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…
Conductance of atomic size contacts of Ag and Au at high magnetic fields
Beilun Wu, Andrés MartÃnez, Paula Obladen +6
Electronic conduction at the atomic scale can be described by Landauer's formalism. In single atom point contacts of noble metals like Au and Ag, there is just one channel open bet…
Superconducting density of states and vortex lattice of LaRuP observed by Scanning Tunneling Spectroscopy
Marta Fernández-Lomana, Paula Obladen Aguilera, Beilun Wu +3
We provide the superconducting density of states of the iron based superconductor LaRu2P2 (Tc= 4.1 K), measured using millikelvin Scanning Tunneling Microscopy. From the tunneling…
Gapless superconductivity from extremely dilute magnetic disorder in 2H-NbSe2-xSx
Jose Antonio Moreno, Mercè Roig, VÃctor Barrena +14
Most superconducting materials exhibit a vanishing density of states at the Fermi level and Anderson's theorem posits that the superconducting gap is robust against nonmagnetic dis…
The feedback driven atomic scale Josephson microscope
Samuel D. Escribano, VÃctor Barrena, David Perconte +10
The ultimate spatial limit to establish a Josephson coupling between two superconducting electrodes is an atomic-scale junction. The Josephson effect in such ultrasmall junctions h…
