Flat-band (FB) photonic lattices have been in the focus of researchers since they represent an excellent
platform for studying various fundamental physical phenomena difficult to achieve in the condensed
matter systems. Working with photonic lattices is very comfortable because they are easy to manipulate with
and it is possible to directly observe the wave dynamics. An important property of FBs lattice is that they can
host a complete set of compact localized modes (CLMs), highly robust to environmental noise. Due to lattice
their geometry, it is possible to design artificial gauge field effects which are equivalent to the magnetic field
flux, i. e. the spin-orbit interaction in atomic systems.
We have studied a two-dimensional (2D) linear and nonlinearphotonic lattices dressed by the artificial flux and
have explored the influence of the artificial gauge field on the energy band spectrum. We investigated CLM
in three types of 2D photonic lattices: octagonal-diamond, dice and... plus-like lattice. Each of these lattices is
characterized by the presence of diamond plaquettes in the structure. When diamond plaquettes are dressed by
artificial flux, the Aharonov-Bohm effect has caused the appearance of new FBs for certain values of the flux.
The dynamics of the CLMs in the mentioned flux-dressed lattices have been analyzed numerically, using
the Runge-Kutta procedure of the 6th order. To describe the dynamic properties of CLMs, in the presence
of nonlinearity and artificial flux, we calculated some of the following quantities: the participation number,
which is a measure of the mode localization; the mode overlapping, which represents normalized magnitude
of the field overlap; and total intensity distribution. The evolution of these quantities show the efficiency of the
mode compactness andlocalization.
