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…
Thermodynamic singularities in the entanglement entropy at a 2D quantum critical point
Rajiv R. P. Singh, Roger G. Melko, Jaan Oitmaa
We study the bipartite entanglement entropy of the two-dimensional (2D) transverse-field Ising model in the thermodynamic limit using series expansion methods. Expansions are devel…
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…
