Visualizing impurity-driven scattering phase textures in EuCd2As2
Raquel Sánchez-Barquilla, Rafael Pineda Medina, Pablo García Talavera +11
Understanding how disorder modifies electronic states in magnetic semiconductors is important for controlling spin-dependent transport and topological responses. Here we use scanni…
Scanning Tunneling Microscopy in high vectorial magnetic fields
Jaime Rumeu Ozores, Miguel Águeda Velasco, Edwin Herrera +10
The Scanning Tunneling Microscope (STM) is a powerful instrument to study electronic density of states at surfaces down to atomic scale. Many interesting samples require studying v…
Scanning tunneling spectroscopy of superconducting nitridized aluminum thin films
Jose Antonio Moreno, Pablo García Talavera, Alba Torras-Coloma +5
Nitride-based superconductors represent a family of superconducting thin film materials displaying higher quality than their corresponding bare superconductor when used in devices…
Direct observation of vortex liquid droplets in the iron pnictide superconductor CaKAsFe at _c$
Oscar Bou Marqués, Jose A. Moreno, Pablo García Talavera +7
Type-II superconductors under magnetic fields are in a quantum coherent non-dissipative state as long as vortices remain pinned. Dissipation appears when vortices depin, eventually…
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…
Robust two-dimensional surface superconductivity and vortex lattice in the Weyl semimetal -PtBi
Jose Antonio Moreno, Pablo García Talavera, Edwin Herrera +8
The layered compound -PtBi is a topological semimetal with Fermi arcs at the surface joining bulk Weyl points. Recent work has found signatures of surface superconductivity…
Gapless superconductivity from extremely dilute magnetic disorder in 2H-NbSe2-xSx
Jose Antonio Moreno, Mercè Roig, Víctor 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…
Superconducting density of states of PtPb4
Pablo García Talavera, Jose Antonio Moreno, Edwin Herrera +5
PtPb is a type II superconductor with a bulk critical temperature K and an upper critical field of T. PtPb is related to non-superconducting…
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…
Revealing inter-band electron pairing in a superconductor with spin-orbit coupling
Javier Zaldívar, Jon Ortuzar, Miguel Alvarado +8
Most superconducting mechanisms pair electrons within the same band, forming spin singlets. However, the discovery of multi-band superconductivity has opened new scenarios for pair…
Misfit layer superconductors, tuneable bulk heterostructures with strong 2D effects
Tomas Samuely, Martin Gmitra, Tristan Cren +2
Atomically thin layered materials are systems with zero limit bulk-to-surface ratio. Their physical properties are determined by two-dimensionality and strongly affected by interfa…
Field-induced antiferromagnetic correlations in a nanopatterned van der Waals ferromagnet: a potential artificial spin ice
Avia Noah, Nofar Fridman, Yishay Zur +15
Nano-patterned magnetic materials have opened new venues on the investigation of strongly correlated phenomena including artificial spin-ice systems, geometric frustration, magneti…
Anomalous size dependence of the coercivity of nanopatterned CrGeTe3
Avia Noah, Nofar Fridman, Yishay Zur +8
The coercivity of single-domain magnetic nanoparticles typically decreases with the nanoparticle size and reaches zero when thermal fluctuations overcome the magnetic anisotropy. H…

Stefano Trivini, Jon Ortuzar, Javier Zaldivar +5
Magnetic adatoms on s-wave superconductors induce bound states inside the superconducting gap, called Yu-Shiba-Rusinov states (YSR). The anisotropy of the Fermi surface determines…
Anti-hyperuniform diluted vortex matter induced by correlated disorder

Disordered hyperuniform materials are very promising for applications but the successful route for synthesizing them requires to understand the interactions induced by the host med…
Conductance of atomic size contacts of Ag and Au at high magnetic fields
Beilun Wu, Andrés Martínez, 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…
