Evidence for freezing of charge degrees of freedom across a critical point in CeCoIn
Nikola Maksimovic, Tessa Cookmeyer, Jan Rusz +10
The presence of a quantum critical point separating two distinct zero-temperature phases is thought to underlie the `strange' metal state of many high-temperature superconductors.…
Quantum Chaos in a Rydberg Atom System
Yochai Werman
A recent proposal by Hallam et al. suggested using the chaotic properties of the semiclassical equations of motion, obtained by the time dependent variational principle (TDVP), as…
From eigenstate thermalization to hydrodynamic transport in correlated metals
Yochai Werman, Shubhayu Chatterjee, Ehud Altman
We present a new framework for computing low frequency transport properties of strongly correlated, ergodic systems. Our main assumption is that, when a thermalizing diffusive syst…
Translationally invariant non-Fermi liquid metals with critical Fermi-surfaces: Solvable models
Debanjan Chowdhury, Yochai Werman, Erez Berg +1
We construct examples of translationally invariant solvable models of strongly-correlated metals, composed of lattices of Sachdev-Ye-Kitaev dots with identical local interactions.…
Signatures of fractionalization in spin liquids from interlayer thermal transport
Yochai Werman, Shubhayu Chatterjee, Siddhardh C. Morampudi +1
Quantum spin liquids (QSLs) are intriguing phases of matter possessing fractionalized excitations. Several quasi-two dimensional materials have been proposed as candidate QSLs, but…
Quantum chaos in an electron-phonon bad metal
Yochai Werman, Steven A. Kivelson, Erez Berg
We calculate the scrambling rate and the butterfly velocity associated with the growth of quantum chaos for a solvable large- electron-phonon system. We study a temp…
Non-quasiparticle transport and resistivity saturation: A view from the large-N limit
Yochai Werman, Steven A. Kivelson, Erez Berg
The electron dynamics in metals are usually well described by the semiclassical approximation for long-lived quasiparticles. However, in some metals, the scattering rate of the ele…
The Mott-Ioffe-Regel limit and resistivity crossover in a tractable electron-phonon model
Yochai Werman, Erez Berg
Many metals display resistivity saturation - a substantial decrease in the slope of the resistivity as a function of temperature, that occurs when the electron scattering rate $τ^{…
Exciton Quasi-Condensation in One Dimensional Systems
Yochai Werman, Erez Berg
A quasi-exciton condensate is a phase characterized by quasi-long range order of an exciton (electron-hole pair) order parameter. Such a phase can arise naturally in a system of tw…
