Enhancement of signal-to-noise ratio at a high-order exceptional point of coherent perfect absorption
Zi-Qi Wang, Yi-Ming Sun, Yao-Dong Hu +4
Exceptional points (EPs) in non-Hermitian systems offer a remarkably strong response to weak perturbations, but the nonorthogonal nature of the corresponding eigenvectors causes no…
Synthetically enhanced sensitivity using higher-order exceptional point and coherent perfect absorption
Yao-Dong Hu, Yi-Pu Wang, Rui-Chang Shen +3
Sensors play a crucial role in advanced apparatuses and it is persistently pursued to improve their sensitivities. Recently, the singularity of a non-Hermitian system, known as the…
Polaromechanics: cavity-magnon polaritons strongly coupled to phonons
Rui-Chang Shen, Jie Li, Yi-Ming Sun +5
Building hybrid quantum systems is a crucial step for realizing multifunctional quantum technologies, quantum information processing, and hybrid quantum networks. A functional hybr…
Kinked linear response from non-Hermitian cold-atom pumping
Fang Qin, Ruizhe Shen, Linhu Li +1
It is well known that non-Hermitian, non-reciprocal systems may harbor exponentially localized skin modes. However, in this work, we find that, generically, non-Hermiticity gives r…
Entangling cavity-magnon polaritons by interacting with phonons
Xuan Zuo, Zhi-Yuan Fan, Hang Qian +2
We show how to entangle two cavity-magnon polaritons (CMPs) formed by two strongly coupled microwave cavity and magnon modes. This is realized by introducing vibration phonons, via…
Proposal for Observing Yang-Lee Criticality in Rydberg Atomic Arrays
Ruizhe Shen, Tianqi Chen, Mohammad Mujahid Aliyu +4
Yang-Lee edge singularities (YLES) are the edges of the partition function zeros of an interacting spin model in the space of complex control parameters. They play an important rol…
Giant spin ensembles in waveguide magnonics
Zi-Qi Wang, Yi-Pu Wang, Jiguang Yao +6
The dipole approximation is usually employed to describe light-matter interactions under ordinary conditions. With the development of artificial atomic systems, `giant atom' physic…
Universal competitive spectral scaling from the critical non-Hermitian skin effect
Fang Qin, Ye Ma, Ruizhe Shen +1
Recently, it was discovered that certain non-Hermitian systems can exhibit qualitative different properties at different system sizes, such as being gapless at small sizes and havi…
High-fidelity realization of the AKLT state on a NISQ-era quantum processor
Tianqi Chen, Ruizhe Shen, Ching Hua Lee +1
The AKLT state is the ground state of an isotropic quantum Heisenberg spin- model. It exhibits an excitation gap and an exponentially decaying correlation function, with fractio…
Mechanical Bistability in Kerr-modified Cavity Magnomechanics
Rui-Chang Shen, Jie Li, Zhi-Yuan Fan +2
Bistable mechanical vibration is observed in a cavity magnomechanical system, which consists of a microwave cavity mode, a magnon mode, and a mechanical vibration mode of a ferrima…
Optical sensing of magnons via the magnetoelastic displacement
Zhi-Yuan Fan, Rui-Chang Shen, Yi-Pu Wang +2
We show how to measure a steady-state magnon population in a magnetostatic mode of a ferromagnet or ferrimagnet, such as yttrium iron garnet. We adopt an optomechanical approach an…
Long-Time Memory and Ternary Logic Gate Using a Multistable Cavity Magnonic System
Rui-Chang Shen, Yi-Pu Wang, Jie Li +3
Multistability is an extraordinary nonlinear property of dynamical systems and can be explored to implement memory and switches. Here we experimentally realize the tristability in…
