Research Interests
Physical mechanisms of strong-field quantum control in complex systems: control of femtosecond laser filamentation and nonlinear optics of filament wake channels; spectral control of coherent broadband light generated via dynamic Rabi cycling; strong-field control of electronic and nuclear dynamics in molecules and molecular ions; dimensionality reduction in multi-parameter control and detection spaces; femtosecond four-wave mixing in spatially inhomogeneous systems.
Light scattering in turbid media as applied to noninvasive blood characterization.
Dispersion law engineering and dynamics of quasiparticles with engineered dispersion: mechanics of particles with W-type dispersion; edge magnetic states in systems with non-monotonic potential profile; electronic and optoelectronic properties of fullerene nanotubes; spin-orbit manipulation in quantum wires and in quantum wells with curved geometry.
Electronic and optical properties of nanostructures based on novel materials: electron localization in polarization pockets in thin films of nitride semiconductors; bow-tie optical phonon modes in quantum dots of non-cubic semiconductors; cascade phonon transformations and energy dissipation in quantum wells; novel materials for photodetectors and solar cells.
