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…
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…
A New Microscopic Look into Pressure Fields and Local Buoyancy
Simão M. João, J. P. Santos Pires, J. M. Viana Parente Lopes
The concept of local pressure is pivotal to describe many important physical phenomena, such as buoyancy or atmospheric phenomena, which always require the consideration of space-v…
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…
Basis-Independent Spectral Methods for Non-linear Optical Response in Arbitrary Tight-binding Models
S. M. João, J. M. V. P. Lopes
In this paper, we developed a basis-independent perturbative method for calculating the non-linear optical response of arbitrary non-interacting tight-binding models. Our method is…
