    Anderson localization in a correlated fermionic mixture

    Full text link
    A mixture of two fermionic species with different masses is studied in an optical lattice. The heavy fermions are subject only to thermal fluctuations, the light fermions also to quantum fluctuations. We derive the Ising-like distribution for the heavy atoms and study the localization properties of the light fermions numerically by a transfer-matrix method. In a two-dimensional system one-parameter scaling of the localization length is found with a transition from delocalized states at low temperatures to localized states at high temperature. The critical exponent of the localization length is ν0.88\nu\approx 0.88.Comment: 5 pages, 4 figure

    The Role of Source Trust in Priming

    In a classic experiment, Srull and Wyer (1979) showed that when participants were incidentally exposed to a number of words related to a trait (e.g., hostility), their subsequent judgments of a target person were influenced by these primes. Recent work in social cognition, however, has shown that the use of accessible information can often be affected by cues to validity (e.g., Loersch & Payne, 2009). In the current research, we explored whether the attributional cue of trustworthiness could affect the impact of trait primes. The design of the study was a 2 (prime: hostile vs. kind) x 2 (source: trustworthy vs. untrustworthy). To test the hypothesis, participants read a paragraph about a fictional person written by either a trustworthy or untrustworthy source. While reading this information, participants were subliminally primed with one of two trait concepts. Then, participants made judgments about the fictional person’s traits. The results showed that trait priming interacted with source trust to affect participants’ subsequent judgments.No embarg

    Scythian female warriors in the south of Eastern Europe

    The article is devoted to the funerary complexes of Scythian female warriors in the territory of the European Scythia. Types and sizes of graves, as well as the nature of the funeral rite of Amazons correspond to Scythian canons and de facto do not differ from men’s graves The analysis of the funerary inventory allows us to date them within the second half of the 7th till the 2nd centuries BC
