We propose a scaling law for anomalous Hall effect in ferromagnetic thin films. Our approach distinguishes multiple scattering sources, namely, bulk impurity, phonon for Hall resistivity, and most importantly the rough surface contribution to longitudinal resistivity. In stark contrast to earlier laws that rely on temperature- and thickness-dependent fitting coefficients, this scaling law fits the recent experimental data excellently with constant parameters that are independent of temperature and film thickness, strongly indicating that this law captures the underlying physical processes. Based on a few data points, this scaling law can even fit all experimental data in full temperature and thickness range. We apply this law to interpret the experimental data for Fe, Co, and Ni and conclude that (i) the phonon-induced skew scattering is unimportant as expected; (ii) contribution from the impurity-induced skew scattering is negative; (iii) the intrinsic (extrinsic) mechanism dominates in Fe (Co), and both the extrinsic and intrinsic contributions are important in Ni.

Metal–organic frameworks (MOFs) with high surface area and tunable chemical structures have attracted tremendous attention. Recently, the utilization of solar energy for CO 2 conversion to produce valuable chemicals or fuels has become extremely appealing. The interior of MOFs can be designed to have defects, heteroatoms and embedded nanoscale metal catalysts for the development of CO 2 conversion. In this review, the recent development of MOFs‐based catalysts for CO 2 conversion reactions, including photocatalysis and electrocatalysis are summarized. In particular, the preparation and mechanism of CO 2 conversion‐based MOFs are discussed. The examples are expected to provide deeper understanding in preparing highly active and stable MOFs‐based CO 2 conversion materials.

Gold (Au) nanoparticles have been attractive for centuries for their vibrant appearance enhanced by their interaction with sunlight. Nowadays, there have been tremendous research efforts to develop them for high-tech applications including therapeutic agents, sensors, organic photovoltaics, medical applications, electronics and catalysis. However, there remains to be a challenge to fabricate a monolayer Au coating with complete coverage in controlled fashion. Here we present a facile method to deposit a uniform Au monolayer (ML) film on the [BMIM][PF 6 ] ionic liquid substrate using an electrochemical deposition process. It demonstrates that it is feasible to prepare a solid phase coating on the liquid-based substrate. Moreover, the thickness of the monolayer coating can be controlled to a layer-by-layer accuracy.

A quantum spin liquid with a Z2 topological order has long been thought to be important for the application of quantum computing and may be related to high-temperature superconductivity [1–3]. While a two-dimensional kagome antiferromagnet may host such a state, strong experimental evidences are still lacking [4–9]. Here we show that the spin excitations from the kagome planes in magnetically ordered Cu4(OD)6FBr and non-magnetically ordered Cu3Zn(OD)6FBr are similarly gapped although the content of inter-kagome-layer Cu2+ ions changes dramatically. This suggests that the spin triplet gap and continuum of the intrinsic kagome antiferromagnet are robust against the interlayer magnetic impurities. Our results show that the ground state of Cu3Zn(OD)6FBr is a gapped quantum spin liquid with Z2 topological order. Copyright © 2017, The Authors. All rights reserved.

Quantum simulation promises to have wide applications in many fields where problems are hard to model with classical computers. Various quantum devices of different platforms have been built to tackle the problems in, say, quantum chemistry, condensed matter physics, and high-energy physics. Here, we report an experiment towards the simulation of quantum gravity by simulating the holographic entanglement entropy. On a six-qubit nuclear magnetic resonance quantum simulator, we demonstrate a key result of Anti-de Sitter/conformal field theory(AdS/CFT ) correspondence-the Ryu-Takayanagi formula is demonstrated by measuring the relevant entanglement entropies on the perfect tensor state. The fidelity of our experimentally prepared the six-qubit state is 85.0% via full state tomography and reaches 93.7%if the signal-decay due to decoherence is taken into account. Our experiment serves as the basic module of simulating more complex tensor network states that exploring AdS/CFT correspondence. As the initial experimental attempt to study AdS/CFT via quantum information processing, our work opens up new avenues exploring quantum gravity phenomena on quantum simulators.

Chirality sorting using two-wave-interference–induced lateral optical force

Physical Review A 2016年第5期93卷 053833-053833页

作者： Huajin Chen Chenghua Liang Shiyang Liu Zhifang Lin State Key Laboratory of Surface Physics (SKLSP) and Department of Physics Fudan University Shanghai 200433 China School of Electrical and Information Engineering Guangxi University of Science and Technology Liuzhou Guangxi 545006 China Institute of Information Optics Zhejiang Normal University Jinhua Zhejiang 321004 China Key Laboratory of Micro and Nano Photonic Structures (MOE) Fudan University Shanghai 200433 China Collaborative Innovation Center of Advanced Microstructures Fudan University Shanghai 200433 China

We demonstrate that a lateral optical force (LOF) can be induced on chiral nanoparticles immersed in the two interfering plane waves. The LOF can push the chiral nanoparticle sideways, in the direction relying on the helicity of the particle as well as the phase difference between two waves. Analytical theory reveals that the LOF comes mostly from the direct coupling of the optical vorticity with the particle chirality. In particular, the LOF has a magnitude comparable to the gradient force and radiation pressure when the particle chirality is sufficiently large. The LOF may serve for chirality sorting due to its unusual properties and also provide an opportunity for passive chiral spectroscopy.
