Frustrated Topological Orbital Magnetism

This paper proposes a new class of phenomena termed "frustrated topological orbital magnetism," where the interplay of geometric frustration and Aharonov-Bohm fluxes in three-dimensional systems generates topological semimetallic ground states with complex orbital magnetic orders (dipole, quadrupole, and ferrotoroidic) that induce measurable current-induced Hall effects and anisotropic responses linked to specific nodal line and Weyl node topologies.

Demonstration of on-chip all-optical switching of magnetization in integrated photonics

This paper demonstrates the first deterministic, single-pulse all-optical magnetization switching within a silicon nitride photonic integrated circuit, achieving high-contrast toggle switching in sub-micron Co/Gd devices and highlighting the critical role of device scaling for robust, fully integrated spintronic-photonic platforms.

Robust Excitonic Coherence Driven by In-Plane Anisotropy in a van der Waals Semiconductor

Using transient micro-four-wave mixing spectroscopy, researchers demonstrate that in-plane anisotropy in pristine layered rhenium disulfide (ReS2) drives robust excitonic coherence with resilience against density and temperature variations, enabling measurable quantum features at room temperature due to homogeneous transitions and low disorder.

Dynamical many-body control of high harmonic generation in a Mott insulator

This study demonstrates that high harmonic generation in the Mott insulator La2_2CuO4_4 serves as a sensitive probe of correlation-driven electronic dynamics, revealing a robust 4 eV cutoff defined by Hubbard bands and showing how photo-doping triggers many-body band reconstruction that suppresses nonlinear intraband currents.

Symmetric Mode Ansatz: Theory of Magnon Collective Modes in Chern Insulators

This paper introduces the Symmetric Mode Ansatz (SyMA), a generalized single-mode approximation that accurately describes the low-energy magnon spectrum and gap in Chern insulators, including fractional states, by proving its exactness in specific solvable Hubbard models and demonstrating that uniform quantum geometry is sufficient to stabilize magnetism.
