Observation of trapped fractional charge and topological states at disclination defects in higher-order topological insulators
Christopher W. Peterson, Tianhe Li, Wentao Jiang +2
Topological crystalline insulators (TCIs) can exhibit unique, quantized electric phenomena such as fractional electric polarization and boundary-localized fractional charge. This q…
A fractional corner anomaly reveals higher-order topology
Christopher W. Peterson, Tianhe Li, Wladimir A. Benalcazar +2
Spectral measurements of boundary localized in-gap modes are commonly used to identify topological insulators via the bulk-boundary correspondence. This can be extended to high-ord…
Robust temporal pumping in a magneto-mechanical topological insulator
Inbar Hotzen Grinberg, Mao Lin, Cameron Harris +4
The transport of energy through 1-dimensional (1D) waveguiding channels can be affected by sub-wavelength disorder, resulting in undesirable localization and backscattering phenome…
Strong nonreciprocity in modulated resonator chains through synthetic electric and magnetic fields
Christopher W. Peterson, Wladimir A. Benalcazar, Mao Lin +2
We study nonreciprocity in spatiotemporally modulated 1D resonator chains from the perspective of equivalent 2D resonator arrays with a synthetic dimension and transverse synthetic…
