The flow of local quantum fluids: Conservation laws and vertex corrections from many-body linear-response theory with local self-energy
Davide Valentinis
In non-diffusive conduction regimes of strongly correlated quantum electron systems, electromagnetic perturbations simultaneously probe the electronic dynamics in time and space: t…
Superlinear Hall angle and carrier mobility from non-Boltzmann magnetotransport in the spatially disordered Yukawa-Sachdev-Ye-Kitaev model on a square lattice
Davide Valentinis, Jörg Schmalian, Subir Sachdev +1
Exact numerical results for the dc magnetoconductivity tensor of the two-dimensional spatially disordered Yukawa-Sachdev-Ye-Kitaev (2D-YSYK) model on a square lattice, at first ord…
Strange metal and superconductor in the two-dimensional Yukawa-Sachdev-Ye-Kitaev model
Chenyuan Li, Davide Valentinis, Aavishkar A. Patel +4
The two-dimensional Yukawa-Sachdev-Ye-Kitaev (2d-YSYK) model provides a universal theory of quantum phase transitions in metals in the presence of quenched random spatial fluctuati…
On non-local electrical transport in anisotropic metals
Graham Baker, Davide Valentinis, Andrew P. Mackenzie
We discuss various aspects of non-local electrical transport in anisotropic metals. For a metal with circular Fermi surface, the scattering rates entering the local conductivity an…
Cyclotron resonance and quantum oscillations of critical Fermi surfaces
Haoyu Guo, Davide Valentinis, Jörg Schmalian +2
Kohn's theorem places strong constraints on the cyclotron response of Fermi liquids. Recent observations of a doping dependence in the cyclotron mass of LaSrCuO (Le…
BCS to incoherent superconductivity crossovers in the Yukawa-SYK model on a lattice
Davide Valentinis, Gian Andrea Inkof, Jörg Schmalian
We provide a quantitative and controlled analysis of the phase diagram of the the Yukawa-SYK model on a lattice, in the normal and superconducting states. We analyze the entire cro…
Correlation between phase stiffness and condensation energy across the non-Fermi to Fermi-liquid crossover in the Yukawa-Sachdev-Ye-Kitaev model on a lattice
Davide Valentinis, Gian Andrea Inkof, Jörg Schmalian
We construct and analyze a lattice generalization of the Yukawa-Sachdev-Ye-Kitaev model, where spinful fermions experience on-site, random, all-to-all interactions with an Einstein…
Non-local electrodynamics in ultra-pure PdCoO
Graham Baker, Timothy W. Branch, J. S. Bobowski +11
The motion of electrons in the vast majority of conductors is diffusive, obeying Ohm's law. However, the recent discovery and growth of high-purity materials with extremely long el…
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…
Propagation of shear stress in strongly interacting metallic Fermi liquids enhances transmission of terahertz radiation
D. Valentinis, J. Zaanen, D. van der Marel
A highlight of Fermi-liquid phenomenology, as explored in neutral He, is the observation that in the collisionless regime shear stress propagates as if one is dealing with the…
Optical signatures of shear collective modes in strongly interacting Fermi liquids
D. Valentinis
The concept of Fermi liquid lays a solid cornerstone to the understanding of electronic correlations in quantum matter. This ordered many-body state rigorously organizes electrons…
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…
Modulation of the superconducting critical temperature due to quantum confinement at the LaAlO/SrTiO interface
D. Valentinis, S. Gariglio, A. Fête +3
Superconductivity develops in bulk doped SrTiO and at the LaAlO/SrTiO interface with a dome-shaped density dependence of the critical temperature , despite differe…
Rise and fall of shape resonances in thin films of BCS superconductors
D. Valentinis, D. van der Marel, C. Berthod
The confinement of a superconductor in a thin film changes its Fermi-level density of states and is expected to change its critical temperature . Previous calculations have re…

Davide Forcella, Jan Zaanen, Davide Valentinis +1
We provide a general theoretical framework to describe the electromagnetic properties of viscous charged fluids, consisting for example of electrons in certain solids or plasmas. W…
