Nonreciprocal singularities dominated by the dissipative photon-magnon coupling in non-Hermitian systems
Yongzhang Shi, Chi Zhang, Zhenhui Hao +4
We investigated the magnon-photon coupling in an open cavity magnonic system, which leads to two different nonreciprocal singularities dominated by the dissipative coupling. One ty…
Simultaneous nonreciprocal and ultra-strong coupling in cavity magnonics
Chi Zhang, Zhenhui Hao, Yongzhang Shi +5
We demonstrate the simultaneous realization of nonreciprocal coupling and ultra-strong coupling in cavity magnonics. By replacing a copper cylinder with a yttrium iron garnet cylin…
Quantifying the Dzyaloshinskii-Moriya Interaction Induced by the Bulk Magnetic Asymmetry
Qihan Zhang, Jinghua Liang, Kaiqi Bi +15
A broken interfacial inversion symmetry in ultrathin ferromagnet/heavy metal (FM/HM) bilayers is generally believed to be a prerequisite for accommodating the Dzyaloshinskii-Moriya…
Missing-level statistics in classically chaotic quantum systems with symplectic symmetry
Jiongning Che, Junjie Lu, 2 Xiaodong Zhang +2
We present experimental and theoretical results for the fluctuation properties in the incomplete spectra of quantum systems with symplectic symmetry and a chaotic dynamics in the c…
Nonreciprocal Multi-mode and Indirect Couplings in Cavity Magnonics
Chi Zhang, Chenglong Jia, Yongzhang Shi +4
We investigate the magnon-photon couplings by employing a small magnet within an irregular resonant cavity, which leads to a desirable nonreciprocity with a big isolation ratio. Mo…
Dimer rattling mode induced low thermal conductivity in an excellent acoustic conductor
Ji Qi, Baojuan Dong, Zhe Zhang +19
A solid with larger sound speeds exhibits higher lattice thermal conductivity (k_{lat}). Diamond is a prominent instance where its mean sound speed is 14400 m s-1 and k_{lat} is 23…
Backward magnetostatic surface spin waves in exchange coupled Co/FeNi bilayers
Wenjie Song, Xiansi Wang, Wenfeng Wang Changjun Jiang +2
Propagation of backward magnetostatic surface spin waves (SWs) in exchange coupled Co/FeNi bilayers are studied by using Brillouin light scattering (BLS) technique. Two types of SW…
Nonreciprocal Emergence of Hybridized Magnons in magnetic thin Films
Wenjie Song, Xiansi Wang, Chenglong Jia +4
We investigate the transfer and control of nonreciprocity through magnons themselves in permalloy thin films deposited on surface oxide silicon substrate. Evidences of nonreciproca…
Experimental investigation of the fluctuations in nonchaotic scattering in microwave billiards
Runzu Zhang, Weihua Zhang, Barbara Dietz +2
We report on the experimental investigation of the properties of the eigenvalues and wavefunctions and the fluctuation properties of the scattering matrix of closed and open billia…
Anomalous increasing of the intensity of field dependence optical mode ferromagnetic resonance in the exchange coupled bilayer system
Wenfeng Wang, Lulu Pan, Wenjie Song +2
Acoustic and optical ferromagnetic resonance (FMR) in the interlayer exchange coupled FeNi/Co bilayer have been investigated. In the optical mode, unexpected increasi…
