Main topics

Strongly correlated materials are condensed matter systems, in which the energy of electron-electron interactions are strong and comparable to electron kinetic energy. Strong electronic correlations result in unusually rich and complex physics. The examples of exotic phenomena, which have been discovered in such systems, are high temperature superconductivity in cuprate oxides, and, more recently, in iron-based pnictides and chalkogenides, or the colossal magnetoresistance in manganites.
Competing interactions, involving charge, spin, orbital, and lattice degrees of freedom, produce complex phase diagrams, in which many phases with distinct ground electronic state coexist. These phases usually display different magnetic, electrical or thermal properties. The systems may be tuned between various phases either by doping, or by small variation of external parameters, such as temperature, magnetic field, or pressure. The ability of tuning of the physical properties promises applications of these materials in modern electronics.
The research carried out by our group focuses on two important aspects of material studies: the growth of materials, and the experimental investigation of their physical properties. Some examples of the topics are listed below.
