The phenomenon of superconductivity has not lost its fascination ever since its discovery in
1911. The flow of electric current without friction amounts to the realization of the old human …

Based on a block model, separating the unit cell of YBa 2 Cu 3 O 7− δ into perovskite and
rock salt blocks, the combinative energy between the two blocks in the YBa 2 Cu 3 O 7− δ …

We investigated the time and temperature dependence of photobleaching effects in R Ba 2
Cu 3 O 7− δ single crystals (R= Y, Pr) by Raman spectroscopy and Monte Carlo simulations …

We have simulated the phase diagram and structural properties of the oxygen ordering in
YBa 2 Cu 3 O 6+ x testing simple extensions of the asymmetric next-nearest-neighbor Ising …

Abstract Single crystals of NdBa 2 Cu 3 O 6+ x and LaBa 2 Cu 3 O 6+ x at oxygen
concentrations x≈ 0. 4, 0.5, and 0.76 have been investigated by hard-x-ray diffraction …

A brief overview is given of the nature and importance of proteins. Current equilibrium
theories concerning the folding process are discussed and an alternative non-equilibrium …

Kurzfassung Im Rahmen dieser Arbeit wurde die lineare thermische Ausdehnung von
entzwillingten YBa2Cu3Ox-Einkristallen mit x= 6, 3-7 in dem Temperaturbereich 150-500 K …

By means of ab initio calculations within the local density approximation to density functional
theory, we investigate the electronic structure of the 60 K superconductor YSr 2 Cu 3 O 6+ x …

We have chosen an Ising ASYNNNI (ASYmmetric Next Nearest Neighbor Interaction) model
under a grand canonical regime to investigate structural phase transition from a high …

در این مقاله انتقال ساختاری چارگوشی به راستگوشه در سیستم x+ ٦ O ٣ Cu ٢ YBa (۱≤ x≤ ۰) به
وسیله دینامیک گلوبر در شبیهسازی مونت کارلو بررسی شده است. در این شبیهسازی، فرآیند …‎
