Lifetime Limited and Tunable Quantum Light Emission in h-BN via Electric Field Modulation

Posted by klaurent Caltech

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Hamidreza Akbari, Souvik Biswas, Pankaj K. Jha, Joeson Wong, Benjamin Vest | Summary: Color centered-based single photon emitters in hexagonal boron nitride (h-BN) have shown promising photophysical properties as sources for quantum light emission. Despite significant advances towards such a goal, achieving lifetime-limited quantum light emission […]

A method to computationally screen for tunable properties of crystalline alloys

Posted by klaurent Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Rachel Woods-Robinson, Matthew K. Horton, Kristin A. Persson, , | Summary: Conventionally, high-throughput computational materials searches start from an input set of bulk compounds extracted from material databases, and this set is screened for candidate materials for specific applications. In contrast, many functional materials, and especially […]

How Material Heterogeneity Creates Rough Fractures

Posted by dbos Harvard

Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Will Steinhardt, Shmuel M. Rubinstein, , , | Summary: Fractures are a critical process in how materials wear, weaken, and fail whose unpredictable behavior can have dire consequences. While the behavior of smooth cracks in ideal materials is well understood, it is assumed that for real, […]

Self-Supervised Contrastive Pre-Training For Time Series via Time-Frequency Consistency

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Ziyuan Zhao, Theodoros Tsiligkaridis, Marinka Zitnik, | Summary: Pre-training on time series poses a unique challenge due to the potential mismatch between pre-training and target domains, such as shifts in temporal dynamics, fast-evolving trends, and long-range and short cyclic effects, which can lead to poor […]
