Professor IF PAN Marcin Matusiak

I am a physicist interested in the properties of electronic matter manifested in electrical and thermal transport phenomena. I graduated in 1997 from the Wroclaw University of Science and Technology and begun my scientific journey at the Institute of Low Temperature and Structure Research (ILT&SR), Polish Academy of Sciences in Wroclaw.  There, I obtained in 2002 a doctoral degree under supervision of prof. Jan Klamut and dr hab. Tomasz Plackowski. At that time I became interested in normal state properties of high-Tc superconductors [Normal-state Ettingshausen, Seebeck, and Hall effects in La2−xSrxCuO4] that grew into a leading theme of my research for quite a long time. The first exception was a one-year (2002-2003) visit at the University of Florida, Gainesville, FL, U.S.A, when I was involved in the study of relaxation processes for small grains of solid hydrogen suspended in liquid helium. This project was a part of a NASA – funded grant led by prof. Neil Sullivan and prof. Gary G. Ihas. A destination of my next long term scientific visit (2006-2008) was the University of Cambridge, U.K., where under supervision of prof. John R. Cooper I again studied transport properties of the high-Tc superconductors. This research was mostly focused on measurements of the thermoelectrical phenomena [Nernst Effect Measurements of Epitaxial Y0.95Ca0.05Ba2(Cu1‑xZnx)3Oy and Y0.9Ca0.1Ba2Cu3Oy Superconducting Films] but we were also interested in quantum oscillations that were very recently discovered in high-Tc superconductors [Fermi surface and electronic homogeneity of the overdoped cuprate superconductor Tl2Ba2CuO6+δ as revealed by quantum oscillations]. After returning to ILT&SR, I turned my attention to iron-based superconductors  [Nernst effect in single crystals of the pnictide superconductor CaFe1.92Co0.08As2 and parent compound CaFe2As2], which resulted in the award of three consecutive research grants [Thermomagnetic transport phenomena in strongly correlated electron systems (2010-2013), Pseudogap in the iron based superconductors (2012-2016),  Studies of the nematic phase in the iron based superconductors (2015-2020)]. In the meantime, I obtained my habilitation (2013) and spent one year in prof. Luis Taillefer’s laboratory at the Université de Sherbrooke, Quebec, Canada (2013-2014). This visit brought me back to the subject of high-Tc superconductors [Pseudogap phase of cuprate superconductors confined by Fermi surface topology] but then I gradually started to shift toward studies of topologically non-trivial materials [Thermoelectric quantum oscillations in ZrSiS]. Eventually, this interest caused me to join MagTop in 2020, where together with my collaborators we investigate the thermoelectrical [Sign change of anomalous Hall effect and anomalous Nernst effect in the Weyl semimetal CeAlSi] and thermal [Severe violation of the Wiedemann-Franz law in quantum oscillations of NbP] properties of topological semimetals.
