry in driven-dissipative systems gives rise to boundary time crystals (BTCs), characterized by persistent oscillations sus…
Measurement-induced generation of Schrödinger cat states in cavity QED
Tong Wang, Peng-Fei Wei, Hai-Jun Xing +1
Schrödinger cat states, representing coherent superpositions of macroscopically distinguishable states, are indispensable nonclassical resources for continuous-variable quantum inf…
Bound state in the continuum and dynamics via phase modulation in giant-atom waveguide setups
Ji Qi, Xiaojun Zhang, Honngwei Yu +1
Giant atoms, which couple to a waveguide through multiple spatially separated connection points beyond the dipole approximation, provide a versatile route for quantum information p…
Bound state in the continuum and multiple atom state transfer applications in a waveguide QED setup
Xiang Guo, Xiaojun Zhang, Mingzhu Weng +5
Bound states in the continuum (BICs) have been extensively exploited to enhance light--matter interactions in metamaterials, yet their emergence and utility in multi-atom waveguide…
Quantum state preparation and transfer based on the bound state in the doublon continuum
Xiaojun Zhang, Xiang Guo, Yan Zhang +3
Bound states in the continuum (BICs) have attracted intense interest, yet their many-particle counterparts remain largely unexplored in waveguide quantum electrodynamics. We identi…
Enantiodetection in a cavity QED setup with finite chiral molecules
Xiang Guo, Xiaojun Zhang, Yong Li +1
We investigate enantiodetection for both a single cyclic three-level chiral molecule and finite ensembles of such molecules by monitoring the steady-state intracavity photon number…
Engineering atomic superradiance scaling in cavity QED system with collective and individual emission channels
Ruijin Sun, Xiang Guo, Andreas Ruschhaupt +1
The coherent emission of multiple atoms gives rise to superradiance, a cornerstone phenomenon in quantum optics with wide-ranging applications in quantum information processing and…
Giant emitter magnetometer
Xiaojun Zhang, Xiang Guo, Zhihai Wang
Leveraging the sensitive dependence of a giant atom's radiation rate on its frequency [A. F. Kockum, ., Phys. Rev. A 90, 013837 (2014)], we propose an effective magnetometer…
Controllable superradiance scaling in photonic waveguide
Xiang Guo, Zhihai Wang
We investigate the superradiance of two-level target atoms (TAs) coupled to a photonic waveguide, demonstrating that the scaling of the superradiance strength can be controlled on…
Phase-controlled bound states in giant atom waveguide QED setup
Xiaojun Zhang, Mingjie Zhu, Zhihai Wang
We find the phase-controlled bound state out of the continuum~(BOC) and bound state in the continuum~(BIC) in an artificial giant atom dressed one-dimensional photonic waveguide wh…
