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…
Bridging atomic and mesoscopic length scales with Replica Scanning Tunneling Microscopy: Visualizing the atomic lattice of UTe and the atomic scale superconducting gap modulations of FeSe close to micron length scales
Miguel Águeda Velasco, Jose D. Bermúdez-Pérez, Pablo García Talavera +16
Scanning Tunneling Microscopy is a cornerstone technique for visualizing the electronic density of states with atomic resolution (typically below 0.1 nm). While the field of view o…
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…
Anisotropic collapse of electronic correlations in the ferromagnet UGe under high magnetic field
K. Somesh, T. Thebault, V. Taufour +5
We present electrical-resistivity measurements on the prototypical heavy-fermion ferromagnet UGe under pulsed magnetic field up to 60~T. An anisotropic field-induced suppressio…
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…
Discovery of a new phase in thin flakes of KVSb under pressure
Zheyu Wang, Lingfei Wang, King Yau Yip +13
We report results of magnetotransport measurements on KVSb thin flakes under pressure. Our zero-field electrical resistance reveals an additional anomaly emerging under pre…
Connecting High-Field and High-Pressure Superconductivity in UTe2
T. Vasina, D. Aoki, A. Miyake +9
The existence of multiple superconducting phases induced by either pressure or magnetic field is one of the most striking features of superconductivity of UTe, among the many u…
Large Fermi surface in pristine kagome metal CsVSb and enhanced quasiparticle effective masses
Wei Zhang, Tsz Fung Poon, Chun Wai Tsang +11
The kagome metal CsVSb is an ideal platform to study the interplay between topology and electron correlation. To understand the fermiology of CsVSb, intensive quant…
