Quantum spin model with frustration on the union jack lattice
Frustrated lattice spin models in two dimensions have attracted much discussion in recent years. They exhibit new and interesting phase structures and phase transitions; in particular, they may develop “spin-liquid” states, without longrange order.1 It is also believed that frustrating interactions may play a role in the high-temperature superconducting cuprate materials. Primary examples are t...

متن کاملAsymptotic incidence energy and Laplacian-energy-like invariant of the Union Jack lattice
The incidence energy I E (G) of a graph G, defined as the sum of the singular values of the incidence matrix of a graph G, is a much studied quantity with well known applications in chemical physics. The Laplacian-energy-like invariant of G is defined as the sum of square roots of the Laplacian eigenvalues. In this paper, we obtain the closed-form formulae expressing the incidence energy and th...
متن کاملThe Iranian Communists and The Soviet Union
Iran's relation with one of the largest countries, that is, Russia (The Soviet Union) has under gone many changes. One of the brilliant examples of the changing policies of Russia towards Iran is, no doubt, the years 1941 to 1953. In this period, most of graceful communist parties' rise and fall is making relations between Iran and Russia. Tudeh party, Ferghe Democrate Azerbaijan and Ferghe Dem...
متن کاملFrom Jack to Double Jack Polynomials via the Supersymmetric Bridge
The Calogero–Sutherland model occurs in a large number of physical contexts, either directly or via its eigenfunctions, the Jack polynomials. The supersymmetric counterpart of this model, although much less ubiquitous, has an equally rich structure. In particular, its eigenfunctions, the Jack superpolynomials, appear to share the very same remarkable combinatorial and structural properties as t...
