We study the properties of fermion correlators in a boundary theory dual to the Reissner-Nordstrom AdS{sub d+1} background in the presence of a bulk dipole (Pauli) interaction term with strength p .…
Orbital ordering induces structural phase transition and the resistivity anomaly in iron pnictides

We attribute the structural phase transition (SPT) in the parent compounds of the iron pnictides to orbital ordering. Due to the anisotropy of the $d_{xz}$ and $d_{yz}$ orbitals in the $xy$ plane, a…
Colloquium: Identifying the propagating charge modes in doped Mott insulators

High-temperature superconductivity in the copper-oxide ceramics remains an unsolved problem because we do not know what the propagating degrees of freedom are in the normal state. As a result, we do…
Orbital ordering and unfrustrated (π,0) magnetism from degenerate double exchange in the iron pnictides

The magnetic excitations of the iron pnictides are explained within a degenerate double-exchange model. The local-moment spins are coupled by superexchanges J{sub 1} and J{sub 2} between nearest and…
Exact theory for superconductivity in a doped Mott insulator

Because the cuprate superconductors are doped Mott insulators, it would be advantageous to solve even a toy model that exhibits both Mottness and superconductivity. We consider the Hatsugai–Kohmoto…
Un-Fermi liquids: Unparticles in strongly correlated electron matter
- P. Phillips, B. Langley, J. Hutasoit

- 30 April 2013
Since any non-trivial infrared dynamics in strongly correlated electron matter must be controlled by a critical fixed point, we argue that the form of the single-particle propagator can be deduced…
Orbitally and magnetically induced anisotropy in iron-based superconductors
- W. Lv, P. Phillips
- Physics, Geology
- 23 May 2011
Recent experimental developments in the iron pnictides have unambiguously demonstrated the existence of in-plane electronic anisotropy in the absence of the long-range magnetic order. Such anisotropy…
Mottness in high-temperature copper-oxide superconductors

- 13 February 2009
The standard theory of metals, Fermi liquid theory, hinges on the key assumption that although the electrons interact, the low-energy excitation spectrum stands in a one-to-one correspondence with…
