Query: Floquet topological $d+id$ superconductivity induced by chiral many-body
  interactions   We study how a $d$-wave superconductivity is changed when illuminated by
circularly-polarised light (CPL) in the repulsive Hubbard model in the
strong-coupling regime. We adopt the Floquet formalism for the
Gutzwiller-projected effective Hamiltonian with the time-periodic
Schrieffer-Wolff transformation. We find that CPL induces a topological
superconductivity with a $d+id$ pairing, which arises from the chiral spin
coupling and the three-site term generated by the CPL. The latter term remains
significant even for low frequencies and low intensities of the CPL. This is
clearly reflected in the obtained phase diagram against the laser intensity and
temperature for various frequencies red-detuned from the Hubbard $U$, with the
transient dynamics also examined. The phenomenon revealed here can open a
novel, dynamical way to induce a topological superconductivity.
