Partition identities are often statements asserting that the set \(\mathcal P_X\) of partitions n subject to condition X is equinumerous P_Y\) Y. A Beck-type identity a companion \(|\mathcal P_X|=|\mathcal P_Y|\) difference b(n) between number parts in all and equals \(c|\mathcal P_{X'}|\) also P_{Y'}|\), where c some constant related original identity, \(X'\), respectively \(Y'\), on very slig...

The unusual electronic and optical properties of armchair zigzag graphene nanoribbons (GNRs) subject to in-plane transverse electric perpendicular magnetic fields have been systematically investigated. Our calculations were carried out within the generalized multi-orbital tight-binding model based on a Hamiltonian which takes into account hopping integrals among (s, $p_x$, $p_y$, $p_z$) atomic ...

The interaction of spin-polarized one-dimensional (1D) topological edge modes localized along single-atomic steps the crystalline insulator $Pb_{0.7}Sn_{0.3}Se(001)$ has been studied systematically by scanning tunneling spectroscopy. Our results reveal that coupling adjacent sets in at a step{to{step distance $d_{ss} < 25$ nm, resulting characteristic splitting single peak Dirac point spectra. ...

رابطه‌­ی شدت ترمولومینسانس براساس مدل سینتیک مرتبه‌­ی اول بدون در نظرگرفتن اثر فروکشی دمایی مورد استفاده قرار می‌­گیرد. این حالی است که به عنوان یک واقعیت فیزیکی باید روابط بیان‌­کننده‌­ی توجه گیرد. کار با نظر گرفتن برای اول، تابع جداسازی منحنی تابش جدیدی برحسب و دمای قله دست آمد. نحوی جدید حذف مشخصه‌­های دمایی، همان قبلی خود تبدیل می‌­شود. دزیمتر (400TLD-) :Mn2CaF بررسی گرفت. این‌­که ­شدت طبق ...

It is known that a two-dimensional spin system can acquire topological Hopf term by coupling to massless Dirac fermions whose energy spectrum has single cone. But it challenging realize the in condensed matter physics due fermion-doubling low-energy spectrum. In this work we propose scenario lattice models. The central aim tuning between spins and such terms contributed two cones do not cancel ...

وراثت مقاومت سفیدبالک گلخانه، Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae)، به دو ترکیب ایمیداکلوپرید و کلرپایریفوس مورد مطالعه قرار گرفت. در این پژوهش، از جمعیت فیلستان ورامین (FL) عنوان والد مقاوم فردیس کرج (FR) حساس استفاده شد. مقدار ترتیب حدودا 62/13 91/14 برابر بود. عدم وجود اختلاف معنی‌دار LC50 روی تلاقی‌های F1 (R♂×S♀) Fʹ1 (R♀×S♂) نشان داد که T. نوع اتوزومی (غیرجنسی) است. ه...

The search for large gap quantum spin Hall (QSH) and anomalous (QAH) insulators is important both fundamental practical interests. degenerate multi-orbitals $p_x,p_y$ in honeycomb lattice provides a paradigm QSH state with boosted topological of the first order atomic spin-orbit coupling. By using elementary band representation, we explore feasibility this mechanism general two-dimensional latt...

We investigate the interplay of electronic correlations and spin-orbit coupling (SOC) for a one-band two-band honeycomb lattice model. The main difference between two models concerning SOC is that in case purely non-local term basis $p_z$ orbitals, whereas with $p_x$ $p_y$ as functions it local. In order to grasp correlation effects on coupling, we apply TRILEX approach allows calculate contrib...
