Unified Magnetoelectric Mechanism for Spin Splitting in Magnets
Carlos Mera Acosta
We identify a magnetoelectric correction that completes the theoretical description of spin splitting (SS) in magnetic systems. Derived from the Dirac equation, this term couples l…
Spin-deformation coupling in two-dimensional polar materials
J. A. Sánchez-Monroy, Carlos Mera Acosta
The control of the spin degree of freedom is at the heart of spintronics, which can potentially be achieved by spin-orbit coupling or band topological effects. In this paper, we ex…
Perspective on first-principles studies of 2D materials
Asha Yadav, Carlos Mera Acosta, Gustavo M. Dalpian +1
The successful exfoliation of graphene from graphite has brought significant attention to predicting new two-dimensional (2D) materials that can be realized experimentally. As a co…
Machine Learning Study of the Magnetic Ordering in 2D Materials
Carlos Mera Acosta, Elton Ogoshi, Jose Antonio Souza +1
Magnetic materials have been applied in a large variety of technologies, from data storage to quantum devices. The development of 2D materials has opened new arenas for magnetic co…
High throughput inverse design and Bayesian optimization of functionalities: spin splitting in two-dimensional compounds
Gabriel M. Nascimento, Elton Ogoshi, Adalberto Fazzio +2
The development of spintronic devices demands the existence of materials with some kind of spin splitting (SS). In this Data Descriptor, we build a database of ab initio calculated…
The different shapes of spin textures as a journey through Brillouin zone chiral and polar symmetries
Carlos Mera Acosta, Linding Yuan, Gustavo M. Dalpian +1
Crystallographic space group symmetry (CPGS) such as polar and nonpolar crystal classes have long been known to classify compounds that have spin-orbit-induced spin splitting. Whil…
Zeeman-type spin splitting in non-magnetic three-dimensional compounds: Materials prediction and electrical control
Carlos Mera Acosta, Adalberto Fazzio, Gustavo M. Dalpian
Despite its potential for device application, the non-magnetic Zeeman effect has only been predicted and observed in two-dimensional compounds. We demonstrate that non-centrosymmet…
Spin-polarization control driven by a Rashba-type effect breaking the mirror symmetry in two-dimensional dual topological insulators
Carlos Mera Acosta, Adalberto Fazzio
Three-dimensional topological insulators protected by both the time reversal (TR) and mirror symmetries were recently predicted and observed. Two-dimensional materials featuring th…
Analysis of Topological Transitions in Two-dimensional Materials by Compressed Sensing
Carlos Mera Acosta, Runhai Ouyang, Adalberto Fazzio +3
Quantum spin-Hall insulators (QSHIs), i.e., two-dimensional topological insulators (TIs) with a symmetry-protected band inversion, have attracted considerable scientific interest i…
A tight-binding model for the band dispersion in rhombohedral topological insulators over the whole Brilluoin zone
Carlos Mera Acosta, Matheus P. Lima, Antonio J. R. da Silva +2
We put forward a tight-binding model for rhombohedral topological insulators materials with the space group . The model describes the bulk band structure of…
Unconventional spin texture in a non-centrosymmetric quantum spin Hall insulator
Carlos Mera Acosta, O. Babilonia, L. B. Abdalla +1
We proposed that the simultaneous presence of both Rashba and band inversion can lead to a Rashba-like spin-splitting formed by two bands with the same in-plane helical spin textur…
Topological Phases in Triangular Lattices of Ru Adsorbed on Graphene: ab-initio calculations
C. Mera Acosta, Matheus P. Lima, R. H. Miwa +2
We have performed an ab initio investigation of the electronic properties of the graphene sheet adsorbed by Ru adatoms (Ru/graphene). For a particular set of triangular arrays of R…
