Unusual upper critical field in UTe2 revealed by magnetotransport measurements up to 42 T
Macha Méplan, Ilya Sheikin, Pierre Pugnat +16
The heavy-fermion superconductor UTe2 is unique in that, at ambient pressure, it exhibits three distinct superconducting phases, two of which are induced by magnetic field. When th…
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…
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…
Metastability of the Topological Magnetic Orders in the Chiral Antiferromagnet EuPtSi
Simon Rousseau, Gabriel Seyfarth, Georg Knebel +3
We report resistivity and Hall effect measurements in the chiral antiferromagnet EuPtSi. Depending on the magnetic field orientation with respect to the crystallographic axes, EuPt…
Well-posedness of Heat Equations with Nonlinearities of Arbitrarily Rapid Growth
Yohei Fujishima, Kotaro Hisa, Robert Laister
We address local- and global-in-time well-posedness of the Cauchy problem for nonlinear heat equations without imposing growth rate restrictions on the nonlinearity a priori. Our r…
High Field Superconducting Phases of Ultra Clean Single Crystal UTe2
Dai Aoki, Ilya Sheikin, Nils Marquardt +3
We report the magnetoresistance of high-quality single crystals of UTe2 with Tc=2.1K in high magnetic fields up to 36T, with the field direction between the b and c-axes. From the…
