Particle dynamics in optical lattices

We present a thorough experimental and theoretical study of micrometer-sized particle dynamics in optical lattices. The spatial parameters of the lattices are set by configuration of the interfering beams with computercontr...

Static particle sorting in 1D optical lattice

We demonstrate how the simple one-dimensional optical lattices can be used to sort micron-sized particles. Experimentally we focused on the simplest case where the periodical structure is created by an interference of two co-propaga...

Elasto-optic behaviour in epitaxial films of perovskite oxide ferroelectrics

to the lattice strain in the films. Elasto-optic coefficient is formally estimated using the out-of-plane lattice elongation or shrinkage in the films compared to bulk in epitaxial perovskite oxide ferroelectric films expe...

Contributions from coherent and incoherent lattice excitations to ultrafast optical control of magnetic anisotropy of metallic films

Spin-lattice coupling is one of the most prominent interactions mediating response of spin ensemble to ultrafast optical excitation. Here we exploit optically to picosecond lattice temperature raise, give raise to ...
