Correlation effects in the iron pnictides
Qimiao Si, Elihu Abrahams, Jianhui Dai +1
One of the central questions about the iron pnictides concerns the extent to which their electrons are strongly correlated. Here we address this issue through the phenomenology of…
Iron pnictides as a new setting for quantum criticality
Jianhui Dai, Qimiao Si, Jian-Xin Zhu +1
Two major themes in the physics of condensed matter are quantum critical phenomena and unconventional superconductivity. These usually occur in the context of competing interaction…
Strong Correlations and Magnetic Frustration in the High Tc Iron Pnictides
Qimiao Si, Elihu Abrahams
We consider the iron pnictides in terms of a proximity to a Mott insulator. The superexchange interactions contain competing nearest-neighbor and next-nearest-neighbor components.…
Effect of impurities on supersolid condensate: a Ginzburg-Landau approach
Alexander V. Balatsky, Elihu Abrahams
Basing our arguments on a wave function that contains both positional and superfluid order, we propose a Ginzburg-Landau functional for a supersolid with the two order parameters n…
Condensation energy and the mechanism of superconductivity
Sudip Chakravarty, Hae-Young Kee, Elihu Abrahams
Condensation energy in a superconductor cannot be precisely defined if mean-field theory fails to hold. This implies that in the case of high temperature superconductors, discussio…
