Tunable giant Purcell enhancement of quantum light emitters by means of acoustic graphene plasmons
Justin Gruber, Mahtab A. Khan, Dirk R. Englund +1
Inspired by the remarkable ability of plasmons to boost radiative emission rates, we propose leveraging acoustic graphene plasmons (AGPs) to realize tunable, giant Purcell enhancem…
Emergent Superfluidity of Hard-Core Excitons in Single-Layer Breathing-Kagome NbTeCl
Mahtab A. Khan, Michael N. Leuenberger
We develop a microscopic theory of superfluidity for hard-core dark excitons on the triangular lattice by mapping the large- Bose--Hubbard model to an effective XXZ spin-$\frac{…
Er:AlO for Telecom-Band Photonics: Electronic Structure and Optical Properties
Mahtab A. Khan, Jayden D. Craft, Hari P. Paudel +3
Er-doped AlO is a promising host for telecom-band integrated photonics. Here we combine ab initio calculations with a symmetry-resolved analysis to elucidate substitutional…
Multiferroic Dark Excitonic Mott Insulator in the Breathing-Kagome Lattice Material NbCl
Mahtab A. Khan, Naseem Ud Din, Dmitry Skachkov +2
Flat electronic bands strongly enhance Coulomb interactions and can stabilize unconventional insulating states. Motivated by the recent discovery of flat bands in breathing Kagome…
Tuning the Electronic and Optical Properties of Impurity-Engineered Two-Dimensional Graphullerene Half-Semiconductors
M. A. Khan, Madeeha Atif, Michael N. Leuenberger
A novel material consisting of a monolayer of C buckyballs with hexagonal symmetry has recently been observed experimentally, named graphullerene. In this study, we present…
Dirac electrons in the presence of matrix potential barrier: application to graphene and topological insulators
Mikhail Erementchouk, Pinaki Mazumder, M. A. Khan +1
Scattering of a 2D Dirac electrons on a rectangular matrix potential barrier is considered using the formalism of spinor transfer matrices. It is shown, in particular, that in the…
Two-dimensional Fermionic Hong-Ou-Mandel Interference with Weyl Fermions
M. A. Khan, Michael N. Leuenberger
We propose a two-dimensional Hong-Ou-Mandel (HOM) type interference experiment for Weyl fermions in graphene and 3D topological insulators. Since Weyl fermions exhibit linear dispe…
