Quantum materials and technologies are becoming increasingly relevant as we search for new and exciting physics and exploit this to develop novel and useful devices. As we test our understanding, we can learn how to use materials in numerous ways depending upon how we manipulate the same material. This PhD will explore the properties of dilute Ho ion containing materials to probe new physics, this requires an understanding of the underlying population of the quantised energy levels; in parallel we will use this knowledge to develop thermal management for dilution fridges, which are the bedrock technology of superconducting quantum computers. The PhD project will use a unique high frequency magnetic a.c. susceptometer to probe the quantum state populations of the Ho magnetic ions which we will learn how to manipulate with RF techniques commonly used by the quantum computing community. In principle we will be able to induce interactions between the isolated Ho ions and understand how the dynamics of the correlated Ho ions are modified. We will develop new physics and new techniques to probe the quantum states. We will also use our knowledge of these states to implement a thermal management system into a unique self contained dilution unit - this will require a detailed knowledge of the states which contribute to the specific heat of the Ho ion containing system. The PhD will take 5 years as it is part time starting between April 23 and Oct 23, with 50% of the time spent in Cardiff and 50% of the time spent on the development/production line at Chase Research Cryogenics in Sheffield.

随着我们寻找新的和令人兴奋的物理并利用它来开发新的和有用的设备，量子材料和技术正变得越来越重要。当我们测试我们的理解能力时，我们可以学习如何以多种方式使用材料，这取决于我们如何处理相同的材料。这个PHD将探索稀薄Ho离子材料的性质以探索新的物理，这需要了解量子能级的潜在群体；同时，我们将利用这些知识来开发稀释式冰箱的热管理，这是超导量子计算机的基础技术。博士项目将使用一种独特的高频磁交流。我们将学习如何使用量子计算界常用的射频技术来操纵Ho磁性离子的量子态布居。原则上，我们将能够诱导孤立的Ho离子之间的相互作用，并了解相关Ho离子的动力学是如何改变的。我们将发展新的物理和新的技术来探测量子态。我们还将利用我们对这些状态的了解，将热管理系统实施到一个独特的自容式稀释单元中-这将需要详细的状态知识，这些状态对含Ho离子的系统的比热有贡献。博士学位将需要5年时间，因为它是从4月23日到10月23日的兼职，50%的时间在加的夫，50%的时间在谢菲尔德大通研究低温公司的开发/生产线上。
