Flux trapping in NbTiN strips and structures

Kavli Affiliate: Katja C. Nowack | First 5 Authors: Ruiheng Bai, Aliakbar Sepehri, Yen-Lee Loh, Anne-Marie Valente-Feliciano, Anna Herr | Summary: We use scanning superconducting quantum interference device (SQUID) microscopy to image vortices in superconducting strips fabricated from NbTiN thin films. We repeatedly cool superconducting strips with different width in an applied magnetic field and […]

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

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Maciej W. Olszewski, Jadrien T. Paustian, Tathagata Banerjee, Haoran Lu, Jorge L. Ramirez | Summary: Magnetic impurities are known to degrade superconductivity. For this reason, physical vapor deposition chambers that have previously been used for magnetic materials have generally been avoided for making high-quality superconducting resonator […]

Microscopic mechanisms of flexoelectricity in oxide membranes

Kavli Affiliate: David A. Muller | First 5 Authors: Harikrishnan KP, Varun Harbola, Jaehong Choi, Kevin J. Crust, Yu-Tsun Shao | Summary: Modern electromechanical actuators and sensors rely on the piezoelectric effect that linearly couples strain and electric polarization. However, this effect is restricted to materials that lack inversion symmetry. In contrast, the flexoelectric effect […]

Deconfined quantum criticality in a frustrated Haldane chain with single-ion anisotropy

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Niels T. Pronk, Bowy M. La Rivière, Natalia Chepiga, , | Summary: We report a phase diagram of the antiferromagnetic spin-1 chain with nearest-neighbor Heisenberg and three-site interactions in the presence of single-ion anisotropy. We show that the Gaussian and Ising transitions that separate the topological Haldane […]

The reliability of hybrid functionals for accurate fundamental and optical gap prediction of bulk solids and surfaces

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Francisca Sagredo, María Camarasa-Gómez, Francesco Ricci, Aurélie Champagne, Leeor Kronik | Summary: Hybrid functionals have been considered insufficiently reliable for the prediction of band gaps in solids and surfaces. We revisit this issue with a new generation of optimally-tuned range-separated hybrid functionals, focusing on the reconstructed […]
