The critical end point of quantum chromodynamics

We investigate the critical end point (CEP) of QCD with two flavours of light dynamical quarks at finite lattice cutoff a = 1/4T using a Taylor expansion of the baryon number susceptibility. We find a strong volume dependence of the position of the critical end point. In the large volume limit we obtain T /Tc ≈ 0.95 and μE B /T E ≈ 1.1, where Tc is the cross over temperature at zero chemical po...

Quantum Critical Point in Heavy Fermions

The concept that heavy fermions are close to a quantum critical point and that this proximity determines their physical behavior has opened new perspectives in the study of these systems. It has provided a new paradigm for understanding and probing the properties of these strongly correlated materials. Scaling ideas were important to establish this approach. We give below a brief and personal a...

Quantum Critical Point in Electron-Doped Cuprates

We analyze doping dependent spectral intensities and Fermi surface maps obtained recently in Nd2−xCexCuO4±δ (NCCO) via high resolution ARPES measurements, and show that the behavior of this electron-doped compound can be understood as the closing of a Mott (pseudo) gap, leading to a quantum critical point just above optimal doping. The doping dependence of the effective Hubbard U adduced by com...

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...

Fermi Liquid near a Quantum Critical Point *

We investigate the approach to the quantum critical point of a Pomeranchuk instability from the symmetric, disordered side of the phase diagram. In the low-temperature limit, a Fermi liquid description of the metal is possible and becomes exact for T → 0. We discuss in detail which features of the approach to quantum criticality can be captured within Fermi liquid theory and which are outside o...
