Finite-temperature transition into a power-law spin phase with an extensive zero-point entropy.

چکیده
We introduce an xy generalization of the frustrated Ising model on a triangular lattice. The presence of continuous degrees of freedom stabilizes a finite-temperature spin state with power-law discrete spin correlations and an extensive zero-point entropy. In this phase, the unquenched degrees of freedom can be described by a fluctuating surface with logarithmic height correlations. Finite-size Monte Carlo simulations have been used to characterize the exponents of the transition and the dynamics of the low-temperature phase. Typeset using REVTEX 1

Pseudogap Effects in Heavy Fermions Close to a Quantum Phase Transition
Neutron-scattering experiments on heavy fermions close to a magnetic quantum critical point are suggestive of an anomalous local dynamical spin susceptibility. The possibility that this anomaly arises due to a single-particle pseudogap is explored through a study of the Kondo model with a power-law density of states, a problem which exhibits a zero-temperature phase transition at a finite Kondo...
متن کاملSpin glasses in the limit of an infinite number of spin components.
We consider spin glass models in which the number of spin components m is infinite. In the formulation of the problem appropriate for numerical calculations proposed by several authors, we show that the order parameter defined by the long-distance limit of the correlation functions is actually zero and there is only "quasi-long-range order" below the transition temperature. Nonetheless, there c...
متن کاملPROPERTIES OF ISING MAGNETIC SYSTEM FexTiS2
Analysis of frequency dependence of spin glass transition temperatures of an Ising spin glass Feo.lTiS2 shows that power law with a finite transition temperature is the most probable formula describing the experimental data. Magnetization measurement on FellaTiS2 suggests that atomically ordered FellsTiSz is an antiferrornagnet with TN = 33 K . Various transition metals are intercalated in the ...
متن کاملWilson loops, confinement, and phase transitions in large N gauge theories from supergravity
We use the recently proposed supergravity approach to large N gauge theories to calculate ordinary and spatial Wilson loops of gauge theories in various dimensions. In this framework we observe an area law for spatial Wilson loops in four and five dimensional supersymmetric Yang-Mills at finite temperature. This can be interpreted as the area law of ordinary Wilson loops in three and four dimen...
متن کاملMagnetocaloric effect in one-dimensional antiferromagnets
An external magnetic field induces large relative changes in the entropy of one-dimensional quantum spin systems at finite temperatures. This leads to a magnetocaloric effect, i.e. a change in temperature during an adiabatic (de)magnetization process. Several examples of one-dimensional spin-1/2 models are studied by employing the Jordan-Wigner transformation and exact diagonalization. During a...
