英国苏塞克斯大学 EPSRC全奖博士职位 您对计算物理/数学或科学计算感兴趣吗？ EPSRC 化学博士：开发少粒子量子系统的张量结构方法（2022 年）。 从 2022 年 10 月 1 日起，在 Hazel Cox 教授的指导下，可以获得 EPSRC 博士生奖学金（42 个月）， 化学，生命科学学院，适合在化学、数学、物理方面具有深厚学术背景的学生。 你得到什么。博士职位由 EPSRC 全额资助。资金包括全额英国或国际学费、研究培训补助金 （每年 1650 英镑）和 3.5 年的 UKRI 费率（目前为 16,062 英镑）的津贴。 奖励类型： 博士研究生研究 博士项目：开发少粒子量子系统的张量结构方法 （Development of tensor-structured methods for few-particle quantum systems） 张量结构数值方法已成为科学研究的热门话题，因为它们具有巨大的变革潜力由于多线性代数的强大功能，需要使用矩阵进行计算的任何领域，计算成本崩溃和收缩计算时间。在物理和化学界，密度矩阵正在推动一场量子化学革命重整化组 (DMRG) 方法。在数学中，一个重要的焦点是开发张量分解方法和张量积近似。这个跨学科项目将汇集这两个科学世界，以开发强大的新张量结构的数值方法能够极其精确地模拟少粒子库仑系统。考虑少粒子时系统，有可能超越传统量子化学中的标准近似，并处理电子的相关运动和原子核处于平等地位。这提供了高精度的结果，并有助于计算更多涉及 μ 子的奇异系统（类似电子但更重）或正电子（类似核但更轻）。因此，该项目的目的是开发一种新的张量结构方法通过显式处理所有粒子的相关运动来求解少数粒子系统的与时间无关的薛定谔方程，使用最合适的张量分解进行高精度计算。拟议的研究包括三个项目。首先是通过以合适的张量格式重铸算子和波函数，然后减少多维张量来开发该方法到特定的低秩张量网络格式。二是考虑计算成本（CPU时间，计算机内存需求、缩放等）与准确性（由于低秩张量分解导致的信息丢失）。最后，新开发的张量结构方法将用于研究原子系统在稳定性临界点的行为。 候选人必须拥有或期望获得至少 2:1 的本科学位。 硕士学位将是有利的。你的学术背景应该是化学、数学、物理或相关学科领域。 如果您具有其他专业资格或同等地位的经验，您也可能会被考虑担任该职位。 英语不是他们的第一语言的候选人将要求雅思（或同等学历）总分不低于 6.5，任何部分不低于 6.0。 请查看我们的招生页面了解更多信息：化学博士：苏塞克斯大学 https://www.sussex.ac.uk/study/phd/degrees/chemistry-phd 截止日期：2022年5月13日23:45 （英国时间， 2022年5月14日06:45） 请通过如何申请博士学位提交正式申请：博士学位：与我们一起学习：苏塞克斯大学，并上传以下证明文件： • 个人陈述（无需研究计划）， •简历， • BSc/MSc 学位成绩单和证书， • 学术信笺上的两份参考资料 • 如果需要，提供英语语言能力证明文件。 在申请系统上选择学习计划 - 博士化学，以及 2022 年 9 月的入学日期。请确保您在资金部分注明“EPSRC DTP 2022”，并在出现提示时注明主管的姓名。 联系我们有关申请流程的查询，请联系 Emma Chorley： lifesci-rec@sussex.ac.uk 有关该项目的查询，请联系 Hazel Cox教授： H.Cox@sussex.ac.uk 链接：https://www.sussex.ac.uk/study/f ... cle-quantum-systems EPSRC-FUNDED PHD POSITION AT UNIVERSITY OF SUSSEX, UNITED KINGDOM Do you have an interest in computational physics/mathematics or scientific computing? EPSRC PhD in Chemistry: Development of tensor-structured methods for few-particle quantum systems (2022). An EPSRC PhD studentship (42 months) is available from 1st October 2022, under the supervision of Prof. Hazel Cox, Chemistry, School of Life Sciences, for a student with a strong academic background in chemistry, mathematics, physics or a related subject area. What you get. The PhD position is fully funded by EPSRC. Funding includes full UK or International tuition fees, a research training grant (£1650 per annum) and a stipend at UKRI rates (currently £16,062pa) for 3.5 years. Type of award. Postgraduate Research PhD project. Development of tensor-structured methods for few-particle quantum systems Tensor-structured numerical methods have emerged as a hot topic in scientific research as they have the potential to transform dramatically any field that requires computation using matrices due to the power of multilinear algebra, collapsing computational costs, and shrinking computational time. Within the physics and chemistry communities, a quantum chemistry revolution is being driven by the Density Matrix Renormalization Group (DMRG) methods. Within mathematics, a significant focus has been on developing tensor decomposition methods and tensor product approximations. This interdisciplinary project will bring together these two scientific worlds to develop powerful new tensor-structured numerical methods capable of modelling extremely accurately few-particle Coulomb systems. When considering few-particle systems, it is possible to go beyond the standard approximations in conventional quantum chemistry and treat the correlated motion of electrons and nuclei on an equal footing. This provides high accuracy results and facilitates the calculation of more exotic systems involving muons (electron-like but heavier) or positrons (nuclear-like but lighter). Therefore, the aim of this project is to develop a new tensor-structured method for solving the time-independent Schrödinger equation for few particle systems by treating explicitly the correlated motion of all the particles, using the most appropriate tensor decompositions for high accuracy calculations. The proposed research consists of three projects. The first is to develop the method by recasting the operators and wavefunctions in a suitable tensor format and then reducing the multi-dimensional tensors to a specific low-rank tensor network format. The second is to implement and optimise the method considering computation cost (CPU time, computer memory requirements, scaling, etc.) against accuracy (information loss due to low-rank tensor decomposition). Finally, the newly developed tensor-structured method will be used to study the behaviour of atomic systems at the critical point for stability. Eligibility. Candidates must have or expect to obtain a minimum 2:1 undergraduate degree. An MSc degree will be advantageous. Your qualification should be in chemistry, mathematics, physics or a related subject area. You may also be considered for the position if you have other professional qualifications or experience of equivalent standing. Candidates for whom English is not their first language will require an IELTS (or equivalent) score of 6.5 overall, with not less than 6.0 in any section.
