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 quantum criticality are usually assumed to be spatially extended, corresponding to long-wavelength fluctuations of the order parameter. But this picture has been contradicted by the results of recent experiments on a prototype system: heavy fermion metals at a zero-temperature magnetic transition. In particular, neutron… 

Quantum criticality in heavy-fermion metals

Quantum criticality describes the collective fluctuations of matter undergoing a second-order phase transition at zero temperature. Heavy-fermion metals have in recent years emerged as prototypical

Quantum criticality and global phase diagram of magnetic heavy fermions

Quantum criticality describes the collective fluctuations of matter undergoing a second‐order phase transition at zero temperature. It is being discussed in a number of strongly correlated electron

Fermi-surface collapse and dynamical scaling near a quantum-critical point

Quantum criticality arises when a macroscopic phase of matter undergoes a continuous transformation at zero temperature. While the collective fluctuations at quantum-critical points are being

Order parameter fluctuations at a buried quantum critical point

TLDR
An X-ray diffraction study of the charge density wave (CDW) in 2H-NbSe2 at high pressure and low temperature, where a broad regime of order parameter fluctuations that are controlled by proximity to a quantum critical point is observed.

Local fluctuations in quantum critical metals

We show that spatially local, yet low-energy, fluctuations can play an essential role in the physics of strongly correlated electron systems tuned to a quantum critical point. A detailed microscopic

Quantum critical fluctuations in heavy fermion compounds

The electronic properties of heavy fermion alloys are dominated by spin fluctuations which are expected to become critical when tuned by pressure to a quantum critical point (QCP), entering a

Quantum-critical phase from frustrated magnetism in a strongly correlated metal

Strange-metal phenomena often develop at the border of antiferromagnetic order in strongly correlated metals1. Previous work established that they can originate from the fluctuations anchored by the

Critical slowing down of fermions near a magnetic quantum phase transition

A universal phenomenon in phase transitions is critical slowing down (CSD) — systems, after an initial perturbation, take an exceptionally long time to return to equilibrium. It is universally

Orbital-Selective Mott Transitions: Heavy Fermions and Beyond

Quantum phase transitions in metals are often accompanied by violations of Fermi liquid behavior in the quantum critical regime. Particularly fascinating are transitions beyond the

Abstract We give a general introduction to quantum phase transitions in strongly correlated electron systems. These transitions, which occur at zero temperature when a non-thermal parameter g such as

QUANTUM CRITICAL BEHAVIOR IN KONDO SYSTEMS

This article briefly reviews three topics related to the quantum critical behavior of certain heavy-fermion systems. First, we summarize an extended dynamical mean-field theory for the Kondo lattice,

Onset of antiferromagnetism in heavy-fermion metals

TLDR
Evidence is found for an atomically local contribution to the magnetic correlations which develops at the critical gold concentration, corresponding to a magnetic ordering temperature of zero, which implies that a Fermi-liquid-destroying spin-localizing transition, unanticipated from the spin density wave description, coincides with the antiferromagnetic quantum critical point.

TLDR
I reexamine the work of Hertz on quantum phase transitions in itinerant fermion systems and obtains different regimes of behavior of the correlation length and free energy in the disordered phase of the effective bosonic theory.

Interplay of Disorder and Spin Fluctuations in the Resistivity near a Quantum Critical Point

The resistivity in metals near an antiferromagnetic quantum critical point (QCP) is strongly affected by small amounts of disorder. In a quasi-classical treatment, we show that an interplay of

A systematic method for the computation of nite temperature (T ) crossover functions near quantum critical points close to, or above, their upper-critical dimension is devised. We describe the

Spin-fermion model near the quantum critical point: one-loop renormalization group results

TLDR
Two new effects are found: (i) Fermi surface becomes nested at hot spots, and (ii) vertex corrections give rise to anomalous spin dynamics and change the dynamical critical exponent from z = 2 to z>2.
