Robust NbN‐on‐Si/SiGe Hybrid Microwave Quantum Circuits With Long‐Term Stability

Advanced Electronic Materials, EarlyView.
Superconducting NbN resonators integrated with Si/SiGe quantum wells based semiconducting chip are investigated as a CMOS–compatible platform for scalable quantum hardware. Temperature–dependent microwave spectroscopy reveals loss mechanisms from TLS, quasiparticles, and scattering.

Dual-phase superconductivity in high-pressure high-temperature synthesized TaNbZrHfTi

AIP Advances
We report on a novel TaNbZrHfTi-based high entropy alloy (HEA) which demonstrates distinctive dual-phase superconductivity. The HEA was synthesized under high pressures and high temperatures starting from a ball milled mixture of elemental metals in a ...

Extrinsic and Intrinsic Charge Transfer at Interfaces of Membrane‐Based Oxide Heterostructures

Advanced Electronic Materials, EarlyView.
Freestanding oxides have emerged as a new opportunity to tailor oxides outside of the typical epitaxial constraints. We present the fabrication of TiO2‐terminated SrTiO3 membranes via direct growth control. We demonstrate competing ionic and electronic charge transfer in LaAlO3/SrTiO3 bilayers using near ambient pressure XPS.

Aspects of Holographic Superconductivity [PDF]

, 2012
In this thesis we study two different aspects of holographic superconductivity. First we study fully backreacting Gauss-Bonnet (GB) holographic superconductors in 5 bulk spacetime dimensions. We explore the system’s dependence on the scalar mass for both

Materials Representation Learning Based on a Material–Motif Network and Heterogeneous Graphs

Advanced Intelligent Discovery, EarlyView.
Structure motifs in materials are used to construct a bipartite material–motif network that links each material to its constituent motifs and establishes connectivity among materials sharing common motifs. Network analysis reveals material clusters associated with different functional applications and supports motif‐guided screening of materials.

Unconventional density-wave state in Ruddlesden‒Popper nickelate La4Ni3O10

Nature Communications
The recent discovery of superconductivity in Ruddlesden‒Popper (RP) nickelates Rn+1NinO3n+1 (R = rare earth) under high pressure provides a new platform to understand the underlying physics of high-temperature superconductivity.

From Data to Discovery: Machine Learning–Enabled Intelligent Characterization of Two‐Dimensional Materials

Advanced Intelligent Discovery, EarlyView.
Machine learning serves as a central engine for the intelligent characterization of two‐dimensional materials by integrating multimodal techniques, including optical microscopy, spectroscopy, electron microscopy, and scanning probe microscopy (SPM). This unified framework enables automated, high‐throughput, and quantitative extraction of structural ...
