Endowing variational phase-field fracture models with custom strength criteria

This paper proposes a novel variational phase-field fracture framework that incorporates arbitrary elastic domains and custom strength criteria by introducing a state-dependent dissipation potential, thereby preserving the variational structure while allowing independent control over elastic degradation and crack nucleation under multiaxial stress states.

Low-loss Nb on Si superconducting resonators from a dual-use spintronics deposition chamber and with acid-free post-processing

This paper demonstrates that high-quality, low-loss niobium superconducting resonators can be fabricated in a dual-use chamber shared with magnetic materials by employing an acid-free resist strip process that achieves internal quality factors near one million, thereby enabling the integration of superconducting and magnetic systems without compromising device performance.

Temperature dependence of the spontaneous magnetization of Ni2MnGa and other ferromagnets. The superellipse equation

This paper proposes that the temperature dependence of spontaneous magnetization in ferromagnets like Ni2MnGa can be fully described across the entire temperature range by a superellipse equation using only the Curie temperature and a single dimensionless critical exponent, allowing the behavior near the critical point to be predicted from low-temperature measurements through the symmetric interchange of reduced variables.

Krypton-sputtered tantalum films for scalable high-performance quantum devices

This paper demonstrates that using krypton instead of argon as a sputter gas enables the scalable, low-temperature synthesis of high-purity, body-centered cubic tantalum films with superior electronic conductivity, resulting in state-of-the-art superconducting resonators and transmon qubits with quality factors up to 14 million.

From Symmetry to Stability: Structural and Electronic Transformation in Cs2_2KInI6_6

This study employs a synergistic approach combining genetic algorithms, machine-learned potentials, and first-principles calculations to reveal that the lead-free double perovskite Cs2_2KInI6_6 lacks a stable cubic phase, instead identifying lower-symmetry structures that trade structural stability for widened, indirect band gaps.
