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…
