We establish the duality between the torus knot superpolynomials or the
Poincar\'e polynomials of the Khovanov homology and particular condensates in
Ω-deformed 5D supersymmetric QED compactified on a circle with 5d
Chern-Simons(CS) term. It is explicitly shown that n-instanton contribution
to the condensate of the massless flavor in the background of four-observable,
exactly coincides with the superpolynomial of the T(n,nk+1) torus knot where
k - is the level of CS term. In contrast to the previously known results, the
particular torus knot corresponds not to the partition function of the gauge
theory but to the particular instanton contribution and summation over the
knots has to be performed in order to obtain the complete answer. The
instantons are sitting almost at the top of each other and the physics of the
"fat point" where the UV degrees of freedom are slaved with point-like
instantons turns out to be quite rich. Also also see knot polynomials in the
quantum mechanics on the instanton moduli space. We consider the different
limits of this correspondence focusing at their physical interpretation and
compare the algebraic structures at the both sides of the correspondence. Using
the AGT correspondence, we establish a connection between superpolynomials for
unknots and q-deformed DOZZ factors.Comment: v2: text substantially improve
