拓扑材料 固体物理学 量子霍尔效应
2023/4/17
物理学中许多概念是在不断地发展中的。例如人们对光、电子等的理解与它们刚开始出现时的概念已经发生了许多进化，而固体物理学中的“绝缘体”概念也是如此。近三十年来，量子霍尔效应的相关研究不仅催生了拓扑序这一新的物相分类，也推动了拓扑绝缘体这一新兴研究领域的诞生和发展。随着量子自旋霍尔效应、拓扑晶体绝缘体等工作的后续展开，人们意识到对称性可以带来新的拓扑态，同时也不断地在“普通绝缘体”中发现新的拓扑态。这...

Circular Sound Wave Scattering Derivation for Acoustic Cloak Detection
Circular Sound Wave Scattering Derivation Acoustic Cloak Detection Classical Physics
2012/5/29
In this Letter we develop analytical formulations to describe sound scattering in lossless medium due to 2D circular wave incident on an acoustic cloak. A perfect acoustic cloak is reflectionless and ...
A vector diffranction medel has been applied to analyze CAD readout of MSR disks.Numerical results indicate that the read power is optimized with an aperture of the same size as the recorded mark.CNR ...
Magnetically induced superresolution by center aperture detection (MSR-CAD) using pulsed and conventional dcshemes were applied to magneto-optical disks to quantitatively enaluate readout performances...
A Novel Direct Detection Microwave Photonic Vector Modulation Scheme for Radio-Over-Fiber System
2011/11/22
This letter demonstrates the feasibility of a novel direct detection microwave photonic vector modulation scheme for the radio-over-fiber (RoF) system. Unlike the traditional double-sideband with opti...
Negative Backaction Noise in Interferometric Detection of a Microlever
Negative Backaction Noise Interferometric Detection Microlever
2011/8/11
Abstract: Interferometric detection of mirror displacements is intrinsically limited by laser shot noise. In practice, however, it is often limited by thermal noise. Here we report on an experiment pe...
