Relieving the fermionic and the dynamical sign problem: Multilevel Blocking Monte Carlo |
|

This article gives an introduction to the multilevel blocking (MLB) approach to both the fermion and the dynamical sign problem in path-integral Monte Carlo simulations. MLB is able to substantially relieve the sign problem in many situations. Besides an exposition of the method, its accuracy and several potential pitfalls are discussed, providing guidelines for the proper choice of certain MLB parameters. Simulation results are shown for strongly interacting electrons in a 2D parabolic quantum dot, the real-time dynamics of several simple mode . . . . |

Linear Controller Design: Limits of Performance |

|
The main topic of the book is closed-loop design and the computation
of performance limits using convexity. The book introduces a standard
framework for the control design problem and describes many practical
design specifications in this framework. It is shown that many of
these specifications are closed-loop convex; the corresponding control
design problems can therefore be cast as infinite-dimensional
nondifferentiable convex optimization problems. The book shows how
these problems can be solved using the ellipsoid and cutting-plan . . . . |

Linear Matrix Inequalities in System and Control Theory |

|
In this book the authors reduce a wide variety of problems arising in system and control theory to a handful of convex and quasiconvex optimization problems that involve linear matrix inequalities. These optimization problems can be solved using recently developed numerical algorithms that not only are polynomial-time but also work very well in practice; the reduction therefore can be considered a solution to the original problems. This book opens up an important new research area in which convex optimization is combined with system and control . . . . |

This is a self-contained set of lecture notes on instantons in (super) Yang-Mills theory in four dimensions and in quantum mechanics. First the basics are derived from scratch: the regular and singular one-instanton solutions for Yang-Mills theories with gauge groups SU(2) and SU(N), their bosonic and fermionic zero modes, the path integral instanton measure, and supersymmetric Yang-Mills theories in Euclidean space. Then we discuss applications: the \theta-angle of QCD, the solution of the U(1) problem, the way Higgs fields solve the large-ins . . . . |

Fluctuation-Dissipation: Response Theory in Statistical Physics |

General aspects of the Fluctuation-Dissipation Relation (FDR), and Response Theory are considered. After analyzing the conceptual and historical relevance of fluctuations in statistical mechanics, we illustrate the relation between the relaxation of spontaneous fluctuations, and the response to an external perturbation. These studies date back to Einstein's work on Brownian Motion, were continued by Nyquist and Onsager and culminated in Kubo's linear response theory.
The FDR has been originally developed in the framework of statistical mechani . . . . |

An Introduction to Topos Physics |

|
|
The basic notion of how topoi can be utilized in physics is presented here. Topos and category theory serve as valuable tools which extend our ordinary set-theoretical conceptions, can further the study of quantum logic and give rise to new and 'neo-realistic' descriptions of quantum physics, i.e. make possible the construction of a general scheme for quantum physics, which 'looks like' the classical one. A novel way of writing theories of physics, by representing a formal language of a physical system, into an appropriate topos, is analyzed he . . . . |

The large deviation approach to statistical mechanics |

|
The theory of large deviations is concerned with the exponential decay of probabilities of large fluctuations in random systems. These probabilities are important in many fields of study, including statistics, finance, and engineering, as they yield valuable information about the large fluctuations of a random system around its most probable state or trajectory. In the context of equilibrium statistical mechanics, the theory of large deviations provides exponential-order estimates of probabilities that refine and generalize Einstein's theory of . . . . |

The boundary element method (BEM) is an important technique in the computational solution of engineering or scientific problems. In applying the boundary element method, only a mesh of the surfaces is required, making it easier to use and often more eficient that the more common finite element method. . . . . |

In the context of the new standard LambdaCDM cosmology we resolve conflicts in the literature regarding fundamental aspects of the expansion of the universe and cosmic horizons and we link these concepts to observational tests. We derive the dynamics of a non-comoving galaxy and use this to demonstrate the counter-intuitive result that objects at constant proper distance can have a non-zero redshift. Receding galaxies can be blueshifted and approaching galaxies can be redshifted, even in an empty universe for which one might expect special rela . . . . |

Nuclear Magnetic Resonance: applications to organic chemistry |

This brief book is the outgrowth of some forty lectures in which it was attempted to explain the phenomenon of nuclear magnetic resonance absorption and the uses of high-resolution nuclear magnetic resonance spectroscopy to organic chemists whose background, like that of the author, has often been deficient in nuclear and electromagnetic theory. Quite a number of suggestions were received for presentation of the material in printed form with illustrations based on the lecture slides. This has now been done, and it is hoped that the result will . . . . |

Anyone who can find the roots of x^4 - 5x^2 4x = 0 graphically, analytically, or by successive substitutions can obtain the energy levels and calculate the [Greek pi]-electron energy of bicyclo[1.1.0]butadiene.

Green's functions for solving differential equations, in non-boundary value problems in near-field optics and in quantum transport through point contacts.
This introduction to Green's functions is based on their role as kernels of differential equations. The procedures to construct solutions to a differential equation with an external source or with an inhomogeneity term are put together to derive the Dyson equation for the Green's function of the inhomogeneous system.

THIS BOOK WAS DEVELOPED from my lectures on chemical bonding in Chemistry 10 at Columbia in in the spring of 1962, and is mainly intended for the undergraduate student in chemistry who desires an introduction to the modern theories of chemical bonding. The material is designed for a one-semester course in bonding, hut it may have greater use as a supplementary text in the undergraduate chemistry curriculum. The book starts with a discussion of atomic structure and proceeds to the principal subject of chemical bonding. . . . . |
