Field-induced quantum critical point in CeCoIn5.

The resistivity of the heavy-fermion superconductor CeCoIn5 was measured as a function of temperature, down to 25 mK and in magnetic fields of up to 16 T applied perpendicular to the basal plane. With increasing field, we observe a suppression of the non-Fermi liquid behavior, rho approximately T, and the development of a Fermi liquid state, with its characteristic rho=rho(0)+AT2 dependence. Th...

Existence of the Critical Point in φ Field Theory*

We consider the φ quantum field theory in two and three spacetime dimensions. In the single phase region the physical mass (inverse correlation length) m(σ) decreases continuously to zero as the bare mass parameter σ approaches a critical value σc from above. In three dimensions the critical point σc is in the single phase region and the physical mass vanishes there, m(σc) = 0. A consequence of...

Bulk singularities at critical end points: a field-theory analysis

A class of continuum models with a critical end point is considered whose Hamiltonian H[φ, ψ] involves two densities: a primary order-parameter field, φ, and a secondary (noncritical) one, ψ. Fieldtheoretic methods (renormalization group results in conjunction with functional methods) are used to give a systematic derivation of singularities occurring at critical end points. Specifically, the t...

Magnetic-field induced quantum critical point in YbRh(2)Si(2).

We report low-temperature calorimetric, magnetic, and resistivity measurements on the antiferromagnetic (AF) heavy-fermion metal YbRh(2)Si(2) ( T(N)=70 mK) as a function of magnetic field B. While for fields exceeding the critical value B(c0) at which T(N)-->0 the low-temperature resistivity shows an AT2 dependence, a 1/(B-B(c0)) divergence of A(B) upon reducing B to B(c0) suggests singular sca...

Inequalities of Critical Point Theory

A purpose of critical point theory is the counting of critical points of functions. Principal theorems in the subject state in precise terms that topological complexity of the underlying space is reflected in the existence and nature of critical points of any smooth real-valued function defined on the space. The initial development of critical point theory is peculiarly the work of one man, Mar...
