Bad metallicity in the semi-quantum regime of the Hubbard model
Evyatar Tulipman, Vadim Oganesyan, Thomas P. Devereaux +1
Bad metals exhibit approximately -linear dc resistivity beyond the Ioffe--Regel limit. That this behavior occurs in systems with radically different ground states suggests it is…
Extended strange metal regime from superconducting puddles
Noga Bashan, Evyatar Tulipman, Steven A. Kivelson +2
We study a model of mesoscale superconducting puddles in a metal, represented as dynamical impurities interacting with a finite number of electronic channels via Andreev and normal…
Solvable models of two-level systems coupled to itinerant electrons: Robust non-Fermi liquid and quantum critical pairing
Evyatar Tulipman, Noga Bashan, Jörg Schmalian +1
Strange metal behavior is traditionally associated with an underlying putative quantum critical point at zero temperature. However, in many correlated metals, e.g., high-Tc cuprate…
Tunable non-Fermi liquid phase from coupling to two-level systems
Noga Bashan, Evyatar Tulipman, Jörg Schmalian +1
We study a controlled large- theory of electrons coupled to dynamical two-level systems (TLSs) via spatially-random interactions. Such a physical situation arises when electrons…
Investigation of Planckian behavior in a high-conductivity oxide: PdCrO
Elina Zhakina, Ramzy Daou, Antoine Maignan +12
The layered delafossite metal PdCrO is a natural heterostructure of highly conductive Pd layers Kondo coupled to localized spins in the adjacent Mott insulating CrO layers.…
linear resistivity from magneto-elastic scattering: application to PdCrO
J. F. Mendez-Valderrama, Evyatar Tulipman, Elina Zhakina +3
An electronic solid with itinerant carriers and localized magnetic moments represents a paradigmatic strongly correlated system. The electrical transport properties associated with…
A Criterion for Strange Metallicity in the Lorenz Ratio
Evyatar Tulipman, Erez Berg
The Wiedemann-Franz (WF) law, stating that the Lorenz ratio between the thermal and electrical conductivities in a metal approaches a universal constant $L_0=π^2 k_B^2…
Strongly coupled phonon fluid and Goldstone modes in an anharmonic quantum solid: transport and chaos
Evyatar Tulipman, Erez Berg
We study properties of thermal transport and quantum many-body chaos in a lattice model with oscillators per site, coupled by strong anharmonic terms. We first conside…
Strongly coupled quantum phonon fluid in a solvable model
Evyatar Tulipman, Erez Berg
We study a model of a large number of strongly coupled phonons that can be viewed as a bosonic variant of the Sachdev-Ye-Kitaev model. We determine the phase diagram of the model w…
