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…
Fractionalized Fermi liquids and the cuprate phase diagram
Pietro M. Bonetti, Maine Christos, Alexander Nikolaenko +2
We review a theoretical framework for the cuprate superconductors, rooted in a fractionalized Fermi liquid (FL*) description of the intermediate-temperature pseudogap phase at low…
Thermopower across Fermi-volume-changing quantum phase transitions without translational symmetry breaking
Peter Lunts, Aavishkar A. Patel, Subir Sachdev
We describe the evolution of low-temperature thermopower across Fermi-volume-changing quantum phase transitions in Kondo lattice models without translational symmetry breaking. Thi…
Strange metals and planckian transport in a gapless phase from spatially random interactions
Aavishkar A. Patel, Peter Lunts, Michael S. Albergo
`Strange' metals that do not follow the predictions of Fermi liquid theory are prevalent in materials that feature superconductivity arising from electron interactions. In recent y…
Enhanced Strange Metallicity due to Hubbard-U Coulomb Repulsion
Andrew Hardy, Olivier Parcollet, Antoine Georges +1
We solve a model of electrons with Hubbard- Coulomb repulsion and a random Yukawa coupling to a two-dimensional bosonic bath, using an extended dynamical mean field theory schem…

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…
Localization of overdamped bosonic modes and transport in strange metals
Aavishkar A. Patel, Peter Lunts, Subir Sachdev
A recent theory described strange metal behavior in a model of a Fermi surface coupled a two-dimensional quantum critical bosonic field with a spatially random Yukawa coupling. Wit…
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…
Theory of shot noise in strange metals
Alexander Nikolaenko, Subir Sachdev, Aavishkar A. Patel
We extend the theory of shot noise in coherent metals to shot noise in strange metals without quasiparticle excitations. This requires a generalization of the Boltzmann equation wi…
Large theory of critical Fermi surfaces
Ilya Esterlis, Haoyu Guo, Aavishkar A. Patel +1
We describe the large saddle point, and the structure of fluctuations about the saddle point, of a theory containing a sharp, critical Fermi surface in two spatial dimensions.…
Thermoelectric power of Sachdev-Ye-Kitaev islands: Probing Bekenstein-Hawking entropy in quantum matter experiments
Alexander Kruchkov, Aavishkar Patel, Philip Kim +1
The Sachdev-Ye-Kitaev (SYK) model describes electrons with random and all-to-all interactions, and realizes a many-body state without quasiparticle excitations, and a non-vanishing…

A theoretical understanding of the enigmatic linear-in-temperature () resistivity, ubiquitous in strongly correlated metallic systems, has been a long sought-after goal. Further…
Many-body chaos in the antiferromagnetic quantum critical metal
Peter Lunts, Aavishkar A. Patel
We compute the scrambling rate at the antiferromagnetic (AFM) quantum critical point, using the fixed point theory of Phys. Rev. X , 021010 (2017). At this strongly…

Hydrodynamic flows of non-Fermi liquids: magnetotransport and bilayer drag
Aavishkar A. Patel, Richard A. Davison, Alex Levchenko
We consider a hydrodynamic description of transport for generic two dimensional electron systems that lack Galilean invariance and do not fall into the category of Fermi liquids. W…
