Head of Laboratory: Wojciech GADOMSKI
Staff at Professors Positions: Wojciech Gadomski
Staff with Ph.D. Degree: Wojciech Gadomski, Bożena Gadomska, Ewa Górecka, Bożena Janowska-Dmoch, Adam Krówczyński, Marek Pękała, Damian Pociecha, Jadwiga Szydłowska, Krzysztof Twarowski, Krzysztof Zboiński

Number of Ph.D. Students: 1

Areas of Scientific Activity:
Ordered, partly-ordered and disordered systems: the molecular dynamics, structures, the phase properties, the linear and nonlinear interactions with laser light; femtosecond phenomena in dense matter; liquid crystals, gels, molecular liquids, nanocrystaline structures.
1. Synthesis of mesogens with non-conventional molecular structure - compounds with hydrogen bonded quasi rings, metallorganic cores and chiral flexible joints. Experimental methods: calorimetry, polarizing microscopy, EPR and X-ray diffraction.
2. Nonlinear, laser-induced femtosecond molecular dynamics in liquids and crystals - theoretical and experimental approach. Chaos and dynamic instabilities during the interaction of light with the crystal lattice. Self-organization processes in time-resolved fluorescence and Raman spectroscopy: sol-gel transitions. Nonlinear laser dynamics: chaos and optical instabilities.
3. The studies of nanocrystalline alloys and high temperature superconductors: magnetic and electron transport phenomena, thermal conductivity, magnetostriction and thermoelectric power, anisotropy of the Nernst effect.
