Demonstration of a quantized microwave quadrupole insulator with topologically protected corner states
Christopher W. Peterson, Wladimir A. Benalcazar, Taylor L. Hughes +1
The modern theory of electric polarization in crystals associates the dipole moment of an insulator with a Berry phase of its electronic ground state [1, 2]. This concept constitut…

Synthetic phonons enable nonreciprocal coupling to arbitrary resonator networks
Christopher W Peterson, Seunghwi Kim, Jennifer T Bernhard +1
Inducing nonreciprocal wave propagation is a fundamental challenge across a wide range of physical systems in electromagnetics, optics, and acoustics. Recent efforts to create nonr…
