Beyond Disinformation: Strategic Misrepresentation across Content, Actors, Processes, and Covertness
Arttu Malkamäki, Daniel Balinhas, Letizia Iannucci +8
This article revisits the widely studied problem of disinformation and related phenomena in online social networks (OSNs) by reframing it as a broader problem of misrepresentation.…
Spin-Exchange Induced Spillover on Poor Man's Majoranas in Minimal Kitaev Chains
J. E. Sanches, L. T. Lustosa, L. S. Ricco +5
The "Poor Man's Majoranas" (PMMs) [Phys. Rev. B 86, 134528 (2012)] devoid of topological protection can "spill over" from one edge into another of the minimal Kitaev chain when per…
Optical properties of TiS as a novel thin film for single-junction and tandem solar cells
Cesar E. P. Villegas, Enesio Marinho, A. C. Dias +2
Sub-micrometer thin films are promising platforms for emerging flexible photovoltaic devices. Although the current market already produces efficient solar cells, the average wafer…
Impact of Broken Inversion Symmetry on Molecular States in multi-Weyl fermions
W. C. Silva, J. E. Sanches, D. S. Rojo +6
We study inversion-symmetry (IS) breaking in impurity dimers coupled to topological multi-Weyl systems in the low-energy dispersion domain. In the IS-preserved multi-Weyl semimetal…
Squeezed state protection of fine structure in "Poor Man's Majorana" via quantum spin coupling
J. E. Sanches, L. T. Lustosa, L. S. Ricco +5
The "Poor Man's Majorana" [Phys. Rev. B 86, 134528 (2012)] devoid of topological protection has been theoretically predicted to rely on the minimal Kitaev chain. Afterward, a pair…
Photovoltaic efficiency of transition metal dichalcogenides thin films by ab initio excited-state methods
Enesio Marinho, Cesar E. P. Villegas, Pedro Venezuela +1
Transition metal dichalcogenides (TMDCs) have garnered significant interest in optoelectronics, owing to their scalability and thickness-dependent electrical and optical properties…
Many-body effects on the quasiparticle band structure and optical response of single-layer penta-NiN
Enesio Marinho, Cesar E. P. Villegas, Pedro Venezuela +1
We present a comprehensive first-principles study on the optoelectronic properties of the single-layer nickel diazenide (penta-NiN), a recently synthesized Cairo pentagonal 2D…
Me-graphane: tailoring the structural and electronic properties of Me-graphene by hydrogenation
Enesio Marinho, Pedro A. S. Autreto
Graphene-based materials (GBMs) constitute a large family of materials which has attracted great interest for potential applications. In this work, we apply first-principles calcul…
Molybdenum Defect Complexes in Bismuth Vanadate
Enesio Marinho, Cedric Rocha Leão
Monoclinic bismuth vanadate (BiVO) is a promising -type semiconductor for applications in sunlight-driven water splitting. Several studies have shown that its photocatalytic…
Tuning Hydrogen Adsorption and Electronic Properties from Graphene to Fluorographone
Gabriel R. Schleder, Enesio Marinho, Douglas J. R. Baquiao +4
Graphene functionalization by hydrogen and fluorine has been proposed as a route to modulate its reactivity and electronic properties. However, until now, proposed systems present…
