متن کاملEffective model of the electronic Griffiths phase
The recent discovery of a number of heavy fermion materials with non-Fermi liquid (NFL) thermodynamic and transport properties has been followed by a significant theoretical effort to understand the origin of the NFL behavior.1 In the cleaner systems, the proximity to a quantum critical point appears to dominate many of the observed properties.2–10 In other heavy fermion systems disorder seems ...
متن کاملSpin-liquid behavior in electronic griffiths phases.
We examine the interplay of the Kondo effect and the RKKY interactions in electronic Griffiths phases using extended dynamical mean-field theory methods. We find that sub-Ohmic dissipation is generated for sufficiently strong disorder, leading to the suppression of Kondo screening on a finite fraction of spins, and giving rise to universal spin-liquid behavior.
متن کاملIsotropic-nematic transition of surface embedded polymers and the associated tubulization transition of the embedding surface.
A self-interacting polymer can undergo an orientational ordering transition, depending on the magnitude of the nematic interaction. The effect of embedding such a polymer into a flexible surface on this transition is studied on the mean-field level. Renormalized values of the elastic constants of the ‘‘dressed’’ surface are derived as functions of the orientational order parameter of the polyme...
متن کاملNematic Order near a Tricritical Nematic - Smectic a Phase Transition
The nematic to smectic A (NA) phase transition in liquid crystals has been a subject of extensive study in recent years. The original theories due to McMillan [ I] and de Gennes [ 21 suggested that this transition could be first or second order. De Gennes, using a Landau expansion of the smectic free energy, emphasized the coupling between the smectic or density order parameter, v and the nemat...
