Linear response function around a localized impurity in a superconductor
G. G. N. Angilella, F. E. Leys, N. H. March +1
Imaging the effects of an impurity like Zn in high-Tc superconductors [Nature 61 (2000) 746] has rekindled interest in defect problems in the superconducting phase. This has prompt…
Gaussian Effective Potential and superconductivity
M. Camarda, G. G. N. Angilella, R. Pucci +1
The Gaussian Effective Potential in a fixed transverse unitarity gauge is studied for the static three-dimensional U(1) scalar electrodynamics (Ginzburg-Landau phenomenological the…
Symmetry breaking and restoring under high pressure: the amazing behaviour of the "simple" alkali metals
G. G. N. Angilella, F. Siringo, R. Pucci
We argue that an ionic lattice surrounded by a Fermi liquid changes phase several times under pressure, oscillating between the symmetric phase and a low-symmetry dimerized structu…
Effects of an electronic topological transition for anisotropic low-dimensional superconductors
G. G. N. Angilella, E. Piegari, A. A. Varlamov
We study the superconducting properties of a two-dimensional superconductor in the proximity to an electronic topological transition (ETT). In contrast to the 3D case, we find that…
Effect of strain-induced electronic topological transitions on the superconducting properties of LaSrCuO thin films
G. G. N. Angilella, G. Balestrino, P. Cermelli +2
We propose a Ginzburg-Landau phenomenological model for the dependence of the critical temperature on microscopic strain in tetragonal high-Tc cuprates. Such a model is in agreemen…
