Quantum Critical Behavior for a Model Magnet.
The classical, thermally driven transition in the dipolar-coupled Ising ferromagnet LiHoF 4 sTc 1.53 Kd can be converted into a quantum transition driven by a transverse magnetic field Ht at T 0. The transverse field, applied perpendicular to the Ising axis, introduces channels for quantum relaxation, thereby depressing Tc . We have determined the phase diagram in the Ht-T plane via magneti...
متن کاملQuantum Critical Behavior of the Anisotropic Kondo Necklace Model
We have studied the effect of anisotropies on the quantum phase transition of the Kondo necklace model in dimensions D=1, 2 and 3. Both the anisotropy δ of the inter-site interaction term and anisotropy ∆ of the on-site Kondo interaction have been included. We use a bond operator method with constraints implemented in mean field approximation. Starting from the paramagnetic phase we determine t...

15 صفحه اولinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Quantum critical behavior in heavy electron materials.
Quantum critical behavior in heavy electron materials is typically brought about by changes in pressure or magnetic field. In this paper, we develop a simple unified model for the combined influence of pressure and magnetic field on the effectiveness of the hybridization that plays a central role in the two-fluid description of heavy electron emergence. We show that it leads to quantum critical...
