Symmetry Analysis of the Non-Hermitian Electro-Optic Effect in Crystals
Sylvain Lannebère, Tatiana G. Rappoport, Tiago A. Morgado +2
Here, we investigate how crystal symmetry tailors the non-Hermitian electro-optic effect arising from the Berry curvature dipole. Specifically, we demonstrate the critical influenc…
Engineering transistor-like optical gain in two-dimensional materials with Berry curvature dipoles
Tatiana G. Rappoport, Tiago A. Morgado, Sylvain Lannebère +1
Semiconductor transistors are essential elements of electronic circuits as they enable, for example, the isolation or amplification of voltage signals. While conventional transisto…
Link between the photonic and electronic topological phases in artificial graphene
Sylvain Lannebère, Mário G. Silveirinha
In recent years the study of topological phases of matter has emerged as a very exciting field of research, both in photonics and in electronics. However, up to now the electronic…
Effective Hamiltonian for electron waves in artificial graphene: A first principles derivation
Sylvain Lannebère, Mário G. Silveirinha
We propose a first principles effective medium formalism to study the propagation of electron waves in semiconductor heterostructures with a zero-band gap. Our theory confirms that…
