| 2 | 压缩算符在自由标量场理论中的推广显示文摘引入了一种在量子场论中构造压缩算符的办法:考虑两个具有不同质量的同一标量场的自由哈密顿量,通过博戈留波夫变换,导出广义压缩算符,该算符把一个基态映射到另一个。该算符作用的有效性分别在量子场论的狄拉克表象和薛定谔泛函表象中得到了验证。我们相信,在任意实标量场理论中,只要存在两组以线性变换联系起来的生成湮灭算符,压缩算符就被类似的方法找到。 | 周遥 Jarah Evslin | 2020 | 原子核物理评论2020,37,2: | 0 |
| 3 | 磁单极研究显示文摘Gauge invariance implies that if the Gauss constraint in Yang-Mills(YM)or QCD is satisfied at an initial time,then it will be satisfied at all future times.However in numerical simulations of real time evolution,the small errors inevitably lead to a small deviation from the Gauss constraint,which exponentially grows,ruining the validity of the simulation.The result is that simulations must either be very short or else must restore the Gauss constraint at each step,which is very time-consuming.In either case,only the simplest simulations of real time evolution are possible. | Jarah Evslin | 2018 | IMP & HIRFL Annual Report2018,,1: | 0 |
| 4 | 哈勃常熟移动问题显示文摘One of the hottest and most intriguing recent topics in cosmology has been the tension[1]between the cosmic expansion rate as measured using the local Universe as compared with that determined from the Cosmic Microwave Background(CMB).This tension has been steadily growing for the past 3 years,and is perhaps the strongest evidence of a failure of the standardΛCDM cosmological model. | Jarah Evslin | 2018 | IMP & HIRFL Annual Report2018,,1: | 0 |
| 5 | Origin of Nucleon Mass and J/ψ Near-Threshold Photo-Production o the Proton显示文摘Nucleon(proton or neutron)is the main building block of the visible matter,which contributes around 99% of the mass of the observable universe.However,we still do not know how do its basic properties arise from,such as its mass and its spin. | Wang Rong Chen Xurong Jarah Evslin | 2019 | IMP & HIRFL Annual Report2019,,1: | 0 |
| 6 | 1-21 Spallation Isotope Backgrounds at JUNO显示文摘The JUNO experiment[1] is the successor to Daya Bay. It envisages the construction of the world’s largest scintillator detector, which it will use primarily to detect reactor neutrinos, with the goal of determining the neutrino mass hierarchy.The cosmogenic muons, i.e. the muons created by the interaction of cosmic rays in the atmosphere, provide a potentially dangerous background. They can interact with the 12C inside the detector creating, among other things, the isotopes 9Li and 8He; some of their decays can emit a neutron, mimicking the double coincidence used to identify the IBD reactor neutrino signal. | Emilio Ciuffoli Jarah Evslin | 2015 | IMP & HIRFL Annual Report2015,,1: | 0 |
| 7 | 1-24 Global Two-monopoles显示文摘Global two-monopoles are unstable in their simplest formulation. We construct a model with a metric-like prefactor which we show can stabilize the global two-monopoles. The stabilizing construction is realized with a Skyrme sector where the metric-like prefactor is a function of the Skyrmion profile. | Sven Bjarke Gudnason Jarah Evslin | 2015 | IMP & HIRFL Annual Report2015,,1: | 0 |
| 8 | 基于氘铍反应寻找惰性中微子的新的同位素静止系衰变方案显示文摘Neutrino oscillations have been observed in solar and atmosphere neutrino experiments[1,2],and confirmed independently by accelerator and reactor neutrino experiments[3-5].However,some anomalies have been observed in neutrino experiments with different sources,detector principles and detection channels[6-13],which can not be accommodated within the standard three-flavour neutrino paradigm.These anomalous results may be a sign of further new physics beyond Standard Model and currently their most popular interpretation is the existence of sterile neutrino states with masses at the eV scale.Sterile neutrino states are a key issue in searches for new physics beyond the Standard Model,and their existence and properties would also have important implications in astrophysics and cosmology. | Chen Liangwen Cai Hanjie Emilio Ciuffoli Jarah Evslin Zhang Sheng Chen Xurong Yang Lei | 2017 | IMP & HIRFL Annual Report2017,,1: | 0 |
| 9 | Innovative design for a portable hybrid system of hydroponic and microalgae to produce food and biofuels显示文摘This study investigates an innovative hybrid system that combines hydroponics and microalgae in a compact portable shipping container.This container is divided into two parts;one contains the microalgae system and the other contains the hydroponic system.This combined system works by dividing the 24 hours into 12 hours of light and 12 hours of dark for each part.Both parts are connected using light-impermeable pipes that pass carbon dioxide from the dark side to the lit side and oxygen from the lit side to the dark side.In this paper,the authors developed a validated mathematical model for hydroponic and microalgae to evaluate the system’s performance.Results found by the model show the optimum parameters for the split photobioreactor and hydroponic system.The first investigated parameter is the sparger diameter for split the photobioreactor and the second is the number of plants that give the better and optimum result.The optimum modelling design for the combined hydroponic and microalgae system was using 100 plants for lettuce and three photobioreactors with a 0.009-m diameter for sparger to a photobioreactor system with an area of 15.6 m^(2). | Ammar Alkhalidi Hala Jarah Mohamad K.Khawaja | 2022 | Clean Energy2022,6,3: | 0 |
| 10 | Faster than Light Neutrinos显示文摘In September,the OPERA experiment in Italy claimed to have observed neutrinos which travel faster than light.Strong experimental constraints are placed by neutrinos observed from the supernova SN1987A and from various terrestrial and astrophysical measurements of synchrotron radiation.Ⅰwill review the many experimental and theoretical challenges faced by any theory which attempts to explain this result,and speculate on just which theories may succeed. | Jarah Evslin | 2011 | 前沿科学2011,5,4: | 0 |
