Evidence for a nematic component to the hidden-order parameter in URu2Si2 from differential elastoresistance measurements.
For materials that harbour a continuous phase transition, the susceptibility of the material to various fields can be used to understand the nature of the fluctuating order and hence the nature of the ordered state. Here we use anisotropic biaxial strain to probe the nematic susceptibility of URu2Si2, a heavy fermion material for which the nature of the low temperature 'hidden order' state has ...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولHidden topological order in the heavy fermion metal URu2Si2
We present a novel order parameter for the hidden order state of URu2Si2. We show via ab-initio calculation and low-energy effective tight-binding model that an incommensurate Fermi surface nesting in the partiallyfilled f -states renders a spin-orbit coupling density wave in the hidden-order state. An observable quantity for this order parameter is the polarized total angular momentum ∆mJ=±2, ...
متن کاملComplex Landau-Ginzburg theory of the hidden order in URu2Si2
We develop a Landau-Ginzburg theory of the hidden-order phase and the local moment antiferromagnetic phase of URu2Si2. We unify the two broken symmetries in a common complex-order parameter and derive many experimentally relevant consequences such as the topology of the phase diagram in magnetic field and pressure. The theory accounts for the appearance of a moment under application of stress a...
متن کاملField-induced spin-density wave beyond hidden order in URu2Si2
URu2Si2 is one of the most enigmatic strongly correlated electron systems and offers a fertile testing ground for new concepts in condensed matter science. In spite of >30 years of intense research, no consensus on the order parameter of its low-temperature hidden-order phase exists. A strong magnetic field transforms the hidden order into magnetically ordered phases, whose order parameter has ...
