شهرستان دزفول در بخش شمالغربی خوزستان با مساحت 4700 کیلومتر مربع و جمعیت 380416 (1375 ) واقع شده است . دزفولیها به گویش دزفولی تکلم می کنند ، گویشی که جز دسته جنوبی زبانهای ایرانی است . در این پایان نامه نویسنده قصد دارد گروه فعلی گویش دزفولی را توصیف کند. همچنین به بحث در باره ریشه فعلی و ستاک های مختلف ، ساخت سببی ، فعل های منظم و نامنظم ، ویژگیهای فعل مانند زمان ، وجه و نمود می پردازد در فصل...
Spin chain description of rotating bosons at ν = 1
We consider bosons at Landau level filling ν = 1 on a thin torus. In analogy with previous work on fermions at filling ν = 1/2, we map the low-energy sector onto a spin-1/2 chain. While the fermionic system may realize the gapless XYphase, we show that typically this does not happen for the bosonic system. Instead, both delta function and Coulomb interaction lead to gapped phases in the bosonic...
متن کاملAn extended massless phase and the Haldane phase in a spin - 1 isotropic antiferromagnetic chain
We study the phase diagram of isotropic spin-1 models in the vicinity of the Uimin-Lai-Sutherland (ULS) model. This is done with the help of a level-one SU (3) Wess-Zumino-Witten model with certain marginal perturbations. We find that the renormalization group flow has infrared stable and unstable trajectories divided by a critical line on which the ULS model is located. The infrared unstable t...
متن کاملQuasilocal Conserved Operators in the Isotropic Heisenberg Spin-1/2 Chain.
Composing higher auxiliary-spin transfer matrices and their derivatives, we construct a family of quasilocal conserved operators of isotropic Heisenberg spin-1/2 chain and rigorously establish their linear independence from the well-known set of local conserved charges.
