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…
Strongly coupled magnon-plasmon polaritons in graphene- 2D ferromagnet heterostructures
A. T. Costa, M. I. Vasilevskiy, J. Fernández-Rossier +1
Magnons and plasmons are two very different types of collective modes, acting on the spin and charge degrees of freedom, respectively. At first sight, the formation of hybrid plasm…
Theory of triangulene two-dimensional crystals
R. Ortiz, G. Catarina, J. Fernández-Rossier
Equilateral triangle-shaped graphene nanoislands with a lateral dimension of benzene rings are known as triangulenes. Individual triangulenes are open-shell molecules…
Excitonic instability in transition metal dichalcogenides
M. F. C. Martins Quintela, A. T. Costa, N. M. R. Peres
When transition-metal dichalcogenide monolayers lack inversion symmetry, their low-energy single particle spectrum can described by tilted massive Dirac Hamiltonians. The so-called…
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…
Tunable Excitons in Rhombohedral Trilayer Graphene
M. F. C. Martins Quintela, N. M. R. Peres
Trilayer graphene is receiving an increasing level of attention due to its stacking--dependent magnetoelectric and optoelectric properties, and its more robust ferromagnetism relat…
