Ferroelectric Altermagnetic Chern Insulator in magnetic field: electrical control of the Chern number
Meysam Bagheri Tagani, Carmine Autieri
We investigate electrically controllable Chern topology in a two-dimensional compensated (d)-wave altermagnet described by a lattice-regularized Bernevig--Hughes--Zhang model. In t…
Berry-Curvature Activation by Orbital Flux in a Kagome Altermagnet
Meysam Bagheri Tagani, Carmine Autieri
We investigate topological electronic responses in a kagome altermagnetic metal hosting a compensated coplanar magnetic texture. Using a minimal tight-binding model con…
Machine Learning and Deep Learning in Quantum Materials: Symmetry, Topology, and the Rise of Altermagnets
Mahyar Hassani-Vasmejani, Hosein Alavi-Rad, Meysam Bagheri Tagani
The landscape of condensed matter physics is facing an unprecedented data surge driven by high-throughput ab initio workflows and rapidly expanding experimental datasets. Tradition…
Long-Lived Interlayer Excitons and Type-II Band Alignment in Janus MoTe2/CrSBr van der Waals Heterostructures
Mohammad Ali Mohebpour, Peter C Sherrell, Catherine Stampfl +2
Identifying two-dimensional heterostructures with exceptional electronic and optical properties remains an active area of research in advanced optoelectronics. Here, we present a c…
Kagome goldene with flat bands and Dirac nodal line fermions via line-graph epitaxy
Qiwei Tian, Sahar Izadi Vishkayi, Chen Zhang +8
The kagome lattice has emerged as a promising platform for investigating exotic quantum phases. However, achieving a single-atomic-layer kagome lattice in elemental materials remai…
First-Principles Insights into Excitonic and Electron-Phonon Effects in van der Waals Heterostructures
Mohammad Ali Mohebpour, Carmine Autieri, Meysam Bagheri Tagani
Motivated by the successful synthesis of isolated ZrS2 and HfS2 transition metal dichalcogenide (TMD) monolayers and inspired by their nearly identical lattice constants, we constr…
