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…
Double Resonant Tunable Second Harmonic Generation in Two-dimensional Layered Materials through Band Nesting
Sudipta Romen Biswas, Jin Yu, Zhenwei Wang +4
We proposed a mechanism to generate giant anisotropic second harmonic nonlinear response via double resonance effect, achieved through band nesting via electronic bandstructure eng…
Zitterbewegung of moiré excitons in twisted MoS/WSe hetero-bilayers
I. R. Lavor, D. R. da Costa, L. Covaci +3
The moiré pattern observed in stacked non-commensurate crystal lattices, such as hetero-bilayers of transition metal dichalcogenides, produces a periodic modulation of their bandga…
Isolated and hybrid bilayer graphene rings
M. Mirzakhani, D. R. da Costa, F. M. Peeters
Using the continuum model, we investigate the electronic properties of two types of bilayer graphene (BLG) quantum ring (QR) geometries: (i) an isolated BLG QR and (ii) a monolayer…
Signatures of sub-band excitons in few-layer black phosphorus
A. Chaves, G. O. Sousa, K. Khaliji +3
Recent experimental measurements of light absorption in few-layer black phosphorus (BP) reveal a series of high and sharp peaks, interspersed by pairs of lower and broader features…
