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…

Ultraviolet/infrared mixing-driven suppression of Kondo screening in the antiferromagnetic quantum critical metal
Francisco Borges, Peter Lunts, Sung-Sik Lee
We study a magnetic impurity immersed in the two-dimensional antiferromagnetic quantum critical metal (AFQCM), using the field-theoretic functional renormalization group. Critical…

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…
