Geometric similarities and topological phases in surface magnon polaritons
Chen Qian, Jicheng Jin, Thomas Christensen +4
Highly spatially-squeezed polaritons, with propagation momentum significantly larger than free-space modes at the same frequency, enable varied and extreme control over light-matte…

Observation of Gigahertz Topological Valley Hall Effect in Nanoelectromechanical Phononic Crystals
Qicheng Zhang, Daehun Lee, Lu Zheng +8
Topological phononics offers numerous opportunities in manipulating elastic waves that can propagate in solids without being backscattered. Due to the lack of nanoscale imaging too…
