Pseudo Point Nodal Superconducting Gap in Spin-Triplet UTe
S. Hosoi, K. Imamura, M. M. Bordelon +7
The unconventional superconductor UTe represents a rare example of spin-triplet pairing with potentially topologically protected quantum states. However, conflicting reports on…
Random singlet physics in exchange disordered 2D triangular YbCuSe
Caitlin S. T. Kengle, Sean M. Thomas, Roman Movshovich +5
Quantum spin liquid (QSL) phases exist in theory, but real candidate QSL materials are often extraordinarily sensitive to structural defects which disrupt the ground state. Here, w…
Tracking flat bands via phonon-mediated interband scattering
Fabian Garmroudi, Jennifer Coulter, Xinlin Yan +7
Flat-band (FB) systems offer a fertile platform for realizing exotic correlated and topological phases, yet central challenges remain in tuning FBs towards the Fermi level $E_\text…
Hydrostatic pressure studies on non-superconducting UTe2
M. O. Ajeesh, Joe D. Thompson, Eric D. Bauer +3
We report the temperature-pressure phase diagram of a UTe single crystal that does not undergo a bulk superconducting transition but shows filamentary superconductivity with a…
Observation of Persistent Zero Modes and Superconducting Vortex Doublets in UTe
Nileema Sharma, Matthew Toole, James McKenzie +5
Superconducting vortices can reveal electron pairing details and nucleate topologically protected states. Yet, vortices of bulk spin-triplet superconductors have never been visuali…
Realizing a topological diode effect on the surface of a topological Kondo insulator
Jiawen Zhang, Zhenqi Hua, Chengwei Wang +10
Introducing the concept of topology into material science has sparked a revolution from classic electronic and optoelectronic devices to topological quantum devices. The latter has…
Coexistence of Kondo Coherence and Localized Magnetic Moments in the Normal State of Molten Salt-Flux Grown UTe2
N. Azari, M. Yakovlev, S. R. Dunsiger +9
The development of Kondo lattice coherence in UTe2 leads to the formation of a heavy Fermi liquid state from which superconductivity emerges at lower temperature. In Kondo lattice…
Absence of Spontaneous Magnetic Fields Due to Time-Reversal Symmetry Breaking in Bulk Superconducting UTe2
N. Azari, M. Yakovlev, N. Rye +7
We have investigated the low-temperature local magnetic properties in the bulk of molten salt-flux (MSF) grown single crystals of the candidate odd-parity superconductor UTe2 by ze…
The fate of time-reversal symmetry breaking in UTe2
M. O. Ajeesh, M. Bordelon, C. Girod +7
Topological superconductivity is a long-sought state of matter in bulk materials, and odd-parity superconductor UTe is a prime candidate. The recent observation of a field-trai…
Single-component superconducting state in UTe2 at 2 K
P. F. S. Rosa, A. Weiland, S. S. Fender +5
UTe2 is a newly-discovered unconventional superconductor wherein multicomponent topological superconductivity is anticipated based on the presence of two superconducting transition…
Spatially inhomogeneous superconductivity in UTe2
S. M. Thomas, C. Stevens, F. B. Santos +6
Newly-discovered superconductor UTe is a strong contender for a topological spin-triplet state wherein a multi-component order parameter arises from two nearly-degenerate super…

K. E. Avers, P. A. Maksimov, P. F. S. Rosa +5
CeCdAs is a rare-earth triangular-lattice antiferromagnet with large inter-layer separation. Our field-dependent heat capacity measurements at dilution fridge temperatures…
Quantum critical scaling in the disordered itinerant ferromagnet UCoFeGe
K. Huang, S. Eley, P. F. S. Rosa +5
Belitz-Kirkpatrick-Vojta (BKV) theory shows in excellent agreement with experiment that ferromagnetic quantum phase transitions (QPTs) in clean metals are generally first-order due…
