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…
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…
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…
