Anisotropic magnon transport in an antiferromagnetic trilayer heterostructure: is BiFeO$_3$ an altermagnet?

Kavli Affiliate: James Analytis| Summary:Magnons provide a route to ultra-fast transport and non-destructive readout of spin-based information transfer. Here, we report magnon transport and its emergent anisotropic nature in BiFeO$_3$ layers confined between ultrathin layers of the antiferromagnet LaFeO$_3$. Due to the confined state, BiFeO$_3$ serves as an efficient magnon transmission channel as well as […]

Solvent Effects on Triplet Yields in BODIPY-Based Photosensitizers

Kavli Affiliate: David T. Limmer | Summary:We employ molecular dynamics simulations and quantum rate theories to elucidate the complex condensed-phase dynamics underpinning triplet-state formation in organic photosensitizers. Using models informed by first-principles calculations complete with a molecular representation of solvents of different polarities, we elucidate the interplay of the internal and environmental interactions underlying triplet […]

Nanocrystal Geometry Governs Phase Transformation Pathways in Palladium Hydride

Kavli Affiliate: David T. Limmer | Summary:Pathways and structural dynamics of phase transformations impact performance of materials in energy and information storage technologies. Palladium hydride ($mathrmPdH_x$) nanocrystals are an ideal model system for studying solute-induced phase transformations, where elastic energy from lattice mismatch between $α$-$mathrmPdH_x$ and $β$-$mathrmPdH_x$ phases is often considered a key to determining […]

Easier randomizing gates provide more accurate fidelity estimation

Kavli Affiliate: Irfan Siddiqi | Summary:Accurate benchmarking of quantum gates is crucial for understanding and enhancing the performance of quantum hardware. A standard method for this is interleaved benchmarking, a technique which estimates the error on an interleaved target gate by comparing cumulative error rates of randomized sequences implemented with the interleaved gate and without […]

CASCADE: Cumulative Agentic Skill Creation through Autonomous Development and Evolution

Kavli Affiliate: Gerbrand Ceder| Summary:Large language model (LLM) agents currently depend on predefined tools or early-stage tool generation, limiting their adaptability and scalability to complex scientific tasks. We introduce CASCADE, a self-evolving agentic framework representing an early instantiation of the transition from "LLM + tool use" to "LLM + skill acquisition". CASCADE enables agents to […]

Imaging Electron-Hole Asymmetry in the Quantum Melting of Generalized Wigner Crystals

Kavli Affiliate: Michael Crommie | Summary:Two-dimensional moiré materials provide a versatile platform to explore phase transitions in strongly correlated systems. Using scanning tunneling microscopy (STM) we have imaged the density-driven melting of generalized Wigner crystals (GWCs) and Mott insulators (MIs) in electron-doped, near-60° twisted MoSe2 bilayers featuring a triangular moiré superlattice. We observe striking electron-hole […]

Spin Polarization from Circularly Polarized Light Induced Charge Transfer

Kavli Affiliate: David T. Limmer | Summary:We show how a spin polarization can be generated through the photo-induced electron transfer of an achiral donor-acceptor complex following chiral light excitation. In particular, we illustrate the basic energetic and symmetry requirements for chirality induced spin selectivity where the chirality emerges from the electronic degrees of freedom following […]
