Clemens Ulrich

Associate Professor

A/Prof. Clemens Ulrich started his scientific research with Raman Light Scattering in semiconductors under high hydrostatic pressure in 1994 at the Max-Planck institute for solid state research in Stuttgart, where he performed his PhD thesis in the group of M. Cardona. In 1999 C. Ulrich joined the Bell Laboratories/Lucent Technologies and NIST (the National Institute od Standards and Technology) in the USA as postdoctoral research fellow. 

The main topics of his research in the last 10 years were strongly correlated electron systems like unconventional superconductors or transition metal oxides. Of special interest were the effects of spin, charge, and orbital correlations in 3-dimensional perovskite systems with partly occupied 3d-electronic levels. The used experimental techniques were inelastic neutron scattering, Raman lights scattering, and resonant inelastic x-ray scattering (ESRF/Grenoble and PSI/Switzerland). The combination of these complementary techniques allowed to yield a detailed insight in the physics behind strongly correlated electron systems.

Clemens Ulrich was the group leader of the Raman laboratories at the Max-Planck Institute in Stuttgart. He was involved in inelastic neutron scattering experiments (triple-axis-spectrometers and time-of-flight spectrometers) and has performed resonant inelastic x-ray scattering experiments at various synchrotron facilities in Europe.

Clemens Ulrich has more than 60 refereed publications in high-impact journals in magnetism, strongly correlated electron materials and condensed matter physics. His publications were cited more than 1350 times and his Hirsch index is 19.

A/Prof. C. Ulrich joined University of New South Wales in April 2009 in a joint position with ANSTO/The Bragg Institute in Sydney. His main fields of research are strongly correlated electron systems, such as novel superconductors or multiferroic materials. His experimental techniques are neutron scattering at the OPAL research reactor at ANSTO and Raman light scattering at the newly establiched optical laboratories at the UNSW in Sydney.

Project: ”SOPRANO - Spin and Orbital Physics: Research of Advanced New Oxides",
A/Prof. C. Ulrich was the project coordinator at the Max-Planck Institute in Stuttgart, Germany (Group of Prof. B. Keimer). His part of the project was awarded 600,000 Euro for a period of 5 years for PhD students and post doctoral fellows. The entire grant is in total worth 4.65 Million Euro, distributed over five participating institutes and universities.

The philosophy of my research is to combine different complementary techniques in solid state spectroscopy such as optical spectroscopy, neutron scattering, and advanced X-ray synchrotron techniques, in order to obtain a comprehensive understanding of fundamental processes in particular in transition metal oxides such as spin, charge, and orbital correlations. Materials investigated encompass both, single crystals and powder samples as well as thin film samples.

Keywords: Strongly correlated electron systems, unconventional superconductors or transition metal oxides, effects of spin, charge, and orbital correlations in 3-dimensional perovskite systems with partly occupied 3d-electronic levels.
