Journal ArticleDOI
Resonating-valence-bond theory of phase transitions and superconductivity in La 2 CuO 4 -based compounds
TL;DR: The mysterious high-T ``twitch'' transition in La 2 is identified with the mean-field resonating-valence-bond transition of the Heisenberg model of Baskaran, Zou, and Anderson with structure distortions caused by Coulomb correlations of the pair wave function.
Journal ArticleDOI
Gauge theory of high-temperature superconductors and strongly correlated Fermi systems.
TL;DR: This paper shows that the development of resonating valence bond correlations and the subsequent superconducting order in the high-T/sub c/ oxide superconductors are described by an U(1) lattice gauge theory.
Journal ArticleDOI
Exact results for spin dynamics and fractionalization in the kitaev model
TL;DR: In spite of the presence of gapless propagating Majorana fermion excitations, dynamical two spin correlation functions are identically zero beyond nearest neighbor separation, which shows existence of a gapless but short range spin liquid.
Journal ArticleDOI
Novel electric field effects on Landau levels in graphene.
TL;DR: The theoretical results, strikingly different from the standard 2D electron gas, are explained using a "Lorentz boost," and as an "instability of a relativistic quantum field vacuum."
Journal ArticleDOI
Electronic model for CoO2 layer based systems: chiral resonating valence bond metal and superconductivity.
TL;DR: It is suggested that at optimal doping chiral spin fluctuations enhanced by the dopant dynamics lead to a gapful d-wave superconducting state.
