Chiral terahertz lasing with Berry curvature dipoles
Amin Hakimi, Kasra Rouhi, Tatiana G. Rappoport +2
Materials with Berry curvature dipoles (BDs) support a non-Hermitian electro-optic (EO) effect that is investigated here for lasing at terahertz (THz) frequencies. Such a system is…
Orbital Hall effect and topology on a two-dimensional triangular lattice: from bulk to edge
Anderson L. R. Barbosa, Luis M. Canonico, Jose H. García +1
We investigate a generalized multi-orbital tight-binding model on a triangular lattice, a system prevalent in a wide range of two-dimensional materials, and particularly relevant f…
Ultrathin films of black phosphorus as suitable platforms for unambiguous observation of the orbital Hall effect
Tarik P. Cysne, Marcio Costa, Marco Buongiorno Nardelli +2
Phosphorene, a monolayer of black phosphorus, is a two-dimensional material that lacks a multivalley structure in the Brillouin zone and has negligible spin-orbit coupling. This ma…
Non-Hermitian Photonic Spin Hall Insulators
Rodrigo P. Câmara, Tatiana G. Rappoport, Mário G. Silveirinha
Photonic platforms invariant under parity (), time-reversal (), and duality () can support topological phases analogous to those found in tim…
