Large theory of critical Fermi surfaces II: conductivity
Haoyu Guo, Aavishkar A. Patel, Ilya Esterlis +1
A Fermi surface coupled to a scalar field can be described in a expansion by choosing the fermion-scalar Yukawa coupling to be random in the -dimensional flavor space, but…
Universal theory of strange metals from spatially random interactions
Aavishkar A. Patel, Haoyu Guo, Ilya Esterlis +1
We consider two-dimensional metals of fermions coupled to quantum critical scalars, the latter representing order parameters or emergent gauge fields. We show that at low temperatu…
Resonant thermal Hall effect of phonons coupled to dynamical defects
Haoyu Guo, Darshan G. Joshi, Subir Sachdev
We present computations of the thermal Hall coefficient of phonons scattering off a defect with multiple energy levels. Using a microscopic formulation based on the Kubo formula, w…
Extrinsic phonon thermal Hall transport from Hall viscosity
Haoyu Guo, Subir Sachdev
Motivated by recent experiments on the phonon contribution to the thermal Hall effect in the cuprates, we present an analysis of chiral phonon transport. We assume the chiral behav…
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.…
Excitation spectra of quantum matter without quasiparticles II: random - models
Maria Tikhanovskaya, Haoyu Guo, Subir Sachdev +1
We present numerical solutions of the spectral functions of - models with random and all-to-all exchange and global SU() spin rotation symmetry. The solutions are obtained…
Excitation spectra of quantum matter without quasiparticles I: Sachdev-Ye-Kitaev models
Maria Tikhanovskaya, Haoyu Guo, Subir Sachdev +1
We study the low frequency spectra of complex Sachdev-Ye-Kitaev (SYK) models at general densities. The analysis applies also to SU() magnets with random exchange at large . T…
Linear in temperature resistivity in the limit of zero temperature from the time reparameterization soft mode
Haoyu Guo, Yingfei Gu, Subir Sachdev
The most puzzling aspect of the 'strange metal' behavior of correlated electron compounds is that the linear in temperature resistivity often extends down to low temperatures, lowe…
Gauge Theories for the Thermal Hall Effect
Haoyu Guo, Rhine Samajdar, Mathias S. Scheurer +1
We consider the thermal Hall effect of fermionic matter coupled to emergent gauge fields in 2+1 dimensions. While the low-temperature thermal Hall conductivity of bulk topological…
Transport and chaos in lattice Sachdev-Ye-Kitaev models
Haoyu Guo, Yingfei Gu, Subir Sachdev
We compute the transport and chaos properties of lattices of quantum Sachdev-Ye-Kitaev islands coupled by single fermion hopping, and with the islands coupled to a large number of…
Enhanced thermal Hall effect in the square-lattice Néel state
Rhine Samajdar, Mathias S. Scheurer, Shubhayu Chatterjee +3
Recent experiments on several cuprate compounds have identified an enhanced thermal Hall response in the pseudogap phase. Most strikingly, this enhancement persists even in the und…
