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…

Electric Multipole Moments, Topological Multipole Moment Pumping, and Chiral Hinge States in Crystalline Insulators
Wladimir A. Benalcazar, B. Andrei Bernevig, Taylor L. Hughes
We extend the theory of dipole moments in crystalline insulators to higher multipole moments. In this paper, we expand in great detail the theory presented in Ref. 1, and extend it…
