Transport anomalies in a simplified model for a heavy electron quantum critical point
P. Coleman, J. B. Marston, A. J. Schofield
We discuss the transport anomalies associated with the development of heavy electrons out of a neutral spin fluid using the large-N treatment of the Kondo-Heisenberg lattice model.…
Itinerancy and Hidden Order in
V. Tripathi, P. Chandra, P. Coleman
We argue that key characteristics of the enigmatic transition at in indicate that the hidden order is a density wave formed within a band of composite qua…
Schwinger Boson approach to the fully screened Kondo model
J. Rech, P. Coleman, G. Zarand +1
We apply the Schwinger boson scheme to the fully screened Kondo model and generalize the method to include antiferromagnetic interactions between ions. Our approach captures the Ko…
Quantum criticality
P. Coleman, A. J. Schofield
As we mark the centenary of Albert Einstein's seminal contribution to both quantum mechanics and special relativity, we approach another anniversary--that of Einstein's foundation…
Sum Rules and Ward Identities in the Kondo Lattice
P. Coleman, I. Paul, J. Rech
We derive a generalized Luttinger-Ward expression for the Free energy of a many body system involving a constrained Hilbert space. In the large limit, we are able to explicity…
Can Frustration Preserve a Quasi-Two-Dimensional Spin Fluid?
Marianna Maltseva, P. Coleman
Using spin-wave theory, we show that geometric frustration fails to preserve a two-dimensional spin fluid. Even though frustration can remove the interlayer coupling in the ground-…
