Direct Comparison of Magnetic Penetration Depth in Kagome Superconductors AV$_3$Sb$_5$ (A = Cs, K, Rb)

Posted by dbos Cornell

Kavli Affiliate: Katja C. Nowack | First 5 Authors: Austin Kaczmarek, Andrea Capa Salinas, Stephen D. Wilson, Katja C. Nowack, | Summary: We report measurements of the local temperature-dependent penetration depth, $lambda(T)$, in the Kagome superconductors AV$_3$Sb$_5$ (A = Cs, K, Rb) using scanning superconducting quantum interference device (SQUID) microscopy. Our results suggest that the […]

Picosecond expansion in LaAlO3 resonantly driven by infrared-active phonons

Posted by dbos Cornell

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Jakob Gollwitzer, Jeffrey Z. Kaaret, Y. Eren Suyolcu, Guru Khalsa, Rylan C. Fernandes | Summary: We investigate the ultrafast structural dynamics of LaAlO3 thin films driven by short mid-infrared laser pulses at 20 THz. Time-resolved X-ray diffraction reveals an immediate lattice expansion and an acoustic breathing […]

A tensor network formulation of Lattice Gauge Theories based only on symmetric tensors

Posted by dbos Delft

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Manu Canals, Natalia Chepiga, Luca Tagliacozzo, , | Summary: The Lattice Gauge Theory Hilbert space is divided into gauge-invariant sectors selected by the background charges. Such a projector can be directly embedded in a tensor network ansatz for gauge-invariant states as originally discussed in [Phys. Rev. B […]

The Interplay Between Electron Localization, Magnetic Order, and Jahn-Teller Distortion that Dictates LiMnO$_2$ Phase Stability

Posted by dbos Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Ronald L. Kam, Luca Binci, Aaron D. Kaplan, Kristin A. Persson, Nicola Marzari | Summary: The development of Mn-rich cathodes for Li-ion batteries promises to alleviate supply chain bottlenecks in battery manufacturing. Challenges in Mn-rich cathodes arise from Jahn-Teller (JT) distortions of Mn$^{3+}$, Mn migration, and […]

Kramers-protected hardware-efficient error correction with Andreev spin qubits

Posted by dbos Delft

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Haoran Lu, Isidora Araya Day, Anton R. Akhmerov, Bernard van Heck, Valla Fatemi | Summary: We propose an architecture for bit flip error correction of Andreev spins that is protected by Kramers’ degeneracy. Specifically, we show that a coupling network of linear inductors results in a […]

A two-dimensional 10-qubit array in germanium with robust and localised qubit control

Posted by dbos Delft

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Valentin John, Cécile X. Yu, Barnaby van Straaten, Esteban A. Rodríguez-Mena, Mauricio Rodríguez | Summary: Quantum computers require the systematic operation of qubits with high fidelity. For holes in germanium, the spin-orbit interaction allows for textit{in situ} electric fast and high-fidelity qubit gates. However, the interaction also […]
