Non-Fermi liquid quasiparticles in strain-tuned Sr2RuO4
A. Hunter, C. Putzke, F. B. Kugler +23
Interacting electrons can form metallic states beyond the Fermi liquid paradigm, a conceptual frontier of many-body physics mainly explored via bulk thermodynamics and transport. I…

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…
