Topological Metamaterial for Magnetic Resonance Imaging
Siyong Zheng, Maopeng Wu, Zhonghai Chi +14
Magnetic Resonance Imaging (MRI) is crucial in global healthcare, but the traditional receive coils, as a core component of MRI, SNR enhancement is limited due to the optimization…
Non-Hermitian Complex Coupling for Magnetic Resonance Imaging
Zheng Siyong, Wu Maopeng, Chi Zhonghai +4
Strong coupling in wave-based systems often causes level repulsion, leading to mode splitting and reduced response at the target frequency. This problem is pronounced in magnetic r…
Gain/Loss-free Non-Hermitian Metamaterials
Wu Maopeng, Weng Mingze, Chi Zhonghai +6
The ease of using optical gain/loss provides a fertile ground for experimental explorations of non-Hermitian (NH) physics. Without gain/loss, can we realize the NH effect in a Herm…
Observing the nodal-line conversion determined by the relative homotopy
Maopeng Wu, Mingze Weng, Qian Zhao +2
Directly identifying the non-Abelian nodal-line semimetals (NASM) is quite challenging because nodal-line semimetals typically do not possess topologically protected boundary modes…
Evidencing non-Bloch dynamics in temporal topolectrical circuits
Maopeng Wu, Qian Zhao, Lei Kang +7
One of the core concepts from the non-Hermitian skin effect is the extended complex wavevectors (CW) in the generalized Brillouin zone (GBZ), while the origin of CW remains elusive…
Direct observation of energy band attraction effect in non-Hermitian systems
Maopeng Wu, Ruiguang Peng, Jingquan Liu +2
The energy band attraction (EBA) caused by the non-orthogonal eigenvectors is a unique phenomenon in the non-Hermitian (NH) system. However, restricted by the required tight-bindin…
