Microscopic derivation of causal diffusion equation using the projection operator method.
We derive a coarse-grained equation of motion of a number density by applying the projection operator method to a non-relativistic model. The derived equation is an integrodifferential equation and contains the memory effect. The equation is consistent with causality and the sum rule associated with the number conservation in the low momentum limit, in contrast to usual acausal diffusion equati...
متن کاملDerivation of Transport Equation in Time-Dependent Projection Operator Method
We develop a formalism to carry out coarse-grainings by using a timedependent projection operator in Heisenberg picture. A systematic perturbative expansion with respect to the interaction part of the Hamiltonian is given and the Langevin-type equation without a time-convolution integral term is obtained. This method is applied to a quantum field theoretical model and a coupled transport equati...

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
Derivation of a Master Equation for Intramolecular Relaxation Using Projection Operator Techniques in Liouville Space
A generalized master equation is derived to describe intramolecular rearrangement processes. It is an inhomogeneous equation, including m e m o r y effects. T h e derivation is based on the Liouvi l le space formalism. Because chemically relevant information is contained in the o f f -d iagonal elements o f the density matrix , a non-diagonal coarse-graining pro jec tor is used. All necessary a...
