Valley-selective confinement of excitons in transition metal dichalcogenides with inhomogeneous magnetic fields
A. J. Chaves, D. R. da Costa, F. M. Peeters +1
Magnetized ferromagnetic disks or wires support strong inhomogeneous fields in their borders. Such magnetic fields create an effective potential, due to Zeeman and diamagnetic cont…
Moiré excitons in biased twisted bilayer graphene under pressure
V. G. M. Duarte, D. R. da Costa, N. M. R. Peres +2
Using the tight-binding model, we report a gap opening in the energy spectrum of the twisted bilayer graphene under the application of pressure, that can be further amplified by th…
Trion clustering structure and binding energy in 2D semiconductor materials: Faddeev equations approach
K. Mohseni, M. R. Hadizadeh, T. Frederico +2
In this work, we develop the basic formalism to study trions in semiconductor layered materials using the Faddeev equations in momentum space for three different particles lying in…
Three-boson stability for boosted interactions towards the zero-range limit
K. Mohseni, A. J. Chaves, D. R. da Costa +2
We study the three-boson bound-state mass and wave functions for ground and excited states within the three-body relativistic framework with Kamada and Glöcke boosted potentials in…
Stark shift of excitons and trions in two-dimensional materials
L. S. R. Cavalcante, D. R. da Costa, G. A. Farias +2
The effect of an external in-plane electric field on neutral and charged exciton states in two-dimensional (2D) materials is theoretically investigated. These states are argued to…
Localized surface plasmons in a continuous and flat graphene sheet
André J. Chaves, Diego R. Costa, Gil A. Farias +1
We derive an integral equation describing surface-plasmon polaritons in graphene deposited on a substrate with a planar surface and a dielectric protrusion in the opposite surface…
Interfacial confinement in core-shell nanowires due to high dielectric mismatch
A. A. Sousa, T. A. S. Pereira, A. Chaves +2
We theoretically investigate the role of the dielectric mismatch between materials on the energy levels and recombination energies of a core-shell nanowire. Our results demonstrate…
