Quantum Jacobi forms were defined in 2016, naturally combining Zagier’s definition of a quantum modular form with that of a Jacobi form. To date, just three examples of such functions exist in the literature. Here, we prove that the universal mock theta function $$g_2$$g2, as well as the universal mock theta functions $$K, K_1, K_2,$$K,K1,K2, and $$\kappa $$κ, gives rise to an infinite family of quantum Jacobi forms $$G_{a,b}(z;\tau )$$Ga,b(z;τ) of weight 1 / 2 in dense subsets $${{\mathscr {Q}}}_{a,b} \subseteq {\mathbb {Q}} \times {\mathbb {Q}}$$Qa,b⊆Q×Q. We then use these quantum Jacobi transformation properties to establish polynomial expressions for $$G_{a,b}$$Ga,b at pairs of rational numbers, as well as simple closed-form expressions for sums of Mordell integrals.
