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…
