Charge fluctuations and topological phases in Kitaev-Heisenberg ladders
M. G. Sousa, O. Ávalos-Ovando, E. Vernek +1
We investigate the stability of topological phases in doped Kitaev-Heisenberg ladders by studying the competition with itinerant electrons and the associated charge fluctuations in…
Reversible edge spin currents in antiferromagnetically proximitized dichalcogenides
Natalia Cortés, O. Ávalos-Ovando, S. E. Ulloa
We explore proximity effects on transition metal dichalcogenide ribbons deposited on antiferromagnetic (AFM) insulating substrates. We model these hybrid heterostructures using a t…
Competing long-range interactions and spin vector chirality in spin-chains
E. Vernek, O. Ávalos-Ovando, S. E. Ulloa
Studies of competing orders in 1D magnetic chains have attracted considerable attention in recent years, as the presence of long-range Heisenberg interactions is found to allow int…
Lateral heterostructures and one-dimensional interfaces in 2D transition metal dichalcogenides
Oscar Ávalos-Ovando, Diego Mastrogiuseppe, Sergio E. Ulloa
The growth and exfoliation of two-dimensional (2D) materials have led to the creation of edges and novel interfacial states at the juncture between crystals with different composit…
Lateral Interfaces of Transition Metal Dichalcogenides: A Stable Tunable One-Dimensional Physics Platform
Oscar Ávalos-Ovando, Diego Mastrogiuseppe, Sergio E. Ulloa
We study in-plane lateral heterostructures of commensurate transition-metal dichalcogenides, such as MoS-WS and MoSe-WSe, and find interfacial and edge stat…
Tunable spin-polarized edge currents in proximitized transition metal dichalcogenides
Natalia Cortés, O. Ávalos-Ovando, L. Rosales +2
We explore proximity-induced ferromagnetism on transition metal dichalcogenide (TMD), focusing on molybdenum ditelluride (MoTe) ribbons with zigzag edges, deposited on ferrom…
Symmetries and hybridization in the indirect interaction between magnetic moments in MoS nanoflakes
Oscar Ávalos-Ovando, Diego Mastrogiuseppe, Sergio E. Ulloa
We study the Ruderman-Kittel-Kasuya-Yosida interaction between magnetic impurities embedded in -doped transition metal dichalcogenide triangular flakes. The role of underlying s…
Long range of indirect exchange interaction on the edges of MoS flakes
Oscar Ávalos-Ovando, Diego Mastrogiuseppe, Sergio E. Ulloa
We study the Ruderman-Kittel-Kasuya-Yosida interaction between two magnetic impurities connected to the edges of zigzag-terminated MoS flakes. When the impurities lie on the…
Noncollinear exchange interaction in transition metal dichalcogenide edges
Oscar Ávalos-Ovando, Diego Mastrogiuseppe, Sergio E. Ulloa
We study the Ruderman-Kittel-Kasuya-Yosida effective exchange interaction between magnetic impurities embedded on the edges of transition-metal dichalcogenide flakes, using a three…
