Accurate non-empirical range-separated hybrid van der Waals density functional for complex molecular problems, solids, and surfaces

Posted by klaurent Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Vivekanand Shukla, Yang Jiao, Jung-Hoon Lee, Elsebeth Schroder, Jeffrey B. Neaton | Summary: We introduce a new, general-purpose, range-separated hybrid van der Waals density ph{functional, termed vdW-DF-ahbr,} within the non-empirical vdW-DF method [JPCM 32, 393001 (2020)]. It combines correlation from vdW-DF2 with a screened Fock exchange […]

Nonreciprocal Infrared Absorption via Resonant Magneto-optical Coupling to InAs

Posted by dbos Caltech

Kavli Affiliate: Harry Atwater | First 5 Authors: Komron Shayegan, Bo Zhao, Yonghwi Kim, Shanhui Fan, Harry Atwater | Summary: Nonreciprocal elements are a vital building block of electrical and optical systems. In the infrared regime, there is a particular interest in structures that break reciprocity because their thermal absorptive (and emissive) properties should not […]

An extended mixed finite element method for elliptic interface problems

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Pei Cao, Jinru Chen, Feng Wang, , | Summary: In this paper, we propose an extended mixed finite element method for elliptic interface problems. By adding some stabilization terms, we present a mixed approximation form based on Brezzi-Douglas-Marini element space and the piecewise constant function space, and […]

Experimentally ruling out joint reality based on operational completeness

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Qiuxin Zhang, Yu Xiang, Xiaoting Gao, Chenhao Zhu, Yuxin Wang | Summary: Whether the observables of a physical system admit real values is of fundamental importance to a deep understanding of nature. In this work, we report a device-independent experiment to confirm that the joint reality of […]

Character of the “normal state” of the nickelate superconductors

Posted by klaurent Cornell

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Kyuho Lee, Bai Yang Wang, Motoki Osada, Berit H. Goodge, Tiffany C. Wang | Summary: The occurrence of superconductivity in proximity to various strongly correlated phases of matter has drawn extensive focus on their normal state properties, to develop an understanding of the state from which […]

Imaging Atomic-Scale Chemistry from Fused Multi-Modal Electron Microscopy

Posted by Cornell

Kavli Affiliate: Richard D. Robinson | First 5 Authors: Jonathan Schwartz, Zichao Wendy Di, Yi Jiang, Alyssa J. Fielitz, Don-Hyung Ha | Summary: Efforts to map atomic-scale chemistry at low doses with minimal noise using electron microscopes are fundamentally limited by inelastic interactions. Here, fused multi-modal electron microscopy offers high signal-to-noise ratio (SNR) recovery of […]

New criterions on nonexistence of periodic orbits of planar dynamical systems and their applications

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Hebai Chen, Hao Yang, Rui Zhang, Xiang Zhang, | Summary: Characterizing existence or not of periodic orbit is a classical problem and it has both theoretical importance and many real applications. Here, several new criterions on nonexistence of periodic orbits of the planar dynamical system $dot x=y,~dot […]
