My research focuses
on the study of correlated systems like transition
metal oxides
on frustrated
lattices by applying various analytical and numerical methods.
It covers
the following
topics:
The study of ground state
properties of frustrated lattices with spin, charge and orbital degrees
of freedom.
The study of magnetic excitation spectrum in systems with unquenched
orbital angular momentum.
The study of
the two-magnon Raman scattering on two-dimensional magnetic frustrated
lattices, such as triangular, kagome stripe, and checkerboard lattices.
The study of
the two-orbiton Raman scattering on frustrated lattices, when the
orbital degrees of freedom plays an important role.
The study of low-dimensional magnetic systems.
Interest in
these systems stems from (i) the
richness of their novel properties: the unexpected variety of ordered
states and transitions between them, (ii) the complexity of the
underlying physics; (iii) the presence of frustration, which makes
these systems
highly sensitive to any internal or external perturbations. Such a
richness of
properties is largely connected with the simultaneous presence of
the geometrical frustration and the strongly correlated effects, which
lead to a
keen interplay of different degrees of freedom in these systems:
charge, spin and orbital ones as well as crystal lattice.
