Superconducting dome due to the Fano-Feshbach shape resonance in artificial high-Tc superlattices
Gaetano Campi, Andrea Alimenti, Danielle Villa +7
In this work we provide compelling experimental validation of the Bianconi Perali Valletta (BPV) theory predicting a superconducting dome based on a quantum material design of Arti…
High magnetic field response of superconductivity dome in quantum artificial High Tc superlattices with variable geometry
Gaetano Campi, Andrea Alimenti, Sang-Eon Lee +5
It is known that cuprate artificial high Tc superlattices (AHTS) with period d, composed of quantum wells confining interface space charge in stoichiometric Mott insulator layers (…
Lattice Quantum Geometry Controlling 118 K Multigap Superconductivity in Heavily Overdoped CuBa2Ca3Cu4O10+d
Gaetano Campi, Massimiliano Catricala, Giuseppe Chita +5
Synchrotron X-ray diffraction has been used to study the thermal structure evolution in CuBa2Ca3Cu4O10+d (Cu1234), a superconductor which exhibits a high critical temperature (Tc 1…
Nanoscale lattice heterostructure in high Tc superconductors
Annette Bussmann-Holder, Jürgen Haase, Hugo Keller +9
Low temperature superconductivity was known since 1957 to be described by BCS theory for an effective single band metals controlled by the density of states at the Fermi level, ver…
Upper critical magnetic field and multiband superconductivity in artificial high-Tc superlattices of nano quantum wells
G. Campi, A. Alimenti, G. Logvenov +10
Artificial high-Tc superlattices (AHTS) composed of quantum building blocks with tunable superconducting critical temperature have been synthesized by engineering their nanoscale g…
Josephson coupling in Lanthanum-based cuprates superlattices
Halima Giovanna Ahmad, Davide Massarotti, Francesco Tafuri +3
In most anisotropic compounds such as bismuth-based layered cuprate perovskites, the supercurrent across the blocking layer is of Josephson type, and a single crystal forms a natur…
