  These notes partly touch the topic of the talk given by the author at the
XXXVIII Workshop on Geometric Methods in Physics, hold in June-July 2019 in
Bia\l{}owie\.{z}a, Poland. They consist of a short and self-contained
introduction to the isomonodromic approach to quantum cohomology, and
Dubrovin's conjecture. An overview of recent results obtained in joint works
with B. Dubrovin and D. Guzzetti (arXiv:1811.09235), and A. Varchenko
(arXiv:1909.06582) is given.
