Boosted magnetic fluctuations at the onset of superconductivity in UTe beyond 40 T
T. Thebault, K. Somesh, G. Lapertot +11
Several unconventional superconducting phases have been discovered close to a metamagnetic transition in the heavy-fermion compound UTe. Although suspected to be of magnetic na…
Fermi-liquid versus non-Fermi-liquid/'strange-metal' fits to the electrical resistivity in the quantum critical magnetic regime of an unconventional superconductor
W. Knafo, T. Thebault, K. Somesh +4
The question of a possible quantum critical point lying inside of a superconducting phase is central for understanding unconventional superconductivity. In various unconventional s…
Quantitative thermodynamic study of superconducting and normal states in UTe2 under pressure
T. Vasina, M. Pfeiffer, R. Borth +7
We report a quantitative calorimetric study of UTe2 under pressure with a direct measurement of the Sommerfeld gamma coefficient, showing a three-fold enhancement of electronic eff…
Surface charge density wave in UTe2
Pablo GarcÃa Talavera, Pablo García Talavera, Miguel Ãgueda Velasco +16
The spatially uniform electronic density characteristic of a metal can become unstable at low temperatures, leading to the formation of charge density waves (CDWs). These CDWs, obs…
Bulk signatures of re-entrant superconductivity in UTe from ultrasound measurements
N. Marquardt, C. Duffy, C. Proust +7
We report bulk ultrasound measurements up to 80 T and down to 0.5 K of the field re-entrant superconducting phase of the unconventional superconductor UTe. Clear bulk signature…
Incommensurate and commensurate antiferromagnetic orders in the kagome compound UVSn
Midori Amano Patino, Stephane Raymond, Georg Knebel +12
We report on the synthesis of single crystals of the kagome compound, UVSn, and present the results of magnetization, electrical resistivity, heat capacity, x-ray, and neut…
