Query: Topological pairings in Janus monolayer TaSSe   The Janus monolayer transition metal dichalcogenides[TMDs] MXY[M=Mo,W, etc.
and X,Y=S,Se, etc.] has been synthesized recently, and the Rashba spin
splitting arises in it owing to the breaking of out-of-plane mirror
symmetry[\href{https://journals.aps.org/prb/abstract/10.1103/PhysRevB.97.235404}{Phys.
Rev. B 97, 235404 (2018)}]. Here we study the pairing symmetry of
superconducting Janus monolayer H-TaSSe by solving the linearized gap equation
at the critical temperature $T_c$. We find that the strong Rashba effect in
H-TaSSe could produce topological superconducting states which differs from
that in its parent monolayer H-TaS$_2$ and H-TaSe$_2$. More specifically, at
the chemical potential $\mu>-0.08$eV, we obtain a time-reversal invariant
s+f+p-wave mixed pairing state. This pairing state is full-gap and
topologically nontrivial, i.e. $\mathbb{Z}_2=1$. However, a time-reversal
broken d+p+f pairing belonging to the 2-dimensional irreducible representation
$E$ appears at lower chemical potential. It can host a large Chern number
$C=-6$ at appropriate pairing strengths. The results suggest the monolayer
H-TaSSe to be a candidate helical or chiral topological superconductor.
