Tuning of exciton type by environmental screening
Igor L. C. Lima, M. V. Milošević, F. M. Peeters +1
We theoretically investigate the binding energy and electron-hole (e-h) overlap of excitonic states confined at the interface between two-dimensional materials with type-II band al…
A Gross-Pitaevskii theory for an excitonic incompressible Bose solid
Sara Conti, Andrey Chaves, Alexander R. Hamilton +3
We show that interlayer excitons in double-layer semiconductor heterostructures can form a Bose solid, which is an incompressible supersolid characterized by exactly one boson per…
Striped excitonic (super)solid in anisotropic semiconductors with screened exciton interactions
J. F. de Oliveira Neto, F. M. A. Guimarães, Davi S. Dantas +3
Within the Gross-Pitaevskii framework, we reveal the emergence of a crystallized phase of an exciton condensate in an atomically-thin anisotropic semiconductor, where screening of…
Wave-packet dynamics in a graphene with periodic potentials
M. M. Suleimanov, M. U. Nosirov, H. T. Yusupov +3
We use the Dirac continuum model to study the propagation of electronic wave packets in graphene with periodically arranged circular potential steps. The time propagation of the wa…
Energy levels and Aharonov-Bohm oscillations in twisted bilayer graphene quantum dots and rings
N. S. Bandeira, Andrey Chaves, L. V. de Castro +4
We present a systematic study of the energy levels of twisted bilayer graphene (tBLG) quantum dots (QD) and rings (QR) under an external perpendicular magnetic field. The confineme…
Chiral propagation of plasmons due to competing anisotropies in a twisted photonic heterostructure
Ze-Hua Tao, Icaro R. Lavor, Hai-Ming Dong +3
We demonstrate chiral propagation of plasmon polaritons and show it is more efficient and easier to control than the recently observed chiral shear phonon polaritons. We consider p…
Ultrasensitive acoustic graphene plasmons in a graphene-transition metal dichalcogenide heterostructure: strong plasmon-phonon coupling and wavelength sensitivity enhanced by a metal screen
Ícaro R. Lavora, Z. H. Tao, H. M. Dongd +3
Acoustic plasmons in graphene exhibit strong confinement induced by a proximate metal surface and hybridize with phonons of transition metal dichalcogenides (TMDs) when these mater…
Wave-packet scattering at a normal-superconductor interface in two-dimensional materials: a generalized theoretical approach
F. J. A. Linard, V. N. Moura, L. Covaci +2
A wave-packet time evolution method, based on the split-operator technique, is developed to investigate the scattering of quasi-particles at a normal-superconductor interface of ar…
