Keldysh technique and nonlinear σ–model: basic principles and applications
The purpose of this review is to provide a comprehensive pedagogical introduction into Keldysh technique for interacting out–of–equilibrium fermionic and bosonic systems. The emphasis is put on a functional integral representation of underlying microscopic models. A large part of the review is devoted to derivation and applications of nonlinear σ–model for disordered metals and superconductors....

15 صفحه اولLinear and non-linear spectroscopy of microparticles: basic principles, new techniques and promising applications.
In the introduction a brief recollection is made of how one of us (RKC), accidentally, got into this field of linear and nonlinear spectroscopy of a dielectric micro-particle that can be treated as a micro-cavity or a micro-resonator. The basic principles of whispering gallery modes (WGMs) and their relationship with electromagnetic theory are presented. To simplify the mathematics, we only dis...
متن کاملMRI: Basic Principles and Applications
In the second chapter and throughout the book, Dr. Gustavii identifies common problems of non-native English speakers, a topic overlooked in Day's book. Even native English writers will benefit from his clarifications and suggestions, such as avoiding the use of "respectively" and "and/or." Another strength of the book is the cogent discussion of which researchers on a project deserve authorshi...
متن کاملMathematical Model of Unsteady Groundwater Flow Through Aquifers and Calibration Via a Non-Linear Optimization Technique
In this study, the general partial differential equation of unsteady groundwater flow through non-homogeneous and anisotropic aquifer was solved by the fully implicit finite difference method with control volume approach. The calibration of permeability and storage coefficients as model parameters was performed by a transformation technique and application of Powell's non-linear optimization me...
