The authors show that a GGA+U calculation with U above 1 eV turns insulating DFT UTe2 metallic, and the resulting Fermi surfaces imply time-reversal-invariant topological superconductivity with Majorana surface states for all four odd-parity pairing channels.

Insulator-metal transition and topological superconductivity in UTe2 from a first-principles calculation
The authors show that a GGA+U calculation with U above 1 eV turns insulating DFT UTe2 metallic, and the resulting Fermi surfaces imply time-reversal-invariant topological superconductivity with Majorana surface states for all four odd-parity pairing channels.
