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...
15 صفحه اولMechanisms for Laser Control of Chemical Reactions
During the past several years our group has developed and employed a new technique for realistic simulations of the interaction of light with matter. Recent simulations of laser pulses interacting with molecules clearly demonstrate the potential for control of chemical reactions, through various mechanisms which include the following: (i) excitation of electrons to states which have different b...
متن کاملQuantum Indistinguishability in Chemical Reactions
Quantum indistinguishability plays a crucial role in many low-energy physical phenomena, from quantum fluids to molecular spectroscopy. It is, however, typically ignored in most high temperature processes, particularly for ionic coordinates, implicitly assumed to be distinguishable, incoherent and thus well-approximated classically. We explore chemical reactions involving small symmetric molecu...
متن کاملUltrafast Laser Spectroscopy of Chemical Reactions
Ultrafast laser spectroscopy has extended reaction-dynamic studies into the dcosecond and femtosecond time domain. allowing for experimintal observations of transitory fragments that occur during collision or half-collision. This ability to observe molecular reactions allows real-time viewing of energy redistributions, measurements of state-to-state rates, and tests of microscopic statistical t...
متن کامل[Analysis of enzymatic reactions by quantum chemical calculations].
Density functional theory (DFT) is now extensively used as a research tool for the investigation of structure and reactivity of biological systems; however, its high computational demands still restrict the applicability of DFT to systems of a few tens up to one hundred atoms. A combined quantum mechanical/molecular mechanical (QM/MM) approach is applicable as an important method to study whole...
