Giant second-harmonic generation in few-atomic layer metals
Alessio Zaccone
Quantum confinement restructures the electronic phase space of ultrathin metals, but the resulting density-of-states (DOS) change is not generically large. We show that, within a t…
Electrical transport in ultra-thin films: from Fuchs-Sondheimer to quantum-confinement
Alessio Zaccone
Ultra-thin films are fundamental components of modern nanoelectronics, where reducing thickness to the few-nanometer scale leads to a dramatic increase in electrical resistivity. F…
Universal inverse-cube thickness scaling of projectile penetration energy in ultrathin films
Alessio Zaccone, Tim W. Sirk
Ultrathin films of widely different materials exhibit a dramatic enhancement of projectile penetration resistance under high--velocity impact. Despite extensive simulations and exp…
Turning non-superconducting elements into superconductors by quantum confinement and proximity
Giovanni A. Ummarino, Alessio Zaccone
Elemental good metals, including noble metals (Cu, Ag, Au) and several -block elements, do not exhibit superconductivity in bulk at ambient pressure, mainly due to weak electron…
Phonon-confinement theory of thermal conductivity in ultrathin silicon films
Alessio Zaccone
The thermal properties of solids under nanoscale confinement are currently not understood at the atomic level. Recent numerical studies have highlighted the presence of a minimum i…
Eliashberg theory prediction of critical currents in superconducting thin films under DC electric fields
Giovanni Alberto Ummarino, Alessio Zaccone, Alessandro Braggio +1
Superconducting thin metallic films, functioning as supercurrent gate-tunable transistors, have considerable potential for future quantum electronic devices. Despite extensive rese…
Possible superconductivity in very thin magnesium films
Giovanni Alberto Ummarino, Alessio Zaccone
It is known that noble metals such as gold, silver and copper are not supercon- 1 ductors, so as magnesium. This is due to the weakness of the electron-phonon interaction 2 which m…
Microscopic mechanism of electric field-induced superconductivity suppression in metallic thin films
Alessio Zaccone, Giovanni A. Ummarino, Alessandro Braggio +1
Supercurrent field-effect transistors made from thin metallic films are a promising option for next-generation high-performance computation platforms. Despite extensive research, t…
Topological Bardeen-Cooper-Schrieffer theory of superconducting quantum rings
Elena Landro', Vladimir M. Fomin, Alessio Zaccone
Quantum rings have emerged as a playground for quantum mechanics and topological physics, with promising technological applications. Experimentally realizable quantum rings, albeit…
Can the noble metals (Au, Ag and Cu) be superconductors?
Giovanni A. Ummarino, Alessio Zaccone
It is common knowledge that noble metals are excellent conductors but do not exhibit superconductivity. On the other hand, quantum confinement in thin films has been consistently s…
Shear-induced diffusivity in supercooled liquids
Mangesh Bhendale, Jayant K. Singh, Alessio Zaccone
The Taylor-Aris theory of shear diffusion predicts that the effective diffusivity of a tracer molecule in a sheared liquid is enhanced by a term quadratic in the shear rate. In she…
