Heavy fermions and quantum phase transitions

Q Si, F Steglich - Science, 2010 - science.org
Quantum phase transitions arise in many-body systems because of competing interactions
that promote rivaling ground states. Recent years have seen the identification of continuous …

Singular or non-Fermi liquids

CM Varma, Z Nussinov, W Van Saarloos - Physics Reports, 2002 - Elsevier
An introductory survey of the theoretical ideas and calculations and the experimental results
which depart from Landau Fermi liquids is presented. The common themes and possible …

Locally critical quantum phase transitions in strongly correlated metals

Q Si, S Rabello, K Ingersent, JL Smith - Nature, 2001 - nature.com
When a metal undergoes a continuous quantum phase transition, non-Fermi-liquid
behaviour arises near the critical point. All the low-energy degrees of freedom induced by …

Non-Fermi-liquid behavior in a heavy-fermion alloy at a magnetic instability

H Löhneysen, T Pietrus, G Portisch, HG Schlager… - Physical review …, 1994 - APS
The specific heat C and electrical resistivity ρ of the heavy-fermion alloy CeCu 5.9 Au 0.1
exhibit non-Fermi-liquid behavior well below 1 K, ie, C/T∝-ln (T/T 0) and ρ= ρ 0+ A'T, over …

Antiferromagnetic spin fluctuation and superconductivity

T Moriya, K Ueda - Reports on Progress in Physics, 2003 - iopscience.iop.org
In this review, we summarize the present status of theories of the spin fluctuation (SF)
mechanism in explaining anomalous or non-Fermi liquid behaviours and unconventional …

[BOEK][B] Quantum scaling in many-body systems

M Continentino - 2017 - books.google.com
Quantum phase transitions are strongly relevant in a number of fields, ranging from
condensed matter to cold atom physics and quantum field theory. This book, now in its …

The electrodynamic response of heavy-electron compounds

L Degiorgi - Reviews of Modern Physics, 1999 - APS
This review discusses the heavy-electron compounds and related materials from the
perspective of their electrodynamic response. The investigation of the electrodynamic …

Disorder-driven non-Fermi-liquid behavior in Kondo alloys

E Miranda, V Dobrosavljević, G Kotliar - Physical review letters, 1997 - APS
We show how a model of disordered Anderson lattices can account for many non-Fermi-
liquid features observed in some Kondo alloys. Because of the exponential nature of the …

Kondo disorder: a possible route towards non-Fermi-liquid behaviour

E Miranda, V Dobrosavljevic… - Journal of Physics …, 1996 - iopscience.iop.org
We present a general model of disorder in Kondo alloys that, under certain conditions, leads
to non-Fermi-liquid behaviour. The central underlying idea is the presence of a distribution …

The two-channel Kondo route to non-Fermi-liquid metals

DL Cox, M Jarrell - Journal of Physics: Condensed Matter, 1996 - iopscience.iop.org
We present a pedagogical and critical overview of the two-channel Kondo model and its
possible relevance to a number of non-Fermi-liquid alloys and compounds. We survey the …
