Quantum-critical behavior of itinerant ferromagnets
Andrey V. Chubukov, Catherine Pépin, Jerome Rech
We study the stability of the Quantum Critical Point (QCP) for itinerant ferromagnets commonly described by the Hertz-Millis-Moriya (HMM) theory. We argue that in , long-…
Pseudogaps in Nested Antiferromagnets
C. Pepin, M. R. Norman
We analyze the fluctuation corrections to magnetic ordering in the case of a 3D antiferromagnet with flat Fermi surfaces, as physically realized in the case of chromium, and find t…
The break up of heavy electrons at a quantum critical point
J. Custers, P. Gegenwart, H. Wilhelm +7
The point at absolute zero where matter becomes unstable to new forms of order is called a quantum critical point (QCP). The quantum fluctuations between order and disorder that de…
The Electronic Nature of High Temperature Cuprate Superconductors
M. R. Norman, C. Pepin
We review the field of high temperature cuprate superconductors, with an emphasis on the nature of their electronic properties. After a general overview of experiment and theory, w…
Non Fermi Liquid behavior in the under-screened Kondo model
P. Coleman, C. Pepin
Using the Schwinger boson spin representation, we reveal a new aspect to the physics of a partially screened magnetic moment in a metal, as described by the spin Kondo model. W…
