Synthesis and electronic properties of Nd$_{n+1}$Ni$_{n}$O$_{3n+1}$ Ruddlesden-Popper nickelate thin films

Posted by klaurent Cornell

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Grace A. Pan, Qi Song, Dan Ferenc Segedin, Myung-Chul Jung, Hesham El-Sherif | Summary: The rare-earth nickelates possess a diverse set of collective phenomena including metal-to-insulator transitions, magnetic phase transitions, and, upon chemical reduction, superconductivity. Here, we demonstrate epitaxial stabilization of layered nickelates in the Ruddlesden-Popper […]

SRGA J181414.6-225604: A new Galactic symbiotic X-ray binary outburst triggered by an intense mass loss episode of a heavily obscured Mira variable

Posted by klaurent MIT

Kavli Affiliate: Robert Simcoe | First 5 Authors: Kishalay De, Ilya Mereminskiy, Roberto Soria, Charlie Conroy, Erin Kara | Summary: We present the discovery and multi-wavelength characterization of SRGA J181414.6-225604, a Galactic hard X-ray transient discovered during the ongoing SRG/ART-XC sky survey. Using data from the Palomar Gattini-IR survey, we identify a spatially and temporally […]

Topological Entanglement Stabilization in Superconducting Quantum Circuits

Posted by klaurent Delft

Kavli Affiliate: Eliska Greplova | First 5 Authors: Guliuxin Jin, Eliska Greplova, , , | Summary: Topological properties of quantum systems are one of the most intriguing emerging phenomena in condensed matter physics. A crucial property of topological systems is the symmetry-protected robustness towards local noise. Experiments have demonstrated topological phases of matter in various […]

Say NO to Optimization: A Non-Orthogonal Quantum Eigensolver

Posted by klaurent Berkeley

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Unpil Baek, Diptarka Hait, James Shee, Oskar Leimkuhler, William J. Huggins | Summary: A balanced description of both static and dynamic correlations in electronic systems with nearly degenerate low-lying states presents a challenge for multi-configurational methods on classical computers. We present here a quantum algorithm utilizing the […]

Impartial Selection with Additive Guarantees via Iterated Deletion

Posted by dbos Berkeley

Kavli Affiliate: Felix Fischer | First 5 Authors: Javier Cembrano, Felix Fischer, David Hannon, Max Klimm, | Summary: Impartial selection is the selection of an individual from a group based on nominations by other members of the group, in such a way that individuals cannot influence their own chance of selection. For this problem, we […]
