Symmetry Engineering Enables Deterministic Ensemble Polarization Control in Hexagonal Boron Nitride
Aqiq Ishraq, Eric Herrmann, Pragya Agnihotri +15
Optical polarization is a key degree of freedom in quantum photonic and sensing technologies, enabling efficient light--matter coupling and directional emission. However, in defect…
Small-supercell and Small-dataset Training Strategy of Machine Learning Interatomic Potentials for Point Defects
Zhenxing Dai, Mingjue Ni, Xinpeng Li +3
Machine learning interatomic potentials (MLIPs) can treat large-scale material systems with near first-principles accuracy and have been widely used to accelerate point-defect simu…
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…
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…
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…
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…
Quantifying the Relationship Between Strain and Bandgap in Thin GaSe
Lottie L. Murray, Eric Herrmann, Igor Evangelista +3
We present a rigorous analysis that combines theory, simulation, and experimental measurements to quantify the relationship between strain and bandgap in two dimensional gallium se…
Quantum geometric origins of the orbital degrees of freedom of hybrid bosonic quasiparticles in magnetic systems
D. Quang To, Dai Q. Ho, Joshua M. O. Zide +5
The orbital degree of freedom has recently attracted significant attention due to the novel phenomena it enables in condensed matter systems. However, the interpretation of the orb…
Probing Magnetic Properties of RuO Heterostructures Through the Ferromagnetic Layer
Frank M. Abel, Subhash Bhatt, Shelby S. Fields +20
RuO has been proposed as the prototypical altermagnetic material. However, several reports have recently questioned its intrinsic magnetic ordering, leading to conflicting fi…
Tunable magnon band topology and magnon orbital Nernst effect in noncollinear antiferromagnets
