Restoration of superconductivity in high magnetic fields in UTe2

It was theoretically predicted more that 20 years ago [see A.G. Lebed and K. Yamaji, Phys. Rev. Lett., v. 80, 2697 (1998)] that a
triplet quasi-two-dimensional (Q2D) superconductor could restore its superconducting state in parallel magnetic fields, which are
higher than its upper critical magnetic field, H > Hc2. It is very likely that recently such phenomenon has been
experimentally discovered in the Q2D superconductor UTe2 by Nicholas Butch, Shen Ran and their colleagues and confirmed by
Japanese-French team. We improve our previous theoretical results using such a general formalism that it explains the concrete situation
with the reentrant superconductivity in the above mentioned compound as well as will hopefully cover similar phenomena, which
can be discovered in other Q2D superconductors.
