Cross-band versus intra-band pairing in superconductors: signatures and consequences of the interplay
A. A. Vargas-Paredes, A. A. Shanenko, A. Vagov +2
We analyze the paradigmatic competition between intra-band and cross-band Cooper-pair formation in two-band superconductors, neglected in most works to date. We derive the phase-se…
Shape-resonant superconductivity in nanofilms: from weak to strong coupling
Marco Cariglia, Alfredo A. Vargas-Paredes, Mauro M. Doria +3
Ultrathin superconductors of different materials are becoming a powerful platform to find mechanisms for enhancement of superconductivity, exploiting shape resonances in different…
Zero helicity states in the interface
Edinardo I. B. Rodrigues, Alfredo A. Vargas-Paredes, Mauro M. Doria +1
We propose a kinetically driven mechanism based on the breaking of the spatial reflection symmetry to describe the magnetic moment and the torque observed by Lu-Li et al. (Ref. 1)…
Coexistence of magnetic and charge order in a two-component order parameter description of the layered superconductors
Mauro M. Doria, Alfredo A. Vargas-Paredes, Marco Cariglia
A two-component order parameter approach for the layered superconductor is shown to form a condensate with magnetic and charge degrees of freedom. This condensate is an inhomogeneo…
Is the pseudogap a topological state?
Alfredo. A. Vargas-Paredes, Marco Cariglia, Mauro M. Doria
We conjecture that the pseudogap is an inhomogeneous condensate above the homogeneous state whose existence is granted by topological stability. We consider the simplest possible o…
Evidence for skyrmions in the high-temperature superconductors
Alfredo A. Vargas-Paredes, Marco Cariglia, Mauro M. Doria +2
We claim that the charge density wave recently found by resonant soft x-ray scattering in layered copper oxides is the tetragonal symmetry defined by the distance between neighbor…
