Journal ArticleDOI
Quantum phase transitions in frustrated two-dimensional antiferromagnets
TL;DR: In this paper, frustrated, two-dimensional, quantum antiferromagnets in the vicinity of a quantum transition from a non-collinear, magnetically-ordered ground state to a quantum disordered phase are described.
Journal ArticleDOI
Pseudogap and Fermi surface topology in the two-dimensional Hubbard model
Wei Wu,Wei Wu,Mathias S. Scheurer,Shubhayu Chatterjee,Subir Sachdev,Subir Sachdev,Subir Sachdev,Antoine Georges,Michel Ferrero,Michel Ferrero +9 more
TL;DR: In this paper, it was shown that the pseudogap only exists when the Fermi surface is holelike and that, for a broad range of parameters, its opening is concomitant with a topology change from electronlike to holelike.
Journal ArticleDOI
Fluctuating spin density waves in metals
TL;DR: The phase diagram of the SU(2) gauge theory as discussed by the authors shows that the onset of spin density wave order in the Fermi liquid occurs either directly, in the framework discussed by Hertz, or via intermediate non-Fermi-liquid phases of fractionalized excitations.
Journal ArticleDOI
Hole motion in a quantum Néel state.
TL;DR: The spin-wave expansion is used to motivate a simple trial wave function for the N\'eel ground state of a spin-1/2 Heisenberg antiferromagnet on a square lattice, which yields an upper bound on the ground-state energy per bond.
Journal ArticleDOI
Evolution of Quantum Fluctuations Near the Quantum Critical Point of the Transverse Field Ising Chain System CoNb$_2$O$_6$
A. W. Kinross,M. Fu,Timothy J. S. Munsie,H. A. Dabkowska,Graeme Luke,Subir Sachdev,Takashi Imai +6 more
TL;DR: In this paper, the authors map the evolution of quantum fluctuations in the transverse field Ising chain (TFIC) based on Nuclear Magnetic Resonance (NMR) measurements of CoNb$_2$O$_6, and demonstrate the finite temperature effects on quantum criticality.
