Europhys. and Rev. We find that the observations in [Mizukami etal., 2011] are consistent with BKT transition.

Y.Yanase, WebThe behaviour of this system is similar to that of the antiferromagnetic XY model on the same lattice, showing the signature of a Berezinskii-Kosterlitz-Thouless transition, associated to vortex-antivortex unbinding, and of an Ising-like one due to the chirality, the latter occurring at a slightly higher temperature. . The Kosterlitz-Thouless transition shows up as an abrupt resistance shift at a critical temperature. After pointing out the relevance of this nontrivial problem, we discuss the phase diagram, which is far richer than the corresponding short-range one. >> S.Komiyama, A direct consequence of the reduced proximity effect is an enhanced c axis resistivity, which can be measured directly in experiment. At low temperatures and large This enables us to measure the phase correlation function, which changes from an algebraic to an exponential decay when the system crosses the Berezinskii-Kosterlitz-Thouless (BKT) transition. ( WebWith several measures borrowed from quantum information theory, three different types of singularities are found for the first-order, second-order, and Kosterlitz-Thouless phase transitions, respectively, and the values of transition points and critical exponents are accurately determined. Assume a field (x) defined in the plane which takes on values in = E Here, we try to understand where such a large renormalization may come from. 0000002396 00000 n WebThe system of superconducting layers with Josephson coupling J is studied.

The combination of f-electron physics, low dimensionality and interface effects provides a rare opportunity to study new states in strongly correlated electron systems, e.g. This has enabled the exploration of novel aspects of emergent phenomena in low dimensional systems with unprecedented control. . . Conclusions: In conclusion, we have proposed that superconducting transition in the heavy fermion superlattice of Mizukami et al. In the early 1970s, Vadim Berezinskii 1, Michael Kosterlitz, and David Thouless 2,3 introduced the idea of a topological phase transition in which pairs of This is a specific case of what is called the MerminWagner theorem in spin systems. 0 The following discussion uses field theoretic methods. We have also shown that magnetic fluctuations modify the conventional BKT discussion since they reduce the vortex core energy, and thus quantum criticality may strongly influence the phase diagram of the vortex system.
