Comparing self-consistent GW and vertex corrected G0W0 (G0W0Γ) accuracy for molecular ionization potentials

Posted by dbos Berkeley

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Ming Wen, Vibin Abraham, Gaurav Harsha, Avijit Shee, K. Birgitta Whaley | Summary: We test the performance of self-consistent GW and several representative implementations of vertex corrected G0W0 (G0W0{Gamma}). These approaches are tested on benchmark data sets covering full valence spectra (first ionization potentials and some inner […]

Third harmonic generation enhancement and wavefront control using a local high-Q metasurface

Posted by dbos Caltech

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Claudio U. Hail, Lior Michaeli, Harry A. Atwater, , | Summary: High quality factor optical nanostructures provide great opportunity to enhance nonlinear optical processes such as third harmonic generation. However, the field enhancement in these high quality factor structures is typically accompanied by optical mode nonlocality. […]

FOAL: Fine-grained Contrastive Learning for Cross-domain Aspect Sentiment Triplet Extraction

Posted by dbos Berkeley

Kavli Affiliate: Ting Xu | First 5 Authors: Ting Xu, Zhen Wu, Huiyun Yang, Xinyu Dai, | Summary: Aspect Sentiment Triplet Extraction (ASTE) has achieved promising results while relying on sufficient annotation data in a specific domain. However, it is infeasible to annotate data for each individual domain. We propose to explore ASTE in the […]

Gate modulation of the hole singlet-triplet qubit frequency in germanium

Posted by dbos Delft

Kavli Affiliate: Menno Veldhorst | First 5 Authors: John Rooney, Zhentao Luo, Lucas E. A. Stehouwer, Giordano Scappucci, Menno Veldhorst | Summary: Spin qubits in germanium gate-defined quantum dots have made considerable progress within the last few years, partially due to their strong spin-orbit coupling and site-dependent $g$-tensors. While this characteristic of the $g$-factors removes […]

Entanglement buffering with two quantum memories

Posted by dbos Delft

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Bethany Davies, Álvaro G. Iñesta, Stephanie Wehner, , | Summary: Quantum networks crucially rely on the availability of high-quality entangled pairs of qubits, known as entangled links, distributed across distant nodes. Maintaining the quality of these links is a challenging task due to the presence of time-dependent […]
