Field-direction sensitivity of Kondo hybridization in UTe $_{2}$

Thomas Halloran, Gicela Saucedo Salas, Sylvia K. Lewin +6

Neutron scattering experiments on the spin-triplet superconductor UTe $_{2}$ have established that the dominant low-energy magnetic response is along Brillouin zone boundaries, resemb…

Limited coincidence between ultrahigh-field superconductivity and line of metamagnetic endpoints in UTe $_{2}$

Peter Czajka, Sylvia K. Lewin, Thomas Halloran +6

The field-dependent magnetization of UTe $_{2}$ was measured through the metamagnetic transition at a variety of field angles, tracking how the step in magnetization evolves with fiel…

Giant transverse magnetic fluctuations at the edge of re-entrant superconductivity in UTe $_{2}$

Valeska Zambra, Amit Nathwani, Muhammad Nauman +6

UTe $_{2}$ exhibits the remarkable phenomenon of re-entrant superconductivity, whereby the zero-resistance state reappears above 40 tesla after being suppressed with a field of arou…

High-Field Superconducting Halo in UTe $_{2}$

Sylvia K. Lewin, Peter Czajka, Corey E. Frank +7

Heavy fermion UTe $_{2}$ is a promising candidate for topological superconductivity that also exhibits multiple high-field superconducting phases. The SC $_{FP}$ phase has only be…

Field-angle evolution of the superconducting and magnetic phases of UTe $_{2}$ around the $b$ axis

Sylvia K. Lewin, Josephine J. Yu, Corey E. Frank +7

We experimentally determine the bounds of the magnetic-field-induced superconducting and magnetic phases near the crystalline $b$ axis of uranium ditelluride (UTe $_{2}$ ). By measurin…
