[交流] 德国卡塞尔大学University of Kassel招收实验物理/光学方向 CSC博士/博士后

德国卡塞尔大学University of Kassel招收实验物理/光学方向 CSC博士/博士后

简介帮老板招1-2名CSC博士或者博士后。主要研究方向是不同系统中的光与物质相互作用。老板很年轻，人很nice，而且极具创新精神。实验室在两年前刚刚建立，组里是英语工作环境，大部分成员都有多元化背景。

Project 1: Trapped ions for quantum thermodynamics

The project aims to exploit the laws of thermodynamics and realize thermo-machines at the ultimate limit of a single atom [1,2,3]. Utilizing state-of-the-art techniques in single ion trapping and laser state manipulation, our previous experiments have demonstrated a full Otto-cycle heat engine using a single Calcium ion in a linear Paul trap [1]. This experiment opened a new realm for investigating thermodynamics at the single-atom level and in the quantum regime. Throughout this project we seek to provide experimental answers to many interesting questions when thermodynamics meet the quantum world.

Project 2: Color centers for quantum sensing

The project is focused on studying nitrogen vacancy centers in diamond for the purpose of quantum sensing. Color centers possess outstanding properties as quantum systems with respect to the simplicity of application outside the research lab, such as high photostability and operation at room temperature. Efforts are currently devoted to devising new sensing schemes and apply them to examples of probes like magnetic nanostructures. Using such systems as quantum memory is also considered. Indeed, such a memory coupled to a sensor enables one to improve its performance thanks to longer coherent interaction with the sensing field.

Project 3: Rydberg atoms for chirality detection

The central goal is to realize nondestructive chirality identification of molecules using cold rubidium atoms inside a magneto-optical trap which has the potential to push the sensitivity limits beyond current state of the art of the identification techniques. The long term goal of this project is to push chiral identification to the single molecule limit by using the extreme properties of Rydberg states of alkali atoms for ultraprecise quantum sensing of chirality.
