In-plane optical phonon modes of current-carrying graphene
Mohsen Sabbaghi, Tobias Stauber, Hyun-Woo Lee +2
In this work, we study the in-plane optical phonon modes of current-carrying single-layer graphene whose coupling to the electron gas is strong. Such modes are expected to unde…
Terahertz response of gadolinium gallium garnet (GGG) and gadolinium scandium gallium garnet (SGGG)
Mohsen Sabbaghi, George W. Hanson, Michael Weinert +2
We report the magneto-optical response of Gadolinium Gallium Garnet (GGG) and Gadolinium Scandium Gallium Garnet (SGGG) at frequencies ranging from to $1 \, \…
Inducing and controlling rotation on small objects using photonic topological materials
F. Lindel, G. W. Hanson, M. Antezza +1
Photonic topological insulator plates violate Lorentz reciprocity which leads to a directionality of surface-guided modes. This in-plane directionality can be imprinted via an appl…
The effects of three-dimensional defects on one-way surface plasmon propagation for photonic topological insulators comprised of continuous media
S. Ali Hassani Gangaraj, Andrei Nemilentsau, George W. Hanson
We have investigated the one-way surface plasmon-polariton (SPP) at the interface of a continuous magneto-plasma material and metal. We demonstrated that TM modes inside a continuo…
Notes on photonic topological insulators and scattering-protected edge states - a brief introduction
George W. Hanson, S. Ali Hassani Gangaraj, Andrei Nemilentsau
The topic of photonic topological insulators and scattering-protected edge states bridges concepts from condensed matter physics and electromagnetics, and necessitates understandin…
Anisotropic 2D materials for tunable hyperbolic plasmonics
Andrei Nemilentsau, Tony Low, George Hanson
Motivated by the recent emergence of a new class of anisotropic 2D materials, we examine their electromagnetic modes and demonstrate that a broad class of the materials can host hi…
