Purcell effect and quantum Zeno effect suppressed self-discharging of quantum battery
Da-Wei Liu, Guoqing Tian, Zi-Hao Li +3
Quantum batteries (QB), as an energy storage and transfer device, not only show obvious advantages compared to classical electrochemical batteries, but also have important applicat…
Disorder-Induced Exponential Scaling of Subradiant Decay Rates
Guoqing Tian, Xin-You Lü
Subradiance, a hallmark cooperative phenomenon in waveguide QED, is characterized by a universal power-law scaling of decay rates with system size and underpins many applications i…
Decoherence-free Behaviors of Quantum Emitters in Dissipative Photonic Graphene
Qing-Yang Qiu, Guoqing Tian, Zhi-Guang Lu +2
Achieving decoherence-free quantum state manipulation is a paramount goal in modern quantum technologies. To this end, we demonstrate its implementation in a two-dimensional dissip…
Disorder-Induced Strongly Correlated Photons in Waveguide QED
Guoqing Tian, Li-Li Zheng, Zhi-Ming Zhan +2
Strongly correlated photons play a crucial role in modern quantum technologies. Here, we investigate the probability of generating strongly correlated photons in a chain of N qubit…
Topological Quantum Batteries
Zhi-Guang Lu, Guoqing Tian, Xin-You Lü +1
We propose an innovative design for quantum batteries (QBs) that involves coupling two-level systems to a topological photonic waveguide. Employing the resolvent method, we analyti…
Power-Law-Exponential Interaction Induced Quantum Spiral Phases
Guoqing Tian, Ying Wu, Xin-You Lü
We theoretically predict a kind of power-law-exponential (PLE) dipole-dipole interaction between quantum emitters in a 1D waveguide QED system. This unconventional long-range inter…
