The foot, the fan, and the cuprate phase diagram: Fermi-volume-changing quantum phase transitions
Subir Sachdev
A Fermi liquid with a 'large' Fermi surface (FL) can have a quantum phase transition to a spin density wave state (SDW) with reconstructed 'small' Fermi pockets. Both FL and SDW ph…

Lectures on the quantum phase transitions of metals
Subir Sachdev
Quantum phase transitions of metals involve changes in the Fermi surface, and can be divided into three categories. The first two categories involve symmetry breaking, and lead to…
