Postdoc Cfm-souza

**AND OPTICAL PHENOMENA IN BROKEN SYMMETRY MATERIALS”**

**Materials Physics Center (Donostia / San Sebastián)**

The **Souza Group** at CFM is offering a postdoctoral position (1+1 years) starting between
April and the end of June 2023 to work with Prof. Ivo Souza, in collaboration with Dr.
Fernando de Juan and with Dr. Stepan Tsirkin, on first-principles studies of transport and
optical effects sensitive to broken symmetries - such as structural chiraliry and
antiferromagnetic order - that are "invisible" to standard electromagnetic probes. Such
effects include magnetoelectric and quadrupolar couplings, natural optical activity,
directional dichroism, and nonlinear (magneto)transport.

The positions will be funded by MCIN and by the European Union NextGenerationEU/PRTR
- C17.I1, as well as by IKUR Strategy under the collaboration agreement between Ikerbasque
Foundation and DIPC on behalf of the Department of Education of the Basque Government.

Center. The salary will be of 35.650,44 euros during the first year before taxes.

The Souza Group at the Center of Materials Physics uses theoretical and computational
tools to study the properties of materials from first principles. Our work involves the
materials that are being studied experimentally. Current research topics in the group include
the study of nonlinear optical and transport phenomena arising in crystals with broken
symmetries from the Berry-phase geometry of the electronic states. For more information,

background in solid state physics is required, as well as experience with density-functional
theory (DFT) calculations and good programming skills. Knowledge of the internals of
community DFT codes is highly desirable.
