Anomalous magneto-optical response at van der Waals interface
Muhammad Hassan Shaikh, Abhijith Puthiya Veettil, Collin Maurtua +9
Ruthenium dioxide () has been proposed as an altermagnetic candidate, although its magnetic ground state remains controversial. Here, we probe weak interfacial magn…
Strong electron correlations and ligand hybridization for altermagnetism
Byungkyun Kang, Anderson Janotti, Dai Q. Ho +5
Spin-band splitting is a hallmark of altermagnetism, intrinsically linked to magnetic ordering driven by electron correlations. However, recent inconsistencies in the detection of…
Deterministic Realization of Complex Local Strain Fields and Bandgap Profiles in Two-Dimensional Materials
Lottie L. Murray, Eric Herrmann, Igor Evangelista +5
Emerging classical and quantum device concepts demand precise spatial control over the optoelectronic properties of two-dimensional (2D) materials, but deterministic engineering vi…
Resonance-enhanced super-superexchange yields giant chiral magnon splitting in rutile altermagnets
Dai Q. Ho, D. Quang To, Byungkyun Kang +3
Altermagnets host momentum-selective spin splitting and chiral-split magnonic excitations despite vanishing net magnetization, enabling spin transport without ferromagnetism. In ru…
Sequential Quenching to Predict Semiconductor Defect Concentrations from Formation & Migration Energies: The Case of CdTe:As Doping
Khandakar Aaditta Arnab, Intuon Chatratin, Anderson Janotti +1
Defect concentrations in semiconductors are strongly influenced by thermal history during growth and cooldown, yet most defect calculations assume either instantaneous quenching fr…
Effects of uniaxial strain on monolayer transition-metal dichalcogenides revisited
Igor Evangelista, Abdul Saboor, Muhammad Zubair +6
Using hybrid density functional calculations including spin-orbit coupling, we compute the strain evolution of the band structure of monolayer 1H-phase transition-metal dichalcogen…
