Critical behavior of an impurity at the boson superfluid-Mott insulator transition
Seth Whitsitt, Subir Sachdev
We present a universal theory for the critical behavior of an impurity at the two-dimensional superfluid-Mott insulator transition. Our analysis is motivated by a numerical study o…
Fermionic spinon theory of square lattice spin liquids near the Néel state
Alex Thomson, Subir Sachdev
Quantum fluctuations of the Néel state of the square lattice antiferromagnet are usually described by a theory of bosonic spinons coupled to a U(1) gauge field, and…
Quantum quench of the Sachdev-Ye-Kitaev Model
Andreas Eberlein, Valentin Kasper, Subir Sachdev +1
We describe the non-equilibrium dynamics of the Sachdev-Ye-Kitaev models of fermions with all-to-all interactions. These provide tractable models of the dynamics of quantum systems…
Thermal diffusivity and chaos in metals without quasiparticles
Mike Blake, Richard A. Davison, Subir Sachdev
We study the thermal diffusivity in models of metals without quasiparticle excitations (`strange metals'). The many-body quantum chaos and transport properties of such metals…
Intertwining topological order and broken symmetry in a theory of fluctuating spin density waves
Shubhayu Chatterjee, Subir Sachdev, Mathias Scheurer
The pseudogap metal phase of the hole-doped cuprate superconductors has two seemingly unrelated characteristics: a gap in the electronic spectrum in the `anti-nodal' region of the…
