Optical Properties of Gated Bilayer Graphene Quantum Dots with Trigonal Warping
Matthew Albert, Daniel Miravet, Yasser Saleem +4
We determine the optical properties of gated bilayer graphene quantum dots with trigonal warping (TW) of single-particle energy spectra. The lateral structure of metallic gates con…
Superexchange Mechanism in Coupled Triangulenes Forming Spin-1 Chains
Yasser Saleem, Torben Steenbock, Emha Riyadhul Jinan Alhadi +3
We show that the origin of the antiferromagnetic coupling in spin-1 triangulene chains, which were recently synthesized and measured by Mishra et al. Nature 598, 287-292 (2021) ori…
Electrically Tunable Fine Structure of Negatively Charged Excitons in Gated Bilayer Graphene Quantum Dots
Katarzyna Sadecka, Yasser Saleem, Daniel Miravet +4
We predict here the fine structure of an electrically tunable negatively charged exciton (trion) composed of two electrons and a hole confined in a gated bilayer graphene quantum d…
Quantum simulator of extended bipartite Hubbard model with broken sublattice symmetry: magnetism, correlations, and phase transitions
Yasser Saleem, Amintor Dusko, Moritz Cygorek +2
We describe here a quantum simulator of extended bipartite Hubbard model with broken sublattice symmetry. The simulator consists of a structured lateral gate confining two dimensio…
