InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Tunable plasmon-enhanced second-order optical nonlinearity in transition metal dichalcogenide nanotriangles
F. Karimi, S. Soleimanikahnoj, I. Knezevic
The development of nanomaterials with a large nonlinear susceptibility is essential for nonlinear nanophotonics. We show that transition-metal-dichalcogenide (TMD) nanotriangles ha…
Theory of Exciton Energy Transfer in Carbon Nanotube Composites
A. H. Davoody, F. Karimi, M. S. Arnold +1
We compute the exciton transfer (ET) rate between semiconducting single-wall carbon nanotubes (SWNTs). We show that the main reasons for the wide range of measured ET rates reporte…
Dielectric function and plasmons in graphene: A self-consistent-field calculation within a Markovian master equation formalism
F. Karimi, A. H. Davoody, I. Knezevic
We introduce a method for calculating the dielectric function of nanostructures with an arbitrary band dispersion and Bloch wave functions. The linear response of a dissipative ele…
Basis functions for solution of non-homogeneous wave equation
Sina Khorasani, Farhad Karimi
In this note we extend the Differential Transfer Matrix Method (DTMM) for a second-order linear ordinary differential equation to the complex plane. This is achieved by separation…
Optical Modulation by Conducting Interfaces
Farhad Karimi, Sina Khorasani
We analyze the interaction of a propagating guided electromagnetic wave with a quantum well embedded in a dielectric slab waveguide. First, we design a quantum well based on InAlGa…
Ray-tracing and Interferometry in Schwarzschild Geometry
Farhad Karimi, Sina Khorasani
Here, we investigate the possible optical anisotropy of vacuum due to gravitational field. In doing this, we provide sufficient evidence from direct coordinate integration of the n…
