Due to the large number of posts recently, there is currently a delay of several weeks between posts being submitted and the corresponding emails being distributed to all users. Please bear with us while we try to improve this. In the meantime – and until this notice is removed – it would assist us considerably if you could submit only important and/or urgent posts and thus help to reduce the size of the mail queue. Under no circumstances should you resend posts multiple times when you find the emails are not distributed immediately.
In light of the Russian military offensive in Ukraine, we request that announcements relating to events, jobs and other activities associated with institutions supported by the Russian and Belarusian states are not posted to the Psi-k forum.
PhD position on methods for mesoscopic simulatio ... (No replies)
Back to Job listings...
We are inviting applications for a PhD position at the Luxembourg Institute of Science and Technology (LIST) and the University of Luxembourg. The successful candidate will be part of the Ferroics Materials for Transducers group, developing theoretical and simulation-based research under the supervision of Jorge Íñiguez.
The research will focus on nanostructured ferroelectric materials that gather much attention today, with incredible results being regularly published in magazines like Nature and Science. One main reason for this excitement are the novel ferroelectric textures that these compounds display when reduced to nanometric dimensions and subject to suitable elastic and electric boundary conditions. Most remarkably, these include topologically non-trivial states called skyrmions (google it for amazing pictures!) and often present very interesting and potentially useful properties ranging from “voltage amplification” (which could lead to the development of low-power electronics) to tunable high-frequency responses (needed for ultra-broadband communications) or ultra-fast low-voltage ferroelectric switching (to develop next-generation memories and transistors). Hence, nanostructured ferroelectrics are one of today’s most exciting fields for both research in fundamental physics and the potential development of disruptive technologies.
Theoretical and simulation methods have been critical to advance our understanding and control of these fascinating materials, but we are already exhausting the possibilities of the existing tools. On one hand, atomistic methods do not allow us to access the mesoscopic length and time scales that are relevant to some of the most interesting properties (e.g., skyrmion manipulation). On the other hand, continuum field theories employ models that are too rough to capture the atomistic complexities of these nanostructures and, thus, do not allow us to run truly predictive simulations.
The main goal of this project is to develop continuum methods that retain the accuracy and predictive power of atomistic simulations while allowing us to tackle the relevant mesoscales of interest. The PhD student will benefit from the atomistic-simulation tools and expertise gathered in Jorge Íñiguez’s team at LIST, where many of the seminal ferroelectric skyrmion studies were performed. The new continuum methods will be applied to investigate selected exciting problems, most likely in connection with the dynamical response of complex ferroelectric states.
Our ideal candidates for this PhD:
The position is for 4 years and the starting date is September 1, 2022. We offer a competitive salary and a dynamic work environment in one of the most rapidly-growing and best-funded research ecosystems in Europe.
Interested candidates are welcome to submit their application at this web. Please submit a CV as complete as possible, a full academic record and a letter explaining your interest. For queries, feel free to contact Jorge Íñiguez ([email protected]).
