PhD position in nonlinear laser spectroscopy on novel types of ferroic order

PhD position in nonlinear laser spectroscopy on novel types of ferroic order
—————————————————————————-
In the Laboratory for Functional Ferroic Materials we investigate materials where strong coupling between electrons leads to novel types of ordering processes of their spins and charges. We study the fundamental physics of these materials with a focus on experimental basic research yet including the perspectives on theoretical background and technological relevance. Our experimental core technologies are nonlinear and ultrafast optical spectroscopy with pulsed lasers. In addition, we apply scanning probe microscopy, standard magnetic and dielectric characterization methods, Monte-Carlo simulation, and pulsed-​laser-deposition of oxide thin films.

Project background
——————
The PhD project unites our leading international expertise in nonlinear laser spectroscopy and (multi-) ferroic materials. Currently the possible existence and physical properties of new forms of ordered states in matter are intensively discussed. Examples are advanced multiferroicity, altermagnetism, hidden order, chiral states, or topological phases. Systematic exploration of such states is an emerging topic and therefore offers the opportunity to contribute to the development of a new research field.

Job description
—————
The goal of the doctoral project is to explore such novel manifestations of ferroic order with the use of pulsed-laser systems. The distribution and manipulation of the ordered regions – domains – exhibited by such novel ferroics is of particular interest because domains reveal the coupling processes underlying the ordered state and are also key to device functionality.

There are not many labs in the world with the knowledge to do this kind of work, and so studies of domains in new types of ferroic materials are scarce despite their significance for basic and applied research. To the curious person, the PhD project thus offers plenty of room for exciting physics and groundbreaking discoveries, and our lab has exactly the expertise to acquire these.

Candidates will use our workplaces for nonlinear laser spectroscopy. They will design and set up their own experiment and are never afraid to tear it down and try a new approach, should this become necessary. Candidates will also learn to work with cryogenic environments. Despite the focus on laser-based experiments, the involvement of other experimental techniques and in-depth discussion with theoretical groups are likely.
