Broken-symmetry magnetic phases in two-dimensional triangulene crystals
G. Catarina, J. C. G. Henriques, A. Molina-Sánchez +2
We provide a comprehensive theory of magnetic phases in two-dimensional triangulene crystals, using both Hubbard model and density functional theory (DFT) calculations. We consider…
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…
Quantum dynamics for energetic advantage in a charge-based classical full-adder
João P. Moutinho, Marco Pezzutto, Sagar Pratapsi +5
We present a proposal for a one-bit full-adder to process classical information based on the quantum reversible dynamics of a triple quantum dot system. The device works via the re…
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…
Ising and XY paramagnons in two-dimensional 2H-NbSe
A. T. Costa, M. Costa, J. Fernández-Rossier
Paramagnons are the collective modes that govern the spin response of nearly magnetic conductors. In some cases they mediate electron pairing leading to superconductivity. This sce…
Enhancing the hybridization of plasmons in graphene with 2D superconductor collective modes
A. T. Costa, N. M. R. Peres
We explore ways in which the close proximity between graphene sheets and monolayers of 2D superconductors can lead to hybridization between their collective excitations. We conside…
