The enigma of the pseudogap phase of the cuprate superconductors
Debanjan Chowdhury, Subir Sachdev
The last few years have seen significant experimental progress in characterizing the copper-based hole-doped high temperature superconductors in the regime of low hole density, p.…
Higgs criticality in a two-dimensional metal
Debanjan Chowdhury, Subir Sachdev
We analyze a candidate theory for the strange metal near optimal hole-doping in the cuprate superconductors. The theory contains a quantum phase transition between metals with larg…
Wess-Zumino-Witten Terms in Graphene Landau Levels
Junhyun Lee, Subir Sachdev
We consider the interplay between the antiferromagnetic and Kekulé valence bond solid orderings in the zero energy Landau levels of neutral monolayer and bilayer graphene. We estab…
Conductivity of weakly disordered strange metals: from conformal to hyperscaling-violating regimes
Andrew Lucas, Subir Sachdev
We present a semi-analytic method for constructing holographic black holes that interpolate from anti-de Sitter space to hyperscaling-violating geometries. These are holographic du…
Charge ordering in three-band models of the cuprates
Alexandra Thomson, Subir Sachdev
We examine trends in the wavevectors and form-factors of charge density wave instabilities of three-band models of the underdoped cuprates. For instabilities from a high temperatur…
Density-wave instabilities of fractionalized Fermi liquids
Debanjan Chowdhury, Subir Sachdev
Recent experiments in the underdoped regime of the hole-doped cuprates have found evidence for an incommensurate charge density wave state. We present an analysis of the charge ord…
