The University of Exeter’s College of Engineering, Mathematics and Physical Sciences, is inviting applications for a fully funded PhD studentship to commence in October 2020 or as soon as possible thereafter. Earlier start dates can also be discussed. For eligible students, the studentship will cover UK/EU/International tuition fees plus an annual tax-free stipend of at least £15,009 for 3.5 years full-time, or pro rata for part-time study. The studentship will be awarded on the basis of merit and will be based in the Dept. of Physics and Astronomy at the College of Engineering, Mathematics and Physical Sciences at the Streatham Campus in Exeter.
Project Description: Models for nanoscale thermal machines have been used for decades to probe the emergence of thermodynamics from quantum theory. Today, these abstract theoretical models are becoming a technological reality with the advent of the first proof-of-principle experiments realising nanoscale (quantum) heat engines and refrigerators. In the near future, it will be feasible to use these systems to cool the nanoscale components of next-generation quantum devices down to ultracold temperatures.
Just like a thermal engineer would do when designing a refrigerator, in this PhD project we will tweak the design of quantum-thermodynamic cooling cycles to attain the best possible compromise between energy-efficiency and cooling load. To do so, we will develop new tools to treat open quantum systems undergoing strong or non-linear dissipation at extreme temperatures. We will also apply this toolbox to improve current precision standards in low-temperature thermometry.
This award provides annual funding to cover UK/EU/International tuition fees and a tax-free stipend. For students who pay UK/EU/International tuition fees the award will cover the tuition fees in full, plus at least £15,009 per year tax-free stipend. The studentship will be awarded on the basis of merit for 3.5 years of full-time study to commence in October 2020 or as soon as possible thereafter. Earlier start dates can be discussed.
