Query: Effective Hamiltonian with tunable mixed pairing in driven optical
  lattices   Mixed pairing in ultracold Fermi gases can give rise to interesting many-body
phases, such as topological nontrivial superfluids that support Majorana zero
modes (MZMs) with various spatial configurations. Unfortunately, in ordinary
lattice systems, the topological phase and the associated MZMs are suppressed
by the dominant $s$-wave pairing. Here we present a proposal for engineering
effective Hamiltonians with tunable mixed on- and off-site pairing based on
driven optical lattices. The on- and off-site pairing can be changed
independently by means of a periodical driving field rather than magnetic
Feshbach resonances. It paves the way for suppressing the dominant on-site
interaction that frustrates the emergence of topological superfluids and for
synthesizing MZMs localized in edges or corners.
