From Bloch Oscillations to a Steady-State Current in Strongly Biased Mesoscopic Devices
J. M. Alendouro Pinho, J. P. Santos Pires, Simão M. João +2
It has long been known that quantum particles moving in a periodic lattice and subject to a constant force field undergo an oscillatory motion that is referred to as Bloch Oscillat…
Anomalous Transport Signatures in Weyl Semimetals with Point Defects
J. P. Santos Pires, Simão M. João, Aires Ferreira +2
We present the first theoretical study of transport properties of Weyl semimetals with point defects. Focusing on a class of time-reversal symmetric Weyl lattice models, we show th…
Nodal vacancy bound states and resonances in three-dimensional Weyl semimetals
J. P. Santos Pires, S. M. João, Aires Ferreira +2
The electronic structure of a cubic -symmetric Weyl semimetal is analysed in the presence of atomic-sized vacancy defects. Isolated vacancies are shown to generate nod…
Two limit cases of twisted hBN bilayers and their excitonic response
J. C. G. Henriques, B. Amorim, R. M. Ribeiro +1
In this paper we discuss the optical response due to the excitonic effect of two types of hBN bilayers: AB and AA'. Understanding the properties of these bilayers is of great utili…
Breakdown of universality in three-dimensional Dirac semimetals with random impurities
J. P. Santos Pires, B. Amorim, Aires Ferreira +3
Dirac-Weyl semimetals are unique three-dimensional (3D) phases of matter with gapless electrons and novel electrodynamic properties believed to be robust against weak perturbations…
Exciton-polariton mediated interaction between two nitrogen-vacancy color centers in diamond using two-dimensional transition metal dichalcogenides
J. C. G. Henriques, B. Amorim, N. M. R. Peres
In this paper, starting from a quantum master equation, we discuss the interaction between two negatively charged Nitrogen-vacancy color centers in diamond via exciton-polaritons p…
