Phase diagram of a frustrated Heisenberg model: From disorder to order and back again

Ground-state phase diagram of geometrically frustrated Ising-Heisenberg model on doubly decorated planar lattices

Frustrated quantum models have attracted a great research interest during the last three decades especially due to their extraordinary diverse ground-state behaviour, which often arises as a result of mutual interplay between the geometric frustration and quantum fluctuations [1]. Despite a considerable effort, the geometric frustration and its effect on magnetic properties of frustrated spin s...

From relativistic quantum fields to condensed matter and back again: Updating the Gross-Neveu phase diagram

Global phase diagram of a doped Kitaev-Heisenberg model

The global phase diagram of a doped Kitaev-Heisenberg model is studied using an SU (2) slave-boson mean-field method. Near the Kitaev limit,p-wave superconducting states which break the time-reversal symmetry are stabilized as reported by You et al. [Phys. Rev. B 86, 085145 (2012)] irrespective of the sign of the Kitaev interaction. By further doping, a d-wave superconducting state appears when...

From nominal to higher-order rewriting and back again

We present a translation function from nominal rewriting systems (NRSs) to combinatory reduction systems (CRSs), transforming closed nominal rules and ground nominal terms to CRSs rules and terms, respectively, while preserving the rewriting relation. We also provide a reduction-preserving translation in the other direction, from CRSs to NRSs, improving over a previously defined translation. Th...

the innovation of a statistical model to estimate dependable rainfall (dr) and develop it for determination and classification of drought and wet years of iran

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 ...
