Magneto-optical Kerr effect in spin split two-dimensional massive Dirac materials
G. Catarina, N. M. R. Peres, J. Fernández-Rossier
Two-dimensional (2D) massive Dirac electrons possess a finite Berry curvature, with Chern number , that entails both a quantized dc Hall response and a subgap full-quarter…
Probing Band-center Anomaly with the Kernel Polynomial Method
N. A. Khan, Syed Tahir Amin
We investigate the anomalous behavior of localization length of a non-interacting one-dimensional Anderson model at zero temperature. We report numerical calculations of the Thoule…
KITE: high-performance accurate modelling of electronic structure and response functions of large molecules, disordered crystals and heterostructures
Simão M. João, Miša Anđelković, Lucian Covaci +3
We present KITE, a general purpose open-source tight-binding software for accurate real-space simulations of electronic structure and quantum transport properties of large-scale mo…
The magnetic Purcell effect: the case of an emitter near an antiferromagnet
Beatriz A. Ferreira, N. M. R. Peres
In this paper we discuss the magnetic Purcell effect of a magnetic dipole near a semi-infinite antiferromagnet. Contrary to the electric Purcell effect, the magnetic one is not so…
Near-unity light absorption in a monolayer WS2 van der Waals heterostructure cavity
Itai Epstein, Bernat Terrés, André J. Chaves +12
Excitons in monolayer transition-metal-dichalcogenides (TMDs) dominate their optical response and exhibit strong light-matter interactions with lifetime-limited emission. While var…
Landauer transport as a quasisteady state on finite chains under unitary quantum dynamics
J. P. Santos Pires, B. Amorim, J. M. Viana Parente Lopes
In this paper, we study the emergence of a Landauer transport regime from the quantum-mechanical dynamics of free electrons in a disordered tight-binding chain, which is coupled to…
Disorder driven multifractality transition in Weyl nodal loops
Miguel Gonçalves, Pedro Ribeiro, Eduardo V. Castro +1
The effect of short-range disorder in nodal line semimetals is studied by numerically exact means. For arbitrary small disorder, a novel semimetallic phase is unveiled for which th…
Twisted bilayer graphene: low-energy physics, electronic and optical properties
G. Catarina, B. Amorim, Eduardo V. Castro +2
Van der Waals (vdW) heterostructures ---formed by stacking or growing two-dimensional (2D) crystals on top of each other--- have emerged as a new promising route to tailor and engi…
Robust band of critical states in T broken fermionic systems with lattice selective disorder
Eduardo V. Castro, Raphael de Gail, M. Pilar López-Sancho +1
We analyze the localization properties of two dimensional systems based on partite lattices with a basis. Contrary to standard results, we find that a band of critical states emerg…
Global Delocalization Transition in the de Moura-Lyra Model
J. P. Santos Pires, N. A. Khan, J. M. Viana Parente Lopes +1
The possibility of having a delocalization transition in the 1D de Moura-Lyra class of models (having a power-spectrum has been the object of a long standing disc…
A study of the nonlinear optical response of the plain graphene and gapped graphene monolayers beyond the Dirac approximation
G. B. Ventura, D. J. Passos, J. M. Viana Parente Lopes +1
In this work, we present numerical results for the second and third order conductivities of the plain graphene and gapped graphene monolayers associated with the second and third h…
