from angle resolved photoemission spectroscopy*

The compound UTe₂ has recently been shown to realize spin triplet superconductivity from a non-magnetic normal state. This has sparked intense research activity, including theoretical analyses that suggest the superconducting order parameter to be topologically nontrivial. However, the underlying electronic band structure is a critical factor for these analyses, and remains poorly understood. I will present high resolution angle resolved photoemission (ARPES) measurements covering multiple planes in the 3D Brillouin zone of UTe₂, revealing distinct Fermi pockets from two light electron bands and one heavy band. Electronic symmetries and many-body ordering instabilities will be discussed in comparison with numerical simulations.
