Fermi Surface Reconstruction by Dynamic Magnetic Fluctuations and Spin-Charge Separation Near an O(3) Quantum Critical Point
Michael Holt, Jaan Oitmaa, Wei Chen +1
Stimulated by the small/large Fermi surface controversy in the cuprates we consider a small number of holes injected into the bilayer antiferromagnet. The system has an O(3) quantu…
Fermi Surface Reconstruction by Dynamic Magnetic Fluctuations
Michael Holt, Jaan Oitmaa, Wei Chen +1
We demonstrate that nearly critical quantum magnetic fluctuations in strongly correlated electron systems can change the Fermi surface topology and also lead to spin charge separat…
Three dimensional generalization of the - Heisenberg model on a square lattice and role of the interlayer coupling
Michael Holt, Oleg P. Sushkov, Daniel Stanek +1
A possibility to describe magnetism in the iron pnictide parent compounds in terms of the two-dimensional frustrated Heisenberg - model has been actively discussed recent…
Pnictides as frustrated quantum antiferromagnet close to a quantum phase transition
Goetz S. Uhrig, Michael Holt, Jaan Oitmaa +2
We present a detailed description of the dynamics of the magnetic modes in the recently discovered superconducting pnictides using reliable self-consistent spin-wave theory and ser…
