We use the recently developed critical quasiparticle theory to derive the scaling behavior associated with a quantum critical point in a correlated metal. This is applied to the magnetic-field induced quantum critical point observed in YbRh(2)Si(2), for which we also derive the critical behavior of the specific heat, resistivity, thermopower, magnetization and susceptibility, the Grüneisen coef...

Subir Sachdev† Department of Physics, Yale University P.O. Box 208120, New Haven, CT 06520-8120, USA Abstract We consider the quantum field theory of a single, immobile, spin S hole coupled to a twodimensional antiferromagnet at a bulk quantum critical point between phases with and without magnetic long-range order. We present an alternative derivation of its two-loop beta function; the results...

In this review we discuss novel phases (quantum critical points occurring only for T = 0) in (2+1)-dimensional Abelian gauge theories, which may serve as prototypes for studying the physics of nodal excitations in (underdoped) high temperature superconductors. We pay particular attention to describing the existence of novel phases related to the anomalous breaking of certain symmetries, includi...

The existence of a nontrivial critical point is proved for a functional containing an area-type term. Techniques of nonsmooth critical point theory are applied.

The electronic structure and properties of the osmaabenzenes and para substituted osmabenzenes have been explored using the hybrid density functional mpw1pw91 theory. Systematic studies on the substituent effect in para substituted osmabenzenes complexes have been studied. The following substituents were taken into consideration: H, F, CH3,OH, NH2,CN, NO<...

We show that the synchronization transition of a large number of noisy coupled oscillators is an example for a dynamic critical point far from thermodynamic equilibrium. The universal behaviors of such critical oscillators, arranged on a lattice in a d -dimensional space and coupled by nearest-neighbors interactions, can be studied using field-theoretical methods. The field theory associated wi...

after the collapse of the left extreme ideological camp (communism) in leadership with soviet :union: in 90’s; that must be consider along the collapse of the right extreme ideological camp (fascism) in the mid of twentieth century; the middle right ideological camp (liberalism) in leadership of industrial world countries, to celebrate this victory along with globalization age. in the meantime,...
