Welcome to AMRELAT LABORATORY located in the Department of Physics of School of Sciences & Humanities of Nazarbayev University!

 

We advance the science of heat, sound and mechanics at nano- and micro-scales through advanced laser-based diagnostics and optical spectroscopies. We reveal how defects, radiation, interfaces and microstructure govern phonon-mediated thermal and elastic behavior in advanced materials, enabling predictive control of energy transport under extreme and technologically relevant conditions. Our research integrates laser-based material science, optical sensing, structural characterization and multi-scale modeling with the focus on: (1) nano- and micro-scale thermal transport in ion-irradiated, nanostructured, interfacial and phase-transformed materials investigated using advanced femtosecond and continuum laser-based thermoreflectance & opto-thermal Raman spectroscopy measurements and atomistic simulations, (2) spatially-resolved elastic and visco-elastic properties of irradiated solids and soft matter probed non-destructively by Brillouin light scattering spectroscopy at GHz frequencies and (3) high-temperature thermo-physics and laser-driven phase transitions explored through nanosecond laser acoustics and molecular dynamics simulations of melting and energy dissipation. By bridging fundamental phonon physics with advanced optical metrology, we deliver new insights into thermal transport, radiation tolerance and mechanical resonse in materials deisgned for energy, extreme environments and next-generation technologies.
