Interacting Virtual Topological Phases in Defect-Rich 2D Materials
Felipe Crasto de Lima, Roberto H. Miwa, Caio Lewenkopf +1
We investigate the robustness of {\it virtual} topological states -- topological phases away from the Fermi energy -- against the electron-electron interaction and band filling. As…
Oscillatory properties of strange quark stars described by the vector MIT bag model
Luiz L. Lopes, Jose C. Jimenez, Luis B. Castro +1
We investigated the radial and non-radial fundamental () mode oscillations of self-bound (quark) stars obtained after employing the Vector MIT (vMIT) bag model. Within this mode…
Shaping terahertz waves using anisotropic shear modes in a van der Waals mineral
Nicolas M. Kawahala, Daniel A. Matos, Raphaela de Oliveira +4
Naturally occurring van der Waals (vdW) materials are currently attracting significant interest due to their potential as low-cost sources of two-dimensional materials. Valuable in…
Reentrant topological phase in half-Heusler compounds
Augusto L. Araújo, Felipe Crasto de Lima, Adalberto Fazzio
Half-Heusler compounds are known for their various compositions and multifunctional properties including topological phases. In this study, we investigate the topological classific…
Measurement of exclusive and production at TeV
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1075
Measurements are presented of the cross-section for the central exclusive production of and processes in proton-proton collisions at $\sqrt{s} = 13…
How the QCD trace anomaly behaves at the core of twin stars?
José C. Jiménez, Lucas Lazzari, Victor P. Gonçalves
We investigate the behavior of the dense and cold (normalized) QCD trace anomaly, , in the interior of twin neutron stars (obtained from several sets of equations of state in ag…
Unraveling the Spin-to-Charge Current Conversion Mechanism and Charge Transfer Dynamics at Interface of Graphene/WS Heterostructures at Room Temperature
Rafael O. Cunha, Yunier Garcia-Basabe, Dunieskys G. Larrude +7
We report experimental investigations of spin-to-charge current conversion and charge transfer dynamics (CT) at the interface of graphene/WS van der Waals heterostructure. Pure…
Exploring Topological Transport in PtHgSe Nanoribbons: Insights for Spintronic Device Integration
Rafael L. H. Freire, F. Crasto de Lima, Roberto H. Miwa +1
The discovery of the quantum spin Hall effect led to the exploration of the electronic transport for spintronic devices. Here, we theoretically investigated the electronic conducta…
Importance of the semimetallic state for the quantum Hall effect in HfTe
M. M. Piva, R. Wawrzyńczak, Nitesh Kumar +5
At ambient pressure, HfTe is a material at the boundary between a weak and a strong topological phase, which can be tuned by changes in its crystalline structure or by the ap…
