Room temperature multiferroicity in a transition metal dichalcogenide

G. Cardenas-Chirivi, K. Vega-Bustos, H. Rojas-Páez +8

The coexistence of multiple ferroic orders, i.e. multiferroicity, is a scarce property to be found in materials. Historically, this state has been found mainly in 3-dimensional com…

Quantum-well states at the surface of the heavy-fermion superconductor URuSi

Edwin Herrera-Vasco, Isabel Guillamón, Víctor Barrena +10

Electrons can form a two-dimensional electron gas at metal surfaces, where lateral confinement leads to quantum-well states. Such states have been observed for highly itinerant ele…

Direct observation of discommensurate charge density wave modulation in the quasi-1D Weyl semimetal candidate NbTe

J. A. Galvis, A. Fang, D. Jimenez-Guerrero +8

The transition-metal tetrachalcogenides are a model system to explore the conjunction of correlated electronic states such as charge density waves (CDW), with topological phases of…

Raman spectroscopy of few-layers TaS and Mo-doped TaS with enhanced superconductivity

S. Valencia-Ibáñez, D. Jimenez-Guerrero, J. D. Salcedo-Pimienta +6

The use of simple, fast and economic experimental tools to characterize low-dimensional materials is an important step in the process of democratizing the use of such materials in…

One-dimensional moire charge density wave in the hidden order state of URu2Si2 induced by fracture

Edwin Herrera, Victor Barrena, Isabel Guillamon +6

Moiré patterns can lead to fundamentally new electronic behavior when formed between two atomic lattices slightly shifted with respect to each other. A solid is however not just ch…

Thermal creep emerging from cooling a tilted vortex lattice in uniaxial superconductor

Roland Willa, Jose Augusto Galvis, Jose Benito-Llorens +3

A perturbed system relaxes towards an equilibrium given by a minimum in the potential energy landscape. This often occurs by thermally activated jumps over metastable states. The c…

Observation of a gel of quantum vortices in a superconductor at very low magnetic fields

José Benito Llorens, Lior Embon, Alexandre Correa +13

A gel consists of a network of particles or molecules formed for example using the sol-gel process, by which a solution transforms into a porous solid. Particles or molecules in a…

Attractive interaction between superconducting vortices in tilted magnetic fields

Alexandre Correa, Federico Mompean, Isabel Guillamon +8

Many practical applications of high T superconductors involve layered materials and magnetic fields applied on an arbitrary direction with respect to the layers. When the aniso…

Tilted vortex cores and superconducting gap anisotropy in 2H-NbSe2

J. A. Galvis, E. Herrera, C. Berthod +3

Superconducting vortex cores have been extensively studied for magnetic fields applied perpendicular to the surface by mapping the density of states (DOS) through Scanning Tunnelin…

Scale-invariant magnetoresistance in a cuprate superconductor

P. Giraldo-Gallo, J. A. Galvis, Z. Stegen +14

The anomalous metallic state in high-temperature superconducting cuprates is masked by the onset of superconductivity near a quantum critical point. Use of high magnetic fields to…

Subsurface bending and reorientation of tilted vortex lattices in the bulk due to Coulomb-like repulsion at the surface

E. Herrera, I. Guillamon, J. A. Galvis +6

We study vortex lattices (VLs) in superconducting weak-pinning platelet-like crystals of -BiPd in tilted fields with a Scanning Tunneling Microscope. We show that vortices…

Magnetic field dependence of the density of states in the multiband superconductor -BiPd

E. Herrera, I. Guillamon, J. A. Galvis +8

We present very low temperature scanning tunneling microscopy (STM) experiments on single crystalline samples of the superconductor -BiPd. We find a single fully isotropic s…

Tautochrone in the damped cycloidal pendulum

Paco H. Talero L, César A. Herreño-Fierro, Fernanda Santana

The tautochrone on a cycloid curve is usually considered without drag force. In this work, we investigate the motion of a damped cycloidal pendulum under presence of a drag force.…

International R&D Spillovers and other Unobserved Common Spillovers and Shocks

Diego-Ivan Ruge-Leiva

Studies which are based on Coe and Helpman (1995) and use weighted foreign R&D variables to estimate channel-specific R&D spillovers disregard the interaction between international…
