OePG-CMD-Graz2026

75th Annual Meeting of the Austrian Physical Society
32nd Meeting of the Condensed Matter Division of the European Physical Society

20 - 25 September 2026, University of Graz, Graz Center of Physics, Graz, Austria

The OePG-CMD-Graz2026 conference will be held in the premises of the University Graz (Austria) from September 20^th through September 25^th, 2026. OePG-CMD-Graz2026 is an international conference of the Austrian Physical Society (OePG) together with the Condensed Matter Division (CMD) of the European Physical Society. On the OePG side, the conference covers a wide spectrum of physics representing the activities of Austrian physicists including acoustics, condensed matter, energy and sustainability, nuclear and particle physics, space plasma physics, medical physics, biophysics and more.

The CMD covers all aspects of Condensed Matter Physics and Physics of Materials, including soft condensed matter, liquid physics, biophysics, materials science, quantum physics, low temperature physics, strongly correlated materials, semiconductor physics, magnetism, superconductivity, surface and interface physics, electronic, optical, structural, and mechanical properties of materials, acoustics, disordered media, applications of materials, etc. Other related topics such as interdisciplinary topics and the development of research infrastructure in Europe are welcome.

11 Hall coefficient signals orbital differentiation in the Hund’s metal Sr$_2$RuO$_4$

The Hall coefficient $R_H$ of Sr$_2$RuO$_4$ exhibits a non-monotonic temperature dependence with two sign reversals. We show that this puzzling behavior is the signature of two crossovers, which are key to the physics of this material. The increase of RH and the first sign change upon cooling are associated with a crossover into a regime of coherent quasiparticles with strong orbital differentiation of the inelastic scattering rates. The eventual decrease and the second sign change at lower temperature are driven by the crossover from inelastic to impurity-dominated scattering. This qualitative picture is supported by quantitative calculations of $R_H(T)$ using the Boltzmann transport theory in combination with dynamical mean-field theory, taking into account the effect of spin–orbit coupling. Our insights shed new light on the temperature dependence of the Hall coefficient in materials with strong orbital differentiation, as observed in Hund’s metals.
