Piezoelectricity and valley Chern number in inhomogeneous hexagonal 2D crystals
Habib Rostami, Francisco Guinea, Marco Polini +1
Conversion of mechanical forces to electric signal is possible in non-centrosymmetric materials due to linear piezoelectricity. The extraordinary mechanical properties of two-dimen…

Nonlinear anomalous photocurrents in Weyl semimetals
Habib Rostami, Marco Polini
We study the second-order nonlinear optical response of a Weyl semimetal (WSM), i.e. a three-dimensional metal with linear band touchings acting as point-like sources of Berry curv…
