Characterization of ultrathin nickel films deposited by thermal laser evaporation

Kavli Affiliate: Austin Minnich | Summary:Thermal laser evaporation is a physical vapor deposition technique of increasing interest because of its ability to evaporate essentially any solid element, even the most refractory such as W. However, many films deposited by this method, especially non-epitaxial films, remain to be characterized; further, key system components such as the […]

Beyond Accuracy: Measuring Bias Acknowledgment in Chain-of-Thought Reasoning for Responsible AI Evaluation

Kavli Affiliate: Wei Gao| Summary:Reasoning models are increasingly used in settings where the final answer is not the only object of review: educational tools may show students intermediate steps, decision-support systems may require human oversight, and audit workflows may inspect traces for misleading or biased input. In such settings, two responses can receive the same […]

Data-driven surrogate models for forecasting experimentally measured fluid flows

Kavli Affiliate: Morteza Gharib| Summary:Data-driven modeling shows significant promise for faster-than-real-time forecasting of fluid flows. For real-world engineering applications (e.g., flow control), models must contend with limited, imperfect, and incomplete experimental measurements. In this work, we present an analysis of data-driven surrogate models trained to forecast the time-evolution of experimentally measured cylinder wakes in the […]

Dominant in-plane anomalous Hall effect in a monoclinic room-temperature ferromagnet

Kavli Affiliate: Linda Ye| Summary:Ferromagnetic metals are characterized by enhanced dissipationless transverse transport responses via the anomalous Hall effect, offering a route towards magnetic sensing and spintronic readout functionalities. In most ferromagnets, the anomalous Hall current is constrained to lie in the plane perpendicular to the magnetization (or applied magnetic field). Recently, it has been […]

Quantum Hall effect in vacancy-engineered $β$-Ag$_2$Te

Kavli Affiliate: Joseph Falson | Summary:Accessing surface quantum transport in topological insulators is hampered by residual bulk conduction arising from lattice defects. Here, we demonstrate a novel synthesis pathway for realizing high mobility $β$-Ag$_2$Te thin films where surface transport is dominant. An textitin-situ vacancy engineering step as part of the molecular beam epitaxy growth process […]

Bionic Human-Motion Style Transfer for Physically Executable Whole-Body Control of Humanoid Robots

Kavli Affiliate: Wei Gao| Summary:Expressive whole-body motion is important for humanoid robots operating in human environments, where robots are expected to move stably while presenting readable and adjustable body behaviors. However, most expressive motions are still obtained from fixed demonstrations or manually designed scripts, making it difficult to reuse a demonstrated style across different motion […]
