Nonlocal screening dictates the radiative lifetimes of excitations in lead halide perovskites

Kavli Affiliate: David T. Limmer | First 5 Authors: Yoonjae Park, Amael Obliger, David T. Limmer, , | Summary: We use path integral molecular dynamics simulations and theory to elucidate the interactions between charge carriers, as mediated by a lead halide perovskite lattice. We find that the charge-lattice coupling of MAPbI$_3$ results in a repulsive […]

Embracing Single Stride 3D Object Detector with Sparse Transformer

Kavli Affiliate: Feng Wang | First 5 Authors: Lue Fan, Ziqi Pang, Tianyuan Zhang, Yu-Xiong Wang, Hang Zhao | Summary: In LiDAR-based 3D object detection for autonomous driving, the ratio of the object size to input scene size is significantly smaller compared to 2D detection cases. Overlooking this difference, many 3D detectors directly follow the […]

Benchmarking the performance of DFT functionals for absorption and fluorescence spectra of EGFR inhibitor AG-1478 using TD-DFT

Kavli Affiliate: Feng Wang | First 5 Authors: Sallam Alagawani, Vladislav Vasilyev, Feng Wang, , | Summary: Optical spectra (UV-vis and fluorescence) are sensitive to the chemical environment and conformation of fluorophores and therefore, are ideal probes for their conformation and solvent responses. Tyrosine kinase inhibitors (TKI) such as AG-1478 of epidermal growth factor receptor […]

Using principal stratification in analysis of clinical trials

Kavli Affiliate: Xiang Zhang | First 5 Authors: Ilya Lipkovich, Bohdana Ratitch, Yongming Qu, Xiang Zhang, Mingyang Shan | Summary: The ICH E9(R1) addendum (2019) proposed principal stratification (PS) as one of five strategies for dealing with intercurrent events. Therefore, understanding the strengths, limitations, and assumptions of PS is important for the broad community of […]

Optimizing frequency allocation for fixed-frequency superconducting quantum processors

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Alexis Morvan, Larry Chen, Jeffrey M. Larson, David I. Santiago, Irfan Siddiqi | Summary: Fixed-frequency superconducting quantum processors are one of the most mature quantum computing architectures with high-coherence qubits and low-complexity controls. However, high-fidelity multi-qubit gates pose tight requirements on individual qubit frequencies in these processors […]
