Unambiguous Simulation of Diffusive Charge Transport in Disordered Nanoribbons
H. P. Veiga, S. M. João, J. M. Alendouro Pinho +2
Charge transport in disordered two-dimensional (2D) systems showcases a myriad of unique phenomenologies that highlight different aspects of the underlying quantum dynamics. Electr…
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…
