Scaling of the thermal spectral function for quantum critical bosons in one dimension
Thomas Barthel, Ulrich Schollwöck, Subir Sachdev
We present an improved scheme for the precise evaluation of finite-temperature response functions of strongly correlated systems in the framework of the time-dependent density matr…
The quasi-normal modes of quantum criticality
William Witczak-Krempa, Subir Sachdev
We study charge transport of quantum critical points described by conformal field theories in 2+1 spacetime dimensions. The transport is described by an effective field theory on a…
Keldysh approach for non-equilibrium phase transitions in quantum optics: beyond the Dicke model in optical cavities
Emanuele G. Dalla Torre, Sebastian Diehl, Mikhail D. Lukin +2
We investigate non-equilibrium phase transitions for driven atomic ensembles, interacting with a cavity mode, coupled to a Markovian dissipative bath. In the thermodynamic limit an…
Compressible quantum phases from conformal field theories in 2+1 dimensions
Subir Sachdev
Conformal field theories (CFTs) with a globally conserved U(1) charge Q can be deformed into compressible phases by modifying their Hamiltonian, H, by a chemical potential H -> H -…
Quantum criticality of reconstructing Fermi surfaces in antiferromagnetic metals
Junhyun Lee, Philipp Strack, Subir Sachdev
We present a functional renormalization group analysis of a quantum critical point in two-dimensional metals involving Fermi surface reconstruction due to the onset of spin-density…
Breakdown of Fermi liquid behavior at the (π,π)=2k_F spin-density wave quantum-critical point: the case of electron-doped cuprates
Dominic Bergeron, Debanjan Chowdhury, Matthias Punk +2
Many correlated materials display a quantum critical point between a paramagnetic and a SDW state. The SDW wave vector connects points (hot spots) on opposite sides of the Fermi su…
