Query: Tailoring Metal Insulator Transitions $\&$ Band Topology via
  Off-resonant Periodic Drive in an Interacting Triangular Lattice   A triangular lattice with onsite Coulomb interaction $U$ present only on one
sub-lattice, is periodically driven by electromagnetic field with a frequency
$\Omega \gg (t,~U)$ at half filling. In this high frequency limit, the
electromagnetic vector potential, with an amplitude $A$, modifies the bare
hopping and generates new next nearest neighbour hopping parameters. For $U=0$,
the driving acts like an emergent intrinsic spin-orbit coupling term and
stabilises three dispersive bands with the lower and upper bands having non
zero Chern numbers. Within a slave rotor mean field theory, we show that while
$U$ freezes out charge fluctuations on the interacting sub-lattice, it does not
open up a charge gap without the external drive. In presence of the drive, and
small $U$, the system exhibits repeated metal insulator transitions as a
function of the amplitude $A$. For large $U$, we establish that the freezing of
charge fluctuations on the interacting sub-lattice stabilizes an emergent, low
energy \textit{half filled non-interacting Kane-Mele model}, whose band gaps
can be tuned by varying $A$. In this limit, we show that the external drive
provides an handle to engineer periodic band inversions at specific values of
$A$ accompanied by topological phase transitions that are characterised by
swapping of band Chern numbers.
