Determination of the superconducting energy gap of Rb3C60 by electronic Raman scattering

Electronic Raman scattering of Tl-2223 and the symmetry of the ̋superconducting gap

Single crystalline Tl2Ba2Ca2Cu3O10 was studied using electronic Raman scattering. The ̋renormalization of the scattering continuum was investigated as a function of the scattering geometry to determine the superconducting energy gap 2∆( $ ) k . The A1gand B2g-symmetry component show a linear frequency behavior of the scattering intensity with a peak related to the energy gap, while the B1g-symme...

Symmetry of the superconducting gap in HgBa2CaCu2O6+δ single crystals from electronic Raman scattering

Pure electronic Raman spectra with no phonon structures superimposed on the low energy electronic continuum, are reported for the first time, in optimally doped HgBa2CaCu2O6+δ single crystals (Tc = 126 K). Our low temperature spectra (15 K) for the A1g, B1g and B2g symmetries exhibit striking differences with previous data in Bi2Sr2CaCu2O8+δ . The shape of the spectra for the various symmetries...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
