Robust Nodal Behavior in the Thermal Conductivity of Superconducting UTe2

April 25, 2025
Author(s)
Ian Hayes, Tristin E. Metz, Corey Frank, Shanta R. Saha, Nicholas Butch, Vivek Mishra, P. Hirschfeld, Johnpierre Paglione
The superconducting state of the heavy-fermion metal UTe2 has attracted considerable interest because of evidence of spin-triplet Cooper pairing and nontrivial topology. Progress on these questions requires identifying the presence or absence of nodes in

Connection between f-electron correlations and magnetic excitations in UTe2

January 4, 2025
Author(s)
Thomas Halloran, Peter Czajka, Gicela Saucedo Salas, Corey Frank, Jose Rodriguez Rivera, Daniel Mazzonne, Jakob Lass, Nicholas Butch
Abstract The detailed anisotropic dispersion of the low-temperature, low-energy magnetic excitations of the candidate spin-triplet superconductor UTe 2 is revealed using inelastic neutron scattering. The magnetic excitations emerge from the Brillouin zone

Field-Angle Evolution of the Superconducting and Magnetic Phases of UTe2 around the b Axis

November 27, 2024
Author(s)
Sylvia Lewin, Josephine Yu, Corey Frank, David Graf, Patrick Chen, Sheng Ran, Yun Eo, Johnpierre Paglione, S. Raghu, Nicholas Butch
We experimentally determine the bounds of the magnetic-field-induced superconducting and magnetic phases near the crystalline b axis of uranium ditelluride (UTe2). By measuring the magnetoresistance as a function of rotation angle and field strength in

Inhomogeneous High Temperature Melting and Decoupling of Charge Denisty Waves in Spin-Triplet Superconductor UTe2

May 25, 2024
Author(s)
Alexander LaFleur, Hong Li, Corey Frank, Muxian Xu, Siyu Cheng, Ziqiang Wang, Nicholas Butch, Ilija Zeljkovic
Charge, spin and Cooper-pair density waves have now been widely detected in exotic superconductors. Understanding how these density waves emerge — and become suppressed by external parameters—is a key research direction in condensedmatter physics. Here we

Orphan high field superconductivity in non-superconducting uranium ditelluride.

April 20, 2024
Author(s)
Corey Frank, Sylvia Lewin, Gicela Saucedo Salas, Peter Czajka, Ian Hayes, Hyeok Yoon, Tristin Metz, Johnpierre Paglione, John Singleton, Nicholas Butch
Reentrant superconductivity is an uncommon phenomenon in which the destructive effects of magnetic field on superconductivity are mitigated, allowing a zero-resistance state to survive under conditions that would otherwise destroy it. Typically, the

A Review of UTe2 at High Magnetic Fields

November 1, 2023
Author(s)
Sylvia Lewin, Corey Frank, Sheng Ran, Johnpierre Paglione, Nicholas Butch
ranium ditelluride (UTe2) is recognized as a host material to unconventional spin-triplet superconductivity, but it also exhibits a wealth of additional unusual behavior at high magnetic fields. One of the most prominent signatures of the unconventional
