Query: Periodic Anderson model for magnetism and superconductivity in UTe2   We provide and analyze a periodic Anderson model for studying magnetism and
superconductivity in UTe$_2$, a recently-discovered candidate for a topological
spin-triplet superconductor. The 24-band tight-binding model reproduces the
band structure obtained from a DFT$+U$ calculation consistent with an
angle-resolved photoemission spectroscopy. The Coulomb interaction of
$f$-electrons enhances Ising ferromagnetic fluctuation along the $a$-axis and
stabilizes spin-triplet superconductivity of either $B_{3u}$ or $A_{u}$
symmetry. When effects of pressure are taken into account in hopping integrals,
the magnetic fluctuation changes to antiferromagnetic one, and accordingly
spin-singlet superconductivity of $A_{g}$ symmetry is stabilized. Based on the
results, we propose pressure-temperature and magnetic field-temperature phase
diagrams revealing multiple superconducting phases as well as an
antiferromagnetic phase. In particular, a mixed-parity superconducting state
with spontaneous inversion symmetry breaking is predicted.
