Magic-angle Bilayer Phononic Graphene
Yuanchen Deng, Mourad Oudich, Nikhil JRK Gerard +3
Thanks to the recent discovery on the magic-angle bilayer graphene, twistronics is quickly becom11 ing a burgeoning field in condensed matter physics. This letter expands the realm…
Acoustic Multifunctional Logic Gates and Amplifier based on Passive Parity-Time Symmetry
Jun Lan, Liwei Wang, Xiaowei Zhang +2
Acoustic analogue computation and signal processing are of great significance, however, it's challenging to realize the acoustic computing devices because of their limitations of s…
Optical Lattices with Higher-order Exceptional Points by Non-Hermitian Coupling
Xingping Zhou, Samit Kumar Gupta, Zhong Huang +5
Exceptional points (EPs) are degeneracies in open wave systems with coalescence of at least two energy levels and their corresponding eigenstates. In higher dimensions, more comple…
Measurement of Surface Acoustic Wave Resonances in Ferroelectric Domains by Microwave Microscopy
Scott R. Johnston, Yongliang Yang, Yong-Tao Cui +7
Surface Acoustic Wave (SAW) resonances were imaged within a closed domain in the ferroelectric LiTaO via scanning Microwave Impedance Microscopy (MIM). The MIM probe is used fo…
