Multiple Superconducting Phases under Pressure for Different Field Directions in UTe2
Dai Aoki, Atsushi Miyake, Ai Nakamura +7
The existence of multiple superconducting phases is a striking feature of UTe2, arising from the spin and orbital degrees of freedom and supporting a spin-triplet superconducting s…
Successive Electronic Topological Transitions in the Antiferromagnet UPdAl
Adrien Gourgout, Gaël Bastien, Dai Aoki +7
We report successive anomalies at low temperature in the magnetic field dependence of the thermoelectric signal in the heavy fermion compound UPdAl inside the antiferro…
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…
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…
(p,T,H) phase diagram of Heavy Fermion systems : Some systematics and some surprises from ytterbium
D. Braithwaite, A. Fernandez-Pañella, E. Colombier +8
Pressure is the cleanest way to tune heavy fermion systems to a quantum phase transition in order to study the rich physics and competing phases, and the comparison between ytterbi…
Tunneling spectroscopy of the superconducting state of URu2Si2
A. Maldonado, I. Guillamon, J. G. Rodrigo +4
We present measurements of the superconducting gap of URuSi made with scanning tunneling microscopy (STM) using a superconducting tip of Al. We find tunneling conductance c…
Convergence of the enhancement of the effective mass under pressure and magnetic field in heavy-fermion compounds: CeRu2Si2, CeRh2Si2, and CeIn3
J. Flouquet, D. Aoki, W. Knafo +6
Emphasis is given on the observation of a convergence to a critical value of the effective mass of a heavy fermion compound by tuning it through a quantum instability either by app…
Inelastic neutron scattering study of single crystal heavy fermion YbAgGe
B. Fak, D. F. McMorrow, P. G. Niklowitz +7
Single crystals of the heavy-fermion compound YbAgGe have been studied by neutron scattering. The magnetic ordering occurring below T1=0.5 K is characterized by a commensurate prop…
Thermal Conductivity and Gap Structure of the Superconducting Phases of UPt3
H. Suderow, J. P. Brison, A. Huxley +1
We present new measurements of the thermal conductivity of UPt3 down to very low temperatures (16mK) and under magnetic fields (up to 4 T) which cover all the superconducting phase…
