Deconfined criticality between an antiferromagnetic insulator and a nodal d-wave superconductor: a quantum Monte Carlo study
Chuang Chen, Subir Sachdev, Zi Yang Meng
We present a quantum Monte Carlo study of the transition between the insulating Néel state and the nodal -wave superconductor on the square lattice at half-filling. We access a…
Emergence of nodal Bogoliubov quasiparticles across the transition from the pseudogap metal to the d-wave superconductor
Maine Christos, Subir Sachdev
We model the pseudogap state of the hole- and electron-doped cuprates as a metal with hole and/or electron pocket Fermi surfaces. In the absence of long-range antiferromagnetism, s…
A model of -wave superconductivity, antiferromagnetism, and charge order on the square lattice
Maine Christos, Zhu-Xi Luo, Henry Shackleton +3
Early studies proposed a connection between cuprate superconductivity and fractionalized spin liquid states. But the low temperature phase diagram is dominated by states without fr…
Electronic spectra with paramagnon fractionalization in the single band Hubbard model
Eric Mascot, Alexander Nikolaenko, Maria Tikhanovskaya +3
We examine the spectral properties of a recently proposed theory of the intermediate temperature pseudogap metal phase of the cuprates. We show that this theory can be obtained fro…
Quantum statistical mechanics of the Sachdev-Ye-Kitaev model and charged black holes
Subir Sachdev
This review is a contribution to a book dedicated to the memory of Michael E. Fisher. The first example of a quantum many body system not expected to have any quasiparticle excitat…
Hidden orders and phase transitions for the fully packed quantum loop model on the triangular lattice
Xiaoxue Ran, Zheng Yan, Yan-Cheng Wang +5
Quantum loop and dimer models are prototypical correlated systems with local constraints, which are not only intimately connected to lattice gauge theories and topological orders b…
