High resolution pressure measurements in the zero-temperature limit provide a unique opportunity to study the behavior of strongly interacting, itinerant electrons with coupled spin and charge degrees of freedom. Approaching the precision that has become the hallmark of experiments on classical critical phenomena, we characterize the quantum critical behavior of the model, elemental antiferromagnet chromium, lightly doped with vanadium. We resolve the sharp doubling of the Hall coefficient at…

Signatures of quantum criticality in pure Cr at high pressure
The elemental antiferromagnet Cr at high pressure presents a new type of naked quantum critical point that is free of disorder and symmetry-breaking fields and the role of quantum critical fluctuations at the phase transition is revealed.
Chromium at high pressures : weak coupling and strong fluctuations in an itinerant antiferromagnet.
The spin- and charge-density-wave order parameters of the itinerant antiferromagnet chromium are directly measured with nonresonant x-ray diffraction as the system is driven toward its quantum
Discontinuous Hall coefficient at the quantum critical point in YbRh₂Si₂.
A high-resolution study of the Hall effect and magnetoresistivity on samples of different quality finds a robust crossover on top of a sample dependent linear background contribution, which solidify the conclusion of a collapsing Fermi surface.
Hall-effect evolution across a heavy-fermion quantum critical point
Measurements of the low-temperature Hall coefficient (RH)—a measure of the Fermi surface volume—in the heavy-fermion metal YbRh2Si2 upon field-tuning it from an antiferromagnetic to a paramagnetic state are reported.
Quantum critical behavior of the (Cr86Ru14)1−xVx alloy system
Electrical resistivity, Hall effect, specific heat, and neutron diffraction measurements are used to investigate magnetic and quantum critical behavior in a commensurate spin-density-wave (CSDW)
Neutron diffraction in a model itinerant metal near a quantum critical point
Neutron diffraction measurements on single crystals of Cr1-xVx (x=0, 0.02, 0.037) show that the ordering moment and the Neel temperature are continuously suppressed as x approaches 0.037, a proposed
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
Kohn anomalies in momentum dependence of magnetic susceptibility of some three-dimensional systems
We study a question of the presence of Kohn points, yielding at low temperatures nonanalytic momentum dependence of magnetic susceptibility near its maximum, in electronic spectra of some
Heavy-fermion quantum criticality and destruction of the Kondo effect in a nickel oxypnictide.
It is shown that a nickel oxypnictide, CeNiAsO, exhibits a heavy-fermion antiferromagnetic quantum critical point as a function of either pressure or P/As substitution, suggesting a sudden jump of the Fermi surface and a destruction of the Kondo effect.


Strongly enhanced magnetic excitations near the quantum critical point of Cr1-xVx and why strong exchange enhancement need not imply heavy fermion behavior.
A large exchange enhancement is deduced, more than an order of magnitude larger than the corresponding enhancement of the low-temperature electronic heat capacity gammaT, of the wave vector-averaged spin relaxation rate gammaave for magnetically correlated metals.
Hall effect in nested antiferromagnets near the quantum critical point.
It is found that the Hall coefficient should abruptly increase with the onset of magnetism, as recently observed in vanadium doped chromium, which is consistent with available data.
Magnetic Field-Tuned Quantum Criticality in the Metallic Ruthenate Sr3Ru2O7
It is argued that observations on the itinerant metamagnet Sr3Ru2O7 represent good evidence for a new class of quantum critical point, arising when the critical end point terminating a line of first-order transitions is depressed toward zero temperature.
Quantum Critical Behavior for a Model Magnet.
The phase diagram in the H_t−T plane is determined via magnetic susceptibility measurements and a solution of the full mean-field Hamiltonian using the known LiHoF_4 crystal-field wave functions, including nuclear hyperfine terms, accurately matches experiment.
New phase boundary in highly correlated, barely metallic V2O3.
Analysis of the T→0 diffusive metallic conductivity at the approach to the insulator-metal transition indicates a different role for correlations depending upon the means employed to effect the transition.
Sharp signature of a dx2-y2 quantum critical point in the Hall coefficient of cuprate superconductors.
There is a kink in n(Hall) at the critical value of the carrier concentration, x(c); as the critical point is approached from the ordered side, the slope of n( Hall) diverges, and Hall transport experiments in the cuprates should reveal this effect.
Onset of antiferromagnetism in heavy-fermion metals
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.

Quantum Phase Transitions
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
Non-Fermi-liquid behavior in d - and f -electron metals
A relatively new class of materials has been found in which the basic assumption of Landau Fermi-liquid theory—that at low energies the electrons in a metal should behave essentially as a collection
