un 1 99 9 Quantum Grammars
We consider quantum (unitary) continuous time evolution of spins on a lattice together with quantum evolution of the lattice itself. In physics such evolution was discussed in connection with quantum gravity. It is also related to what is called quantum circuits, one of the incarnations of a quantum computer. We consider simpler models for which one can obtain exact mathematical results. We pro...
متن کاملEnvelope frequency response function calculation of un- certain structures
Requirements for the dynamic properties of a mechanical structure are commonly expressed in terms of eigenfrequencies. Therefore, during the design phase of a mechanical structure much attention is paid to natural frequencies and mode shapes. However, these modal properties tend to vary strongly if small variations are applied on the design model. Therefore, the presence of open design decision...
متن کاملUn petit cercle, un grand exemple (دایره‌ای کوچک، سرمشقی بزرگ )
نام هانری کربن با دو دایره گره خورده است: دایرة ارانوس و دایرة تهران؛ دایره‌هایی که مطابق منظر کربن، می‌توان آنها را به‌درستی رمزی و مثالی خواند. این مقاله به دایرة تهران اختصاص دارد، دایره‌ای تحقیقی که با حضور اندیشمندانی چند، و با محوریت دو شخصیت از شرق و غرب، علامه سید محمد حسین طباطبایی و هانری کربن، شکل می‌گرفت. برغم همه مشکلات فنی و فیزیکی ارتباط کلامی، این دو مرد، به خوبی با یکدیگر «مقاب...
متن کاملJ un 1 99 7 Two electron dynamics in photodetachment
We present the results of experimental studies of photon-negative ion interactions involving the dynamics of two electrons. Resonances associated with doubly excited states of Li − and He − have been observed using laser photodetachment spectroscopy. Total and partial photode-tachment cross sections have been investigated. In the former case, the residual atoms are detected irrespective of thei...
متن کاملJ un 1 99 7 Diffusion process in a flow
We establish circumstances under which the dispersion of passive contaminants in a forced, deterministic or random, flow can be consistently interpreted as a Markovian diffusion process. In case of conservative forcing the repulsive case only, F = ∇V with V (x, t) bounded from below, is unquestionably admitted by the compatibility conditions. A class of diffusion processes is exemplified, such ...
