We show that four-dimensional systems may exhibit a topological phase transition analogous to the well-known Berezinskii-Kosterlitz-Thouless vortex unbinding in two-dimensional systems. The realisation of an engineered quantum system, where predicted shall occur, is also presented. study suitable generalization sine-Gordon model four dimensions and renormalization group flow equation its coupli...

Quantum vortices in superfluids have been an important research area for many decades. Naturally, on this topic has focused two and three-dimensional superfluids, which vortex cores form points lines, respectively. Very recently, however, there growing interest the quantum simulation of systems with four spatial dimensions; raises question how would behave a higher-dimensional superfluid. In pa...

The aim of this study is to investigate a behavioral approach by anchoring bias as a criterion to explain 52-week-high strategy and trough this we can find an explain for momentum strategy at uncertainty situation, to the companies listed on the Tehran Stock Exchange. The information uncertainty criteria include the book value to market value (BV / MV), company age (Age), the size of the entity...

establishing order, integrity, consistency, and accuracy in thesauri as information storage and retrieval systems plays an important role in the organization of information. the deployment of universally accepted standards, therefore, facilitates the accomplishment of this goal. to achieve this goal, the ansi /niso z 39.19 -2005 standard offers certain rules and principles for constructing cont...
