Quantum discontinuity fixed point and renormalization group flow of the SYK model
Roman Smit, Davide Valentinis, Jörg Schmalian +1
We determine the global renormalization group (RG) flow of the Sachdev-Ye-Kitaev (SYK) model. This flow allows for an understanding of the surprising role of critical slowing down…

Periodicity of superconducting shape resonances in thin films
D. Valentinis, C. Berthod
The pairing temperature of superconducting thin films is expected to display, within the Bardeen-Cooper-Schrieffer theory, oscillations as a function of the film thickness. We show…

Modulation of superconductivity by quantum confinement in doped strontium titanate
Davide Valentinis, Zhenping Wu, Stefano Gariglio +6
Quantum confinement in a thin-film geometry offers viable routes for tuning the critical properties of superconductors through modification of both density of states and pairing in…
