Intracavity frequency-doubled green vertical external cavity surface emitting laser

引用

Chinese Optics Letters 2008年第4期6卷 271-273页

作者：宋晏蓉张鹏张新平颜博霞周翊毕勇张志刚 college of applied sciences Beijing University of Technology Beijing 100022 Academy of Opto-Electronics Chinese Academy of sciences Beijing 100080 college of Electronic Engineering and computer Science Peking University Beijing 100871

An intracavity frequency-doubled vertical external cavity surface emitting laser （VECSEL） with green light is demonstrated. The fundamental frequency laser cavity consists of a distributed Bragg reflector （DBR） of the gain chip and an external mirror. A 12-mW frequency-doubled output has been reached at 540 nm with a nonlinear crystal LBO when the fundamental frequency output is 44 mW at 1080 nm. The frequency doubling efficiency is about 30%.

Screening Effect in Charge Qubit

引用

Communications in Theoretical Physics 2011年第7期56卷 74-78页

作者：华明肖骁高一波 college of applied sciences Beijing University of Technology

We study the influence of screening effect on quantum decoherence for charge qubit and the process of quantum information storage. When the flux produced by the circulating current in SQUID loop is considered, screening effect is formally characterized by a LC resonator. Using large-detuning condition and Fr6hlich transformation in the qubit-cavity-resonator system, we calculate the decoherenee factor for charge qubit and the effective qubit-cavity Hamiltonian. The decoherence factor owns a factorized structure, it shows that screening effect is a resource of decoherence for charge qubit. The effective Hamiltonian shows that the screening effect results in a frequency shift for charge qubit and a modified qubit-cavity coupling constant induced by a LC resonator.

Quantum Decoherence of Charge Qubit Coupled to Nonlinear Nanomechanical Resonator

引用

Communications in Theoretical Physics 2013年第11期60卷 531-534页

作者：陈诚高一波 college of applied sciences Beijing University of Technology

When the nonlinearity of nanomechanical resonator is not negligible, the quantum decoherenee of charge qubit is studied analytically. Using nonlinear Jaynes-Cummings model, one explores the possibility of being quantum data bus for nonlinear nanomechanical resonator, the nonlinearity destroys the dynamical quantum information-storage and maintains the revival of quantum coherence of charge qubit. With the calculation of decoherence factor, we demon- strate the influence of the nonlinearity of nanomechanical resonator on engineered decoherence of charge qubit.

DECAY ESTIMATES FOR ISENTROPIC COMPRESSIBLE MAGNETOHYDRODYNAMIC EQUATIONS IN BOUNDED DOMAIN

Acta Mathematica Scientia 2012年第6期32卷 2211-2220页

作者： Mohamed Ahmed Abdallah 江飞谭忠 School of Mathematical sciences Xiamen University college of Mathematics and computer Science Fuzhou University Institute of applied Physics and Computational Mathematics

In this paper, under the hypothesis that y is upper bounded, we construct a Lyapunov functional for the multidimensional isentropic compressible magnetohydrodynamic equations and show that the weak solutions decay exponentially to the equilibrium state in L2 norm. Our result verifies that the method of Daoyuan Fang, Ruizhao Zi and Ting Zhang I1] can be adapted to magnetohydrodynamic equations.

Ketogenic diet and cancer:multidimensional exploration and research

引用

Science China Life sciences 2025年

作者： Shiyun Wan Xiaoxue Zhou Feng Xie Fangfang Zhou Long Zhang The First Affiliated Hospital the Institutes of Biology and Medical Sciences Suzhou Medical College Soochow University School of Medicine Hangzhou City University Life sciences Institute and State Key Laboratory of Transvascular Implantation Devices of the Second Affiliated Hospital of Zhejiang University School of Medicine Zhejiang University The MOE Basic Research and Innovation Center for the Targeted Therapeutics of Solid Tumors The First Affiliated Hospital Jiangxi Medical College Nanchang University Cancer Center Zhejiang University

The ketogenic diet(KD) has attracted attention in recent years for its potential anticancer effects. KD is a dietary structure of high fat,moderate protein, and extremely low carbohydrate content. Originally introduced as a treatment for epilepsy, KD has been widely applied in weight loss programs and the management of metabolic diseases. Previous studies have shown that KD can potentially inhibit the growth and spread of cancer by limiting energy supply to tumor cells, thereby inhibiting tumor angiogenesis, reducing oxidative stress in normal cells, and affecting cancer cell signaling and other processes. Moreover, KD has been shown to influence T-cell-mediated immune responses and inflammation by modulating the gut microbiota, enhance the efficacy of standard cancer treatments, and mitigate the complications of chemotherapy. However, controversies and uncertainties remain regarding the specific mechanisms and clinical effects of KD as an adjunctive therapy for cancer. Therefore, this review summarizes the existing research and explores the intricate relationships between KD and cancer treatment.

Separability Criteria for Quantum Mixed States in Terms of Trace Norm

Chinese Physics Letters 2006年第7期23卷 1674-1675页

作者：赵慧 college of applied sciences Beijing University of Technology Beijing 100022

A new necessary conditions for separability of mixed states in bipartite and multipartite quantum systems of arbitrary dimensions are presented. This method requires only a few local measurements. If a quantum state in a bipartite （or multipartite） system of arbitrary dimension is separable, we show that the trace norm of a constructive matrix is less than or equal to 1.

Optical Erasure Characteristics of Holograms in Batch Thermal-Fixing

引用

Chinese Physics Letters 2006年第10期23卷 2749-2752页

作者：江竹青陶世荃袁韡刘国庆王大勇 college of applied sciences Beijing University of Technology Beijing 100022

The optical erasure dynamics in a batch-thermal fixing scheme of holographic storage in photorefractive crystals is investigated theoretically and experimentally. The inter-batch optical erasure time constant τF is introduced to specify the optical erasure to compensated gratings, and measured in a sophisticated experiment. The experimental result shows that τF is much longer than the intra-batch optical erasure time constant τE. The difference between τFand τE is fundamental for enhancing nonvolatile storage density.
