Broadband measurement of Feibelman's quantum surface response functions
Zeling Chen, Shu Yang, Zetao Xie +8
The Feibelman -parameter, a mesoscopic complement to the local bulk permittivity, describes quantum optical surface responses for interfaces, including nonlocality, spill-in and…

Acoustic higher-order topological insulator from momentum-space nonsymmorphic symmetries
Jinbing Hu, Kai Zhou, Tianle Song +3
Momentum-space nonsymmorphic symmetries, stemming from the projective algebra of synthetic gauge fields, can modify the manifold of the Brillouin zone and lead to a variety of topo…
