Recursion method and one-hole spectral function of the Majumdar-Ghosh model
We consider the application of the recursion method to the calculation of one-particle Green’s functions for strongly correlated systems and propose a new way how to extract the information about the infinite system from the exact diagonalisation of small clusters. Comparing the results for several cluster sizes allows us to establish those Lanczos coefficients that are not affected by the fini...
متن کاملThe Matrix Product Formalism and the Generalization of Majumdar-Ghosh Model to Arbitrary Spins
We introduce a simple representation for irreducible spherical tensor operators of the rotation group of arbitrary integer or half integer rank and use these tensor operators to construct matrix product ground states for quantum spin chains of arbitrary spin with nearest and next-nearest neighbor interactions. The ground states of these quantum spin chains are doubly degenerate and are in the f...
متن کاملHole spectral function and two-particle-one-hole response propagator.
The fragmentation of one-nucleon knock-out strength at low energies is considered from the viewpoint of the two particle-one hole ~and two holeone particle! response propagator. The aim is to deal with particleparticle ~and hole-hole! as well as particle-hole collectivity simultaneously. This is achieved on a TammDancoff level by the so-called Faddeev approximation of the 2p1h propagator. Resul...
متن کاملLocalization of spinons in random Majumdar-Ghosh chains.
We study the effect of disorder on frustrated dimerized spin-1/2 chains at the Majumdar-Ghosh point. Using variational methods and density-matrix renormalization group approaches, we identify two localization mechanisms for spinons which are the deconfined fractional elementary excitations of these chains. The first one belongs to the Anderson localization class and dominates at the random Maju...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
